t ABSTRACT: By the.influence of aberration,,caused by the asymmetry of
the optical system, the chromatic aberration and other factors,
the theoretically attainable resolving power of electrostatic
electronic microscopes, which would be lituited solely by
electron diffraction and spherical aberration is not attained.
In the present paper the influence exercised by the asymmetry
of the field of electrostatic lenses and of the entire optical
system, the influence of the variation of the spherical aberration
of the lenses, and the effects of the pulsation of the accelera-
tion voltage of the instrument are investigated. Field asymmetry
depends on the geometric dimensions of the individual electrodes
of the lenses, and, first of all, the connection between the
Card 1/2 oval electrodes of the lenses and resolving power is investigated.

Microscopes
Results obtained by measurements show an incrcase in resolution
with a reduction of the oval shape of the lens electrodes. In
a similar manner the influence exercised bythe aberration from
the axial arrangement and the results obtained are shown by
four diagrams (Pigs 2,3). K is then briefly described,
stigmatizer
which is partly able to eliminate these errors. For the inves-
tigation of the spherical aberration of an electrostatic ob-
jective, in which the focal plane ofthe len3,iS outside the
range of the field,.a 6chematical drawing is Pirst given, after
which a constant of aberration is introduced. This constant
depends on the geometric dimensions of the middle electrode and
its potential. Varioas adjustments are investigated, and the
resalts obtained are shown by a table. The most satisfactory
results were obtained when the focal plane was approached as far
as possible to the lens. Finally, the influence exercised by the
pulsation of the direct current was investioated at various
amplitudes exercised by them upon resolving power. Thcre are 5
figures, 1 table, and 3 references, 1 of which is Soviet.

TITLE: simplified Electrostatic Electron Microscope (Upr-oshchenyy
elektrostaticheakiy clektrorwyly mik-roskop).
PERIODICAL: Zavodskaya Laborator-1ya, 1958, Vol. 2.1+, Nr I, pp. 92-96 (USSR)
ABSTRACT: In this paper the model of the-simplified electrostatic micro-
scope for 45 W (M3CM -45) is described. The apparatus consists
of two separate arts.- the microscope proper with feeding device
700 x5OO 3L1 400 IT and t he vacuum appa ra tus ( 700x4C0x1 150 mm) . T he
efficiency of the apparatus amounts to .50-60 R, while 1500 to .
8000-fold electron-optical enlargement is PAtained in four steps
by the potential modification of an intermediary lens. The fieid
of observation has a diameter of 62 m. The apparatus makes it pos-
sible to dea-l with 5 samples, one after the other, and to take 10
photographa (including ster--ophotographs), without hereby dis-
turbing the vacuum. By means of this microscope it is also possible
to take diffraction- and emission pictures of heated objects. In
Card 1/2 this case the cathode is replaced by the sample, and another anode

Simplified Electrostatic 3"llectron Yierascape 72-1-34/55
is fitted. In the case of the diffraction picture, a number of
lenses is taken out. In the vacuum plant the diffusion pump
"MR-40-A" and the pre-vacuum pump 7H-461" are fitted. The same
device can also be used as a vacuum atomizer, for which purpose
it is fitted out with various additional devices. The feeding de-
vice of the microscope consists of: I rectifier for .50 U, a de-.
vice for regulating cathode heatings a voltage regulator, a control
board for the microscope and the vacuum plant as well as of the
additional devices. (The following additional devices are mentioned:
a "Tesla!' transformer, a voltage stabilizer, etc.). There are
6 figures and I Slavio reference.

TITLE: A device for measuring the luminescence parameters of
fluorescent screens
PERIODICAL: Izvestiya Akademii nauk SSSR. Seriya fizicheskaya, v.:25,'
no. 4, 1961o 512-514
TEXT: This paper has been presented at the 9th Conference on Luminescence
(crystal Phosphors) which took place in Kiyev from'June 20 to 25, ig6o. it
offers a brief description of the device nF*c (PRS) developed by the authors
for theinvestiCation of the main characteristics of cathodoluminophores and
fluorescent screens.: The latest model of the PRS device is a universal
electron-optical apparatus using a system of electrostatic lenses. The
device makes it possible to investigate the resolution, the light yield,
the composition of the luminescence spectrum, and the purity of the sur-
face if exposed to an electron beam. The maximum resolution of the device
is found at 700 lines/mm) the beam voltage can be varied from 0-30 kv and
-6
the beam current from 2-10 -2-10 a. The excitation current may be in-

-5 (luminophore) is
creased up to 1-10 a. The spot diameter on the screen
constant and measures 20 mm. The operating pressure in the chamber is
(1-3)-10-4 mm Hg. 8-30 screens or 20 cuvettes with luminophore powder may
be placed into the measuring chamber. The light yield of yellow-green'or
blue screens (luminophores) is measured with selenium and antimony-cesium
photocells, respectively. The principle, design, and measuring operations
of this,device have been described earlier by the authors (Izv. AN SSSR,
Ser. fiz. 23, No. 4, 462, 466 (1959))- Here, the measurement of the spec-
tral composition of radiations is briefly described. This measurement is
very easy to do in transmitted and also reflected radiation since the
luminescence spectrum is nearly independent to obtain spectral curves, and
a sffectrograph or a monochromator is utilized. Fig. 2 shows the revolving
optical system which is used to measure luminescence spectra. The authors
thank Yu. M. Kushnir and M. A. Meyerov for advice, assistance, and interest.
There are 2 figures and 1 Soviet-bloc reference.

TEXT: Cathode polarization of Mo-cathode in molten haloids containing U
and Zr was studied. The experiments were carried out In hard glass electroly-
zers at 600 -7000C with catholyte and anolyte separated by an asbestos dia-
phragm. It was found that at an electrolysis with low Dc (0.1 a/cm2) Zr was de-
posited first. Catholyte was a molten equimolar mixture of Ila and K chlorides
or a eutectic mixture KCl-LiC1 to which a certain amount of UF4 and X2ZrF6 was
added. There are 12 references.

TECT: The nature of the interaction of BiCl with M and NaCl was
determined between 700 and 850PC- The equilibrium potentials . of metallic
bismuth were measured for this purpose in:electrolytes of different BiC13
contents in quartz test tube (Fig.). Electrolytically purified Bi was
added after complete fusion of the equimolar chloride mixture. BiC13 was
produced in the electrolyte by anodic dissolution of a part of the
Bi,contained in the crucible, A molybdenum electrode was placed in the
electrolyte contained in the quartz test tube such that the crucible served
a

diaphr
evacuated and filled -with purified helium. The Bi potentials were
measured related to the chlorine reference electrode by a highly resistant

TEXT: ~ Similar investigation had been carried out by other Soviet investigators using the same electrodes
or ones made of pressed purc uranium dioxide. The electrolytic dissolution of the above anodes in an equi-,
molar fused mixture of sodium and potassium chlorides was carr ied out at 680'C and current densiticE up
to I aMp/cM2
. The current efficiency at a current density of 0.5 aMp/CM2 is almost 100 %, but decreases with
decreasing cuff ent densities. This is apparently due to the formation of an insoluble uranium oxychlorldc
rather than of quadrivalent ions, as was believed earlier. The chief product of the anodic dissolution of
uranium in the fused salt is UC14. The amount of uranium dissolved varies from 0.025/g/arnp. hr at id
0.0015 amp/cM2 to 2.4 gla.hr at la = la/CM2. The amount of slime in the electrolyte increases with the-
carbon content of the anode and with current density. The preparation of clectiodes is discussed in delail

find the products of the anodic dissolution of carbon dioxide uranium anodes at higher current densities
The polarization of these and&s in an equiniolar mixture of fused sodium and potassium chlorides at current
densities from 10+4 to 10 alcM2 was investigated at 700 and 800'C. The electrolytic processes change with
increasing current density in the following order, 1) formation of U00,; 2) dissolution of uranium
oxychloride and uranium dioxide or their chlorination, resulting in the passage of U'+ ions into the solution'.
3) dissolution of uranium dioxide and the passage of U022' ions into the solution without the participation of
carbon, and finally, 4) the evolution of gaseous chlorine. There is I figure.

vestigations~on the anodic polarization of bismuth, lead and bismuth, alloyed with
thorium and lead. "Llhe electrolyte was prepared,using pure LIC!, NaCl, KC1. The
equimolar NaCl_KCl mixture and the eutectio KC1_LiCl Tixture were blast cleaned

jected to anodic dissolving for 3 hours at a current density of 0.05 amp/cm2. To
obtain bismuth alloy with :thorium the grit of these metals was pressed Into small
bars which were alloyed in an alundum =aolble in pure argon atmosphere at 1,3000C.
'rhis method was used to obtain bismuth alloys with 2.5 weight % thorium and ter-
nary alloys on bismuth base containing 2.5% Th + 1.0% Pb and 2.5 % Th + 5.0% Pb.
Polarization of anodes was measured in a closed refractory glass cell (Fig. 1)j
The cell was placed In a protective container In a furnace with an automatic thermo-
regulator maintaining a constant temperature of 700 � 50C. The alloy Investigated
was placed in one of the branches of the cell after melting of the electrolyte. A
molybdenum wire protected by a porcelain tube was employed as power connection. A
bismuth cathode was placed In another branch of the call. The anode potential was
measured in relation to the comparison lead electrode at the moment of polarization
current breaki with the aid of a loop oscillograph. The v1brator indices were re-
corded on a photographic film. The readings were taken with a MI P -12 (MIR-12)
microscope. The results of measurement given In a series of graphs, show that a
considerable difference exists between the anode potentials when dissolving bis-
muth and lead, and also thorium contained in the alloy, The different electro-

pressed from metal oxides and enrbon are revoruiblo with ro-
spect to the corresponding cation in chloride melts. This
allows their utilization for investirratin- the thermodynamic
processes and some reactions by measuring the omf. The author's
had found in reference 1 that ThOC12 in aelts of chlorides or

the effect of moisture and oxygen. A sharp decrease of the uranium concentra-
tion to a certain very low level was observed in the melt in all cases. The
difference of experiments conducted with theair and the argon atmsphere was
not considerable. The final concentration did not depend on the initial con-
centration. The interaction of bis.-:u--,i with uraniun-containing binary systems
was studied on 2-g batches of a mixture containing 25 weigh'. % of urani= tetra-,

salt upon bismuth behavior in alkali metal chloride melts, equilibrium potentials
of bismuth were measured in such melts, containing thorium and bismuth, at various
temperatures (950 - 1 100 K). An equimolar mixture of potassliyn and sodium
chlorides with 3.1 weight percent ThC14 and 1.7 weight percent-BiCl was used as
an electrolyte. After melting the mixture wasTefined by electrolys?s. The emf
of the cell were measured every 25 - 30 minutes,for 6 - 8.5 hours. The electro-
lyte temperature was maintained within 700 - 850*50C. After the experiment the
thorium and bismuth content of the electrolyte were analyzed. For compartson,

Mr.: To replace methods of mechanically removing tantalum coatings by the
el ectrolytical method, anodic dissolving of tantalum In KC1-LiCl melts was Inve-s-;
tigated at 1 1100 - 700'C (Fig. O-Corrosion,of tantalum metal was determined In
the melts,.to analyze the results of anodic dissolving. Anodic polarization of,
'.tantalum metal was experimentally investigated, to evaluate the sequence of anodid
:~,dissolving processes. Results: Tantalum corrosion in the melts investigated Is low
xnd increases with elevated temperatures. It changes slightly.when fluorides are
added to the melt. Highest current efficiency is obtained in a chloride bath with
a current.density below 0.5 amp/cm,2. At an increase of anode current density from
