SOV/143-59-6-7/21 The Development of the Studies of Interaction Between Ionic Crystals in the Works of the Tomsk Scientists Fifties, such work was also started at TPI. Some cry- stal properties (heat capacity, modulus of deformation and others) do not only determine the lattice energy, but also its derivatives in various parameters. Study- ing the properties of ionic crystala of haloid compounds of metals of the first and second group of D.I. Mende- leyev's system and metal oxides of the second group resulted in some data which are presented by the au- thor in the form of a comparison of the properties of ionic crystals and the energy of the crystal lattice. The author does not presont any names of personnel involved in the research in Tomsk. There are 10 graphs.

Academician N.S. Kurnakov showed that ionic solid solutions are not stable and disintegrate after some time. For checking the influence of the disintegration of solid solutions on their physical and chemical properties, sys- tems YJ-KCI and KCI-NaCl were investigated. Measurements of the electric strengtht the microhardness and structural X-ray anal- yses were performed. Solid solutions of systems KJ-KCl and KCl- Card NaCl are characterized by a low thermodynamic stability. Th 66196 SO'V/143-59-7-6/20 The Electric Strength and Microhardness of Solid Solution Crystals of Systems 10-KC1 and KC1-NaClj Disintegrating During the Growing Process from the Melt microhardness was measured by a PMT-3 device. The dependence of the microhardness of KJ-XCl and KCI-NaCl crystals is of a com- plicated nature, as shown in fig.2. The dependence of the elec- tric strength of KJ-XCl crystals on their chemical composition is shown in fig.3. The authors established that the disintegra- tion of solid solutions leads to changes of the electric strength, the microhardness, the loss angle tg d, and their properties approach those of mechanical mixtures, as indicated by Academi- cian N.S. Kurnakov for some other properties. This paper was presented at the Kafedra tekhniki vysokikh napryazheniy (Depart- Card.2/2 ment of Ifigh Voltage Engineering).

The energy of the crystal lattice was selected as the magnitude which determines the structure and the interaction of particles in a crystal lattice, A.A* Voroblyev (Ref.1). The values of the crystal lattice energy are unknown for crystals with admixtures. P&A.

The authors compare the properties of crystals and alloys with the lattice energy and the molecule doncentration. The Tomsk scientists devoted great atten- tion to studies of the mechanical properties of ion crystals. V*D* Kuznetsov (Ref.3) analyzed methods of determining the hardness of brittle bodies and developed a number of new mathodst drilling, damped oscillations, mutual grinding. V.N. Kashcheyev (Ref.4) and L.A. Indry"tae-va (Refe.5,6) showed that the hardness in the me- thod of mutual grinding does not depend on the type of the abra- sive powder used for grindingg only when the mechanical strength of the powder is several times greater than the strength of crys- tals to be ground. In this case the hardness ratio co 'incides with Card 2/4 the ratios of surface energies calculated by Born and Shtern.

Bogorodit=siy et a state on p 2166 that "it seems more correct to relate electrical losses directly with crystallochemical properties of the lattice, especially as these properties govern the lattice energy". The present author points out that the lattice energy is itself a fundamental crystallochemical property and is not governed by other such properties. Voroblyev uses Fig 3 of Ref I to show that there is a definite relationship (denied by Bogoroditskiy et al) between the lattice energy and the dielectric losses of alkali Card 1/2 halides: the losses decrease with increasing lattice energy 69439 S/139/60/000/01/013/041 E2oi/E49i On the Problem of the Relationship of Dielectric Losses of Crystals with the Energy and the Degree of Perfection of the Lattice (cf Fig I in the present communication). Bogoroditskiy et al suggest that losses in ion-relaxation polarization are governed by the lattice defects. Voroblyev supplements this suggestion by pointing out that the number of lattice defects decreases with increase of the lattice energy. Voroblyev ends his communication with criticism of Bogoroditskiy et al's interpretation of the dielectric losses of solid solutions (especially the concentration dependence of the losses). Voroblyev advises careful analysis of composition of mixed crystals and measurement of at least two properties in studies of decomposition of solid solutions.

It is well known that there is a definite periodicity in the ionisation potentials of elements,cbpending on their position in the per7Aodic table. It is argued that intermetallic compoundallare fomed when the ionisation potentials of the two metals are considerably different. Conversely, in the case of eutectic alloys, the ionisation potentials of the components are roughly the same. Solid solutions are formed-when the difference between the ionisation potentials of the components approach a certain average value. These ideas are illustrated in Table 1, in which Cardl/2 eutectic alloys are shown on the left and solid solutions The Ionisation Potentials of Atoms and the Mutual Solubility of Metals on the right. 9 1 and. %02 are the ionisation potentials and-It-9-- is the difference between them.

Breakdown phenomena of gaseous and liquid Insulation, the breakdown and destruction of solid dielectrics'and the insula- tion systems of high-voltage power equipment will be studied in this laboratory; it will also be available for experiments by stud'ents specializing in high-voitage engineering. The laboratory has a high-voltage hall of 460 m floor space, an open testing area of 4600 M2. and auxiliary buildings. The main equipment consists ofa 5000 kV outdoor and a 3000 kV indoor surge generators and a series of test transformers rated at 50 c-P-s-, 1000 kV and 1000 kVA.

The high-~voltage hall is 21 x 22 m with a height of 16 m. It has natural illumination from the southern and western sides, a ventilation system that ensures complete replacement of the air five times an hour, water-operated heating and electric lighting. For handling the equipment a 5 ton gantry crane with a span of 20 m4s available. The 3000 kV surge generator is 9 m high with cross-section dimensions of 2.5 x 4 m. The step up-rectifier system for charging the surge generators is based on a doubling circuit with a maximum voltage of 300 kV and a power consumption of 20 kVA during maximal conditions. Aphotograph is included of the 3000 kV surge generator with a sphere-sphere gap. The total weight of the generator is about 12 tons. It has equipment for automatic striking of the first discharge gap, automatic grounding on disconnecting the generator, equipment for changing the polarity of the pulse and remote control of the movement of the rod with the intermediate discharge gaps and of the bottom, 1 mm dia., metering sphere.

There is also a third surge generator, of 600 kYj made up of two stages and having an energy reserve of 17-3 W-secs when the capacitance during the surge is 96 000 pF. The screening, which in described, proved sufficient during operation of the surge generator to exclude any electromagnetic influence on the metering and radio circuits in the halls neighbouring the high-voltage hall. Test transformers are used as the high-voltage a.c. source, and are installed in two zones of the high-voltage hall. For inter- phase tests, a 250 kV, 150 kVA transformer is used. Phase insulation is tested by means of a 200 kV9 35 kVA transformer. The transformers have a stepless voltage regulation and the necessary protective equipment. For measuring the high-voltage, 50 cm dia. sphere-sphere discharge gaps and 300 kV voltmeters are provided. Liquid insulation is tested in a tank of 3 m dia. and 16 m3 volume which has a removeable lid and a bushing designed for 110 kV.

The relevant feature of the Jaboratory is its unified scientific leadership. At present, 73 scientific workers of the Institute participate in the investigations, of which three are doctors of science, 16 are candidates of science and 21 are post-graduates. The laboratory consists of three sections, each of which deals with a subject relating to the following two problems: physical and chomical properties, strength V and failure of dielectrics and semiconductors; development of radio circuits for instruments incorporating semiconductors4 In the individual sections of the laboratory, the electrical, mechanical, physical and chemical properties of single crystals of alkali- haloid salts, solid solutions, oxides of the metals of the second group of the periodic table are being studied.

In the second on the physical and :chemical properties of dielectrics, the mechanism of formation of a contact layer in dielectrics and semiconductors was studied. Extensive data on the conditions and causes of generation of cando-luminescence of industrial crystal phosphors due to the effect of flames were obtained by Docent V. A. Sokolov and formed the basis of a recent doctor dissertation. Considerable successes have been obtained In the High-voltage Division (headed by Candidate of Technical ScienceB 1. 1. Kalyatskiy) relating to the electric strength of ionic solid dielectrics; it was found that short duration impulses produce In solid dielectrics a discharge which develops in a similar manner to gas discharges. It was also found that in the case of the point electrode being of positive polarity, the average speed of the discharge increases with decreasing temperature and with increasing energy of the crystal lattice of the dielectrici the results were presented in candi'date dissertations (defended in 1958) by G.

Dmitrevs1dy and senior reader M. F~ Pisartsev, the electro- physical properties of electrically insulating concretes have been investigated. This laboratory participates in the work relating to astablishing the largest teaching and research high-voltage laboratory in Siberia. The Iligh-voltAgo Hall of this laboratory is already equipped with test transformers for 200 and 350 kV, surge generators of 3 million volt, I million volt and 600 kV. A series of transformers for 1 million volt have already been installed and -the erection has begun of a unique 5 million volt surge generator and of a 2.5 million volt electrostatic generator. This laboratory will be used for testing industrial equipment rated for voltages up to 220 kV. In the division on millimicrosecond techniques (headed by Candidate of Technical Sciences G. A. Voroblyev), the volt-second character- istics of various dielectrics are being investigated. It was found that for equal electric strength of gaps the breakdown of the dielectrics occurs 'in the following sequence: solid dielectric, gas, liquid dielectric, a conclusion of great importance from the point of view of insulation coordination. Circuits and instruments Card 4/5 S/003/60/000/008/001/002 E073/E535 The Problem Laboratory Stimulates Major Creative Work were devised which enable recordi ng on a film ultrashort (of 10- 10 see duration) voltage surges and also a fast-action arrestor for over- voltage protection of high voltage apparatus. Furthermore, 27 for single high voltage qrges with amplitudes up to 40 kV and durations up to 3.2 X 10 sec were developed, Under the leadership of Docent I~ A. Suslov, methods of calculation of video amplifiers and of designing miniature transistorized television cameras1have been developed. The theoretical and experimental work of this laboratory is reflected in 206 papers and 6 books published by the personnel; at present 12 books and 76 papers are in the process of publication. In addition, 87 papers and communications were presented at conferences. The laboratory is in contact with numerous other Soviet scientific establishments and also with the Polytechnical Institutes of "Ts-ftnkhuall (China) and Jassy (Roumania),, The studies of the Power Engineering Department have established the possibility of using concrete as a dielectric in high voltage engineering. As a result of this, the cost of building a 22 m insulated tower for the 5 million volt surge generator was reduced considerably. in eni WFDTION: Tvskky pylitelchniche k' J,M.Ktrova ar 5 oms Po ytechnical Ns'~ituttilmutenimS.M irovi 'Y1 3/181 607CV2'/04/18/034 B002YS063 AUTHORS: Yoroblyevt A# A,t Budylint B.

The 'discharge proceeds*along the (1003 plane of the crystal for a negative point electrode; it proceeds along the plane [m) and, less often, along L110] for a positive point electrode. The average value v m of the rate of propagation of the discharge was calculated (Table 2). v is consider- M ably higher for a positive than for a negative point electrodes Therefore, there is an analogy between the discharge in the crystals investigated and that in a long stretch of air.

Some of the more recent fields of application are scintillation counters, where the dielectrics with a large width of the forbidden zone of energy are used, or in exploeives (Ref.2), where the electronic and ionic processes which occasionally take Card 1/-PT S/063/60/005/005/012/021 .A051/AO29 Physico-Chemical Problems of Dielectrics place in the-dielectrics are applied. In outlining the physico-chemical properties of dielectrics, the connection between these properties are dis- cussed in reference to the energy of the lattice. It is pointed out that, since little is known of the physical processes in dielectrics when acted upon by an electrical field# chemistry and the science of electrical materi- als is mostly empirical. The physical properties of dielectrics in relation to their chemical composition and structure were studied. The dieleatrical properties of simple substances with a known chemical composition were in- vestigated (Ref.1,4-24). It was found that the main properties of the di- eleotrics (thermal resistancet binding energy of the elotron in the lattice, mechanical strength, optical properties~ etc.),were directly determined by the strength and nature of the particle bond in the lattice. Under the ef- foot of external conditions the interaction energy between these particles can be overcome and the lattice destroyed. A number of graphs are presented .indicating how the various properties are affected by the lattice energy, i. o., the energy value necessary to divide the crystal lattice, consisting of ions, to individual ions and separation of these from one another to an in- finitely large distance at a temperature of absolute zero. The case of bi- nary ionic compounds of the 'mBn type, as described by Kapustinakiy (Ref. 25), Card 2/+T~' 20623 510611601005100510121021 Physico-Chemical Problems of Dielectrics A051~AO29 is given where the calculation of the 'energy of the lattices with a coordin- ation number 6, is eatimated according to formula (I)i U - 256.1 (a + b)Wk-WB , where a is the number of cations, b the number of anions, RA + RB and WB the Valencies of the anion and tte cation, RA WA and RB the radii of the corresponding ions for. the stiucture of a lattice of the sodium chloride type. A later version of-the formula, where also the re- pulsionjas well as the attraction of the ions is considered, is given ast WA 0 W,,(a + b) 0.345 ) U W 287.2 RA + RB - (I - RA +RB (2). The ionic crystals have a high value of lattice energy and thus also a high value of thermal and mechanical strength. In the case of isodesmio ionic lattices of the same structural type, the properties of the materials are connected with the energy of the crystal lattice determined by the chemical composition. Fig-1 in a graphical representation of -the effect of the hardness according to Mooop melting point, electrical strength of the ionic crystals by the lattice energy, Fig.2 shows the same relationship for alkali earth metal oxides. From equation 1 it is seen that with a decrease in the size of the particles, which make up X Card 3M_ 2o623 S/063J60/005/005/012/021 Physico-Chemical Problems of Dielectrics A051/A029 the1att ice, tbellattice energy increases. Fig.3 represents the relationship between the change in volume of an elementary nucleus of a molecule (Rej-.3) in various compounds according to data from Y-rav analyses,.and the lattice energy for crystals of alkali-halide c3mpouncLs. Fig.4 gives the relation- ship of the number of ions n in one cm to the lattice energy for crystals of alkali-halide salts. The value of n was determined fromi N-d 23 n a 2(A1+A2) (3), where N is - 6.06,10 , d the speci Ifie gravity, A1and A 2 .atomic weights of the ions. The specific thermal capacity c , at a constant pressure, is giren in Fig. 5 in relation to the lattice cmergyp and Fig. 6 shows the relationship of the melting heat to the lattice energy. Experiments show- ed that the optical properties of ionic crystals also depend an the lattice energy. With an increase in the latter, the absorption of light changes in the infrared, visible andultraviolet regions according to certain' rules. The electronic polarizability in relation to the lattice energy for alkaline halides is shown In Fig.8 (Ref.30931). A decrease or an increase of the di- .electrical constant and of its components will be noted due to the shift in the ions corresponding to the change in the ion polarizability of the ions and their concentration with a change in the lattice energy. Fig.9 repre- Card 20623 S/063/60/005/005/0!2/021 Physico-Chemioal Problems of Dielectrics A051/AO29 sents the change in the electronic component of the dielectrical constant with a change in the lattice energy for crystal,, of the alkali-halide com- pound seriea. The relationship of the electroconductivity to the tempera- ture of ionic crystals is described by the formulas 6-=,e,le-u1 /kT + c3pe-u2/kT , where u is the activation energy of the libera- tion processes of the ions in the lattile. Experimental data showed that a significant increase of'the high-temperature range of the activation energy takes place with an increase in the lattice energy of the alkali-halide salt crystals. The Bum of the activation energies at low and high temperatures was found to depend on the lattice energy. The conclusion is drawn here that the electroconductivity of the crystals is connected with the energy of the crystal lattice in a law sequence. Other properties, such as the effect- ive mass.of the electron and the magnitude of the oscillating quantum, are also thought to depend on the lattice energy. It is pointed out here that these relationships must be accurately established. The electrical strength of the dielectric is thought to increase with an increase in the lattice energy (Pig,10). Other properties, such as the thermal resistance of the Card 5/11- 20623 s/o63/60/005/005/012/021 Physico-Chemical Problems of Dielectrics A051/ "029 icnic crystals are in a reverse relationship to the lattice energy, but this phenomenon is assumed to be illusionary, since the decomposition of these substances is also determined by the ionization potential, aswell as the lattice energy-. The reverse relationship is also observed in the case of the heterodoamic ttructures. Data obtained from Refo.9110 on a comparison of the phyaico-chemical properties of liquid and ganootto organic dielectriGa with their electrical strength in the aliphatic hydrocarbon series showed that the electrical strength changes sympatically with the change in the intermolecu- lar bond strength and does not depend on the bond strength within the mole- cule. These results were used to form a graph of the spark-over of the or- ganio dielectrlc--~ (Fig,11). Further mention is made of the connection be- tween the phy31oo-chemical properties of dielectrics and the lattice energy when the stru,.ture is destroyed. The contraversial facts noted in real crys- tale.viz., the mechanical properties of these single crystals changing ac- cording to certain rules with the change in the lattice energy, are explain- ed by the behavior of the defects, especially of dislocations, i.e., by the energy of the crystal lattice. One of the possible means for obtaining a controllAble concentration of the defects in the lattice is the formation of solid solutions. Upon investigating the electrical properties of the solid Card 6/T7- 20623 S10631601005100510121021 Physico-Chemical Problems of Dielectrics A051/AO29 solutions Cac, ZrO , a defect in their structure was noted (Ref,47). A com- plex.investiE;tioR of the physioal properties of the solid solutions KC1-RbCl, KC1-KBr, RaC!--NaBr was carried out. It was proven that the general oharac- teristio, wh:'.ch determines the physical properties of a complex dielectric, was the heat of formation. It 'is expected that a drop in the interaotion forces would involve a drop in the strength and an increase In the defeet of the solid solution. The relationship between the heat of formation of the solid aoluti3n and the average number of particles n included in the volume of the elemeatary nucleus (for an ideal single crystal n - 8) leads to the conclusion that the more heat absarbed in the formation of the solid solution, i.e., the lower the energy of interaction of the particles in the crystal lattice of the crystal,the more defective is its structure. The connection between the defectiveness of the struoture and the lattice energy leads the authore'to assume that the laws obtained for the single crystals are also ap_ plioable to the polycrystals used commercially. Finally, the authors discuss the connection between the physico-chemical properties of solid solutions of alkali-halide salts. It is said that the introduction of admixtures into the crystal can lead to a change in the interaction between the particles of the crystal lattice of the substance. Experimental data on the physico-chemical Card 7/t$- 20623 S/063/60/005/005/0'!2/021 Physico-Chemical Problems of Dielectrics A051/AO29 properties cf solid solutions of ionic compounds are compared and certain as- aumptions are therefrom derived on the interaction of ions in the investight- ed systems. The most important value characterizing solid solutions is their heat of formation and reference is made to the formula used by Grimm (Ref.61) for caluclating the energy of the crystal lattice. The heat of formation of the solid solution is estimated experimentally as the difference between the heats of dic3olution of the solid substance and the mechanical mixture of components having the same weight and composition. The connection between the heat of formation and the electrical properties of the alkali-halide polid solutions In noted. The electrical strength of NaCl-NaBr, KBr-KJ, KC1- -m3r. NaBr-Y.3r is lower than that of the components. Solid solutions formed by heat absorption have a weakened structure and are characterized by a low- ered electrical, schematic and thermal strength, high,dielectrical losses and a defective structure. The electrical characteriBtics of dielectrics are connected with other properties, e.g., in the case of ionic crystals with the lattice energy, in homeopolar crystals with the energy of atomization, in molecular.orystals with the energy of intermolecular bonds and in solid so- lutions with the amount of heat liberated in their formation.

The authors point out that in selecting new materinla for dielectrics compounds with highly-charged atoms (boron, si- licon, ete.),should be combined with non-deforming atoms creatine rigid bonds (nitrogen, fluorine, etc.). It is worthwhile to investigate the possibil- ities of uaing temperatures and pressures obtained in explosive procosses and electrical explosion3 when producing dielectrics to overcome the high activa- tion, barri~~rs of the reaction. The problem of selecting new dielectrical materials'is a matter for the chemist,as well as the physicist.

Acceleration of Electronelln a Circular Traveling-wave Iccelerator Atomnaya onergiya, 1960, Vol. 8, No. 5, pp. 459 - 461 TEXT; The suggestion to use a closed circular curved waveguide (the cross saction of which is shown on p. 459) as accelerator system was made by Voroblyev *(Ref. I); in this waveguide an electromagnetic ways with a non-vanishing y-component of the electric field propagates. The charge of tho waveguide is such that within the range of the mean ra- dius the phase velocity of the wave is v = oe The propagation of the ph waves in curved waveguides which are unlimited in the axial direction have already been investigated in an earlier paper (Ref. 2). Proceeding from the results then obtained, theauthors in the present paper in- vestigated the possibilities of a control of the particle trajectories by the wave field itself. From the results obtained in Ref. 2 the Card 113 81747 Acceleration of Electrons in a Circular B/089/60/008/o/07/008 Traveling-4ave Accelerator B006/BO56 conclusion may be drawn that 1) the curvature of the waveguide reduces the phase velocity of the cophasal waves, and 2) that the influence exerted by the curvature upon the dispersion properties of a system closed in the axial direction .is at vph --t c considerably greater than In an axially not closed system. These results are discussed. Several questions,relating to the selection of the waveguide parameters are briefly discussed. Contrary to an ordinw.-y synchrotron, the high fre- quency field in this waveguide accelerator is highly inhomogeneous in axial and radial direction (all components depend in a complex manner on r,and z). The dynamics of the particles In the cyclic waveguido accelerator is, however, similar to those in a cyclotron, and the com- :plex wave field does not disturb the norsal operation of the accelera- tor. The Puggestions for the control of particle trajectories in the curved waveguide by means of the traveling wave field, which had been made by Voroblyev already in Ref. 6, are finally discussed (stability conditions - equation (5)). These possibilities of trajectory control by the traveling wave field as well as the possibility of avoiding some technical difficulties occurring in the construction of cyclic Card 2/3 81747 Acceleration of Electrons in a.Circular 8/089/60/008/05/(Y7/008 Traveling-wave Accelerator B006/BO56 high-energy electron accelerators make the use of curved waveguides in cyclic accelerators interestinge There are I figure and 6 Soviet refe- rences* SUMIITM., March 90 1959 3/3 80028 0 SI04816010241011061009 .7 .2 B006/BO14 IUTHORSt Voroblyev, A.

In the fifties the Tomskiy politekhniehookiy institut (Tomsk Polytechnic Institute) developed a method which is used to study pulsed breakdown of solid dielectrics as well as a method employed for the production and recording of pulsed voltages with durations of down to 10-9 see. 0. 1. Voroblyev and T. D. Kuchin measured the dependence of electric strength of NaCl, M, KBr_,_&_n_d1U_single crystals upon the duration of -voltage action. It is shown that the minimum wat strongly shifted toward shorter times. This effect was explained by M. A. Mellnikov. Mellnikov also took the volt-second Card 1/4 80028 .Rules Governing Pulsed Breakdown of Solid S1048160102410110"1009 Dielectric3- B00971~14 characteristic of the same crystals with exposures from 1 10-9 see on (Fig. 2).. The corresponding results as well as those obtained from a number of.other publications are discussed in this article. K. M. Kevroleva carried out investigations of crystal hydrates, and obtained volt-second characteristics similar to those of alkali halides. Ye. A. Konorova 6 _ -8 - studied the electric strength wiWin the range I - 10- 5-10 aso without finding any change. Similar investigations carried out by MeVnikov showed that the disruptive strength increased by 15 per cent when the shortest exposure within the range 1,10-6 _ 5-10-9 see was used. Furtherv he studied the volt-a econd characteristics of pplymeral(Fig- 5), Again# he noticed that the disruptive strength inered_s_~Tt_775-20 'per cent when the shortest exposure was applied. A. V.

Next, the authors give further results concerning characteristics obtained at the Tomsk Polytechnic Institute and give a :3urvey of details reported in numerous publications on the break- down delay.

An confirmed by the data of the accompanying table, the mean velocity vm of propagation of a discharge may be satisfactorily described by the formula v M - d/tfj where d is the sample thickness.,The sentence of this equation is formulated and discussed. It. K. Sonchik determined the delay time for FaCl, KC1, KBr, and KI single crystals. Ee found that vm increases with increasing over- voltage, increasing lattice energy, and positive polarity of the peak. In the following, the authors discuss a few details concerning the depend- ence of tho breakdown voltage on the thickness of the-sample, and some rules iscovered by various authors (Sonchik, Voroblyev, Mellnikov, N.

The following rules are summarizedt 1) At high values of d a polarity effect is observable; 2) positive polarity of the peak shows a higher vm than negative polarity, vm rises with increasing overvoltagag.3) tf Increases 'With d'i 4) the second stage of discharge in alkali-halide crystals is shorter by several orders of magnitude than tf. 5) The volt-sooond charaoteristic of alkali-halide single crystal1jakes a bucket-like course. 6) In -solid dielectrics vM is of the ord er emlabc Card 3/4 WA Rules Governing Pulsed Breakdown of Solid 5/048/60/024/01/06/009 Dielectrics B006/BO14 and decreases with a rise in temperature. 7) The breakdown voltage increases in homogeneous and nonhomogeneous fields'more slowly than with the thiokne3s of the dielectric.

A suggestion is made for calculating these losses. First, only the definite results of calculations according to the methods by N. M. Blachman and E* D. Courant (Refs- 5p6), j. m. Greenberg and T. H. Berlin (Refs- 7,8) and A. N. Matveyev (Refs. 9,10) are studied and compared in a Table. This comparison shows that the various methods lead to different results. The control method and the Card 1/3 Investigation of the Losses in Electrons S/048 108)924/008/016/017 Due to Scattering in the Residual Gas in the B012~�B(067 Accelerating Chamber experimental apparatus are then described'. Fig. I shows the measuring block diagram. The results of measurements are given and compared with the results of theoretical calculations. In conclusion the following is stated: character and quantitative comparison of the curves shown in Fig. 6 indicate that the losses in electrons due to scattering in the residual gas can be calculated according to the method of Greenberg and Berlin as well as according to that of Matveyev with sufficient accuracy since the results differ only by 1.5 -* 1.7 times from one another. According to the inethod of Blachman an~ Courant the losses in protons due to scattering in the gas may be estimated, whereas for the electrons the values obtained by this method are too low. The sufficient agreement between the experimental and the theoretical results also confirm the correctness of the method of measurement chosen. V. G. Shestakov .assisted in the measurements.

Early experiments on rock malt of micron thickfiess confirm the increase in-electr-ic-strongth and delay time in thin layers and show that breakdown of solid dielectrics commences with impact ionization.

Highest breakdown voltage for negative point polarity and the polarity dependence of the direction of discharge indicate that impact ionization occurs during the formation ofthe discharge. The'faot that dis6harge propagates faster if the point is positive indicates that discharge formation in rock salt is a process similar to streamer discharge in air. Breakdown voltage and formation current are higher where the lattice energy is higher.

TITLE: Optical absor-ption in alicali-halide crystals and the lattice energy I-LRIUDICAL: Izvestiya vysshikh uchebnykh zavedeniyj Fizika, no.1, 1962, 118-124 TEXf., The author reports a review of published information on the fundamental optical absorption and additional absorption 'in ionic crystals containing colour centres. The long-wave fundamental absorption edge of ionic crystals in the ultraviolet part of the spectrum and the short-wave edge in the infrared are displaced towards longer wavelengths for lower lattice energies U. The additional absorption bands which appear in crystals of alkali-halide salts containing n- or p-type colour centres are displaced in the direction of the longer wavelengths for crystals with lower lattice energies. This displacement can be described by a formula of the form hmax,. 512.2 OL A U_Q Card 1/2 S/139/62/000/OOJL/ojLg/o32 Optical absorption in alkali-halide..

These results are said to be in agreement with the work reported by the present author in Ref.15 (AN SSSR, v.10, 1956, 47).. There are 2 figures and 7 tables.
