TITLE: Effect of -~mma irradiation upon oxide films of germanium
PERIODICAL: Akademiya nauk Uzbekskoy SSR. Izvestiya. Seriya fiz,.o-
matematicheskikh nauk, no. 1, 1962, 86-90
TEYT: The effect of gamma rays on germanium monoxide and germanium
dioxide films produced by etching was quantitatively measured with a
Geirovskiy micropolarograph. The monoxide - dioxide mixture produced by
etching germanium powder in standard etching agent did not change qnder
gamma irradiation in air, carbon dioxide, and in vacuum (jo-4 torr) with
20, 60, 100, 150, and 200 million r. In the subsequent irradiation of
the -weighed portion of germanium etched in a standard reagent with 20, 30,
50, and 100 million r, the amount of germanium dioxide increaaes at doses
Of UP to 40-50 million r, and then decreases again. The oxide film
produced in etching agent no- 5 contains monoxide and dioxide in a'A ; 1
ratio. While etching agent no- 5 gives rise to germanium monoxide,
Card 113

Effect of gamma irradiation ... B125/B104
germanium dioxide is contained in the film in an equal amount. The
anomalous current and the photocurrent are not exclusively due to the
Ogloo observed when exposlnE the
germanium monoxide. Similar phenomena are
diodes to gamma irradiation (doses above 1 r). These anomalies disappear
either entirely or partially at doses of more than 108 r. The irradiated
photodiodes yield a photocurrent at such doses if the amount of germanium
dioxide on the surface increases. The upper limit of the anomalous
photocurrent shifts toward the visible regiQn when etching agent no, 5 4.8
used. Gamma irradiation first causes the oxide film to grow more
considerably, but the secondary fast electrons then aGain partly destroy
the oxide film. As a result, the oxide film becomes eventually thinner.
If present considerations are correct, germanium diodes are made
insensitive also to intense radiations in that the oxide film is prevented
from growing all throughout the dose range. There are 1 figure, 1 table,
and 8 references: 2 Soviet and 6 non-Soviet. The four references to

ABSTRACT: The paper describes an experime ntal investigation and sets forth
theoretical relationships governing the presence of the extremely active acceptor
element B in-Si. The reaction B10(n, a W7 for neutrons with an energy of 0.03 ev
has a large. cross section (4,000 barn). This reaction yields an a particle with an
energy of 1.47 Mev, which has a short path in Si (appx. 5 micron) and a Li7 nucleus
with 0.88 Mev energy. This particle and this nucleus are distinguished by their
great total energy (Z.35 Mev) and their great ionization density which affords a
highly effective registration if the carrier medium exhibits counting properties. In
this respect Si is a very convenient material.' The block scheme of the measuring

equipment employed Is described. It comprises a Si diode a. power-supply battery,
a load resistance, and a preamplifier, all of which are placed in an aluminum shield
,and are placed at the output of the horizontal channel of the reactor. The pulses,
arising in a Si n-p junction irradiated with reactor neutrohs are rendered visible in
an oscillogram. It is shown that the irradiation of Si junctions with reactor neutrons
provides a fundamentally sound means for the determination of some impurities in
.~the material, especially H and B. It is also shown how,a junction can*be employed
;as a fast-neiltron counter, even though oiLly for assessment purpdses. The theory
.of the formation of the pulses in the ~urface-barrier n-p ju*nction is traced, using
an equivalent circuit to represent the surface-hole and -p junction. Expressions are
-developed for I(t) by the solution of the diffusion equation for various particular
cases, depending on whether the point source of the charge lies within the n region
or the region of body charge, or whether the track of the article lies entirely within
p
the n region. The formulas obtained will be employed for the calculation of the
effective volume for prescribed bounds of the changes of the amplitude of the pulses
excited by the neuirons in a diode and also for the calculation of the pulse -amplitude.

and a further reduction to 12.23 pf after 800 x 106 rep. The ca-
pacitance of a second specimen of the same type dropped from an
initial 12.80 pf to 12.50, 12.55, and 12.78 pf, respectively,'after
the same doses. A third specimen of the same type behaved similar"
ly to the first. Capacitors of the types BM and KBGM, having ini-
tial capac.itances of 0.0121 Pf and 0.0247 pf, changed their capac-
itances after an integral dose of 1100 x 106 rep to 0.0144 uf and
0.0253 pf, respectively. The PM -capacitor(4635 pf) changed its
capacitanca under the same conditions to 4622 pf, while the KSO type
(1217 pf) remained unchanged. Radiation damage was especially
apparent in paper dielectrics, evidently owing to radiolysis of the
impregnatiug oil. The BM and KBOM ca0acitors showed bulging of
the container and seepage of oil and sealing compounds. It is-con-
cluded that gamma radiation will shorten the life of capacitors,
but that even powerful doses will not lead to imn,~,diate failure.

ABSTRACT: After reviewing the merits, shortcomings and sensitivities of a number
of methods for determining B In Si, the authors point out the sensitivity of the
n-p junction of silicon to charged particles and discuss two new methods both
based on the 010(n,a)L17 reaction, in considerable detail. The first method makes
use of 479Kev X-quanta from the excited W nuclei, while the second method Is
based on the Ionization effects of cz particles in the n-p jLnCtion. From the num-
ber of registered 4791(ev V-quanta corrected for the spatial distribution of the
source, It Is estimated that one can detect a boron concentration of 1015cm-3 In
silicon. Such a concentration would be represented by 3Z-X of the I-radlatlon back-

ground whIchican be resolved. Such a background can be avoided, however, by count-
ing a-particles from the 810(n,a)L17 reaction. Methods of a-particle detection are
discussed. if one uses a phohographic plate with silicon containing 1015cm-3 of
boron in a neutron beam of 10 cm".2sec-1, one would have 5 a-particles per minute.
The other method of a-particle detection Is based on the effect of the a-particle
on the p-n junction in sillcon. The sensitivity of this method Is determined by:
a) the density of the neutron flux; b) the neutron spectrum and c) the presence
of materials,with concurrent reactions ly the sample. In the ideal case, in order
to determine a boron concentration of lo Ocm-3, one sy8uld have a junction with
an effective volume of 10-7cm in a neutron beam of 10 cm-2sec-1. However, in the
real case, one should consider the presence of fast neutrons, different nuclei,

ABSTRACT: The basic difficulty In measuring the concentration of boron Impurities
in silicon is to determine the effective volume, so that the magnitude of a pulse
can be calculated as a functlon of the position of the Ionization process relative
to the n-p junction. it Is concluded from the calculat!on of the pulse magnitude
that the effective volume Is given by the area of the n-p junction multipllcd by
the diffusion length. The roncentration of boron in silicon Is therefore given by

ABSTRACT: The author considers the use of activation analysis of germanium
samples to verify electrophysical measurements Indicating an almost compensated
acceptor concentration of 4 x 1015atoms/cc. A parallel Investigation of germanium
containing less than 1010 atoms/cc of Ga was conducted-to correct for Ga formed
by the (n,p) reaction with fast neutrons, and a combination of radlochemical and
,Y-spectral enajysis was used to Interpret e rejults. The sample was Irradiated
for 5 minutes In a reactor flux of 1.8 x IOM/cm;'-sec, etched with acid for I
min,, and the 4r-spectrum -taken with a slng'e-crystal scintl I lation spectrometer,

prepared and Irradiated along with the germanium for 8 hours In a flux of 1.8 x

the radfachemical procedures used after bmbardment to separate out each of the
impurities under study. Typical spectra are sfxNm for the reference materials
and the fractions separated fro= the ge. nium sample. the shapes of the spectra
indicating good sep3ration. This was confirmed by obtaining the decay curves of
0-activitles over 2-3 weeks. The concentration of lapuritles was calculated from
the number of counts In the phatopeaks. Formation of the Ga in the pure, control
Ge sample by (n,p) reaction was verified by calculating the reaction cross s,!ctlon,
a value of 1.3 x 102 mb being obtained. wh!ch Is close to the theoretical value
of 1.5 x 102 mb for 4 MeW neutrons, showing that there were 1017atoms/cc of Ga in
the Ge sample before Irradiation. The results of the activation analysis differeJ
substantially from those given by electrophysIcal measurements, as may occur. In

in biological research. The high sensitivity g for Mn, Cu,
As, Au, etce), small sample weight (10 mg), possLbility of simulta-
neous determination of nicroelementa, and absence of contamination
make this nethod convenient for the processing of biological materL-
als. As many as 24 aloments can be rapidly 9oparated and determined.

analysis is the separation of the activity of a given alement. This
problem can be solved by chemical separation, identification from y
spectra, 3 activity, or half life, etc., depending on the composition
Of the sample. The authors used activation analysis to study the
brains of healthy and cancerous rats, irradiating 10 ng of the tissue
for 10 min in a neutron flux (1.8 x 1013CM-2.6ec-1 and 1.2 X 1012
cm 2.0ec-1), for determination of sodium, chlorine, potassium, and
phosphorus. Activities of tpeseolements vere measured by means of a

(1 x 2 Cm), an FEU-11 photomult,iplier, and 4 PS-10000 radiometer. A de-

~ARSTRAGT: A method is described for determining gold and rhonium in ores by
:measuring the gamm-spectra of the irradiated samples. It eliminates a prolimi-
nary radiochemical separation of the isotopes. Srmples of gold ores (containing
from 0.5-40.0 g of gold per ton) and of molybdenito ores and concentrates (yith
3
a rhenium content of 0.001% and up) were exposed to irradiation of 1.8 x 10 3

-were obtained vith a mnoorystal-saintillometric s~eotrometer. It was possiblo

!provided that the aummar-I radio petivity background of Na, As, and Fo isotopes
:was not excessive. The usually high As content of the ores was reduced to 0.8%
'by heat treating the ore in a carbon are before its exposure to irradiation.
A As76
:Addi'ional reduction of the content was achieved by allowing the samples to
!stand" for 9-16 days prior to their spggtral analysis. This waitinj geriod is

,spectral line in the presence of the M699 isotope, provided that the intensity of
4the photopeak of Mo99 did not exceed that of R0186 by more than twice. Allowing
'the irradiated samples to stand for 15 hours reduced the Mo interference by doing
,away with 14o99 isotope (half life of 67 hours). Orig. art. has., 3 charts.

ABSTRACT: This paper was presented at the Inter-Collegiate
Conference on Acceleratorst held iq_Tomsk (February 1958).
It is well known that a stable equilibrium orbit will -
exist in a betatron if the magnetic field in the working
part of the gap is chosen so that H = Ho(Ro/R)n where
0 < n < 1 and H = 2HO2 where H is the mean field in
the region of the orbit of radios Rol and Ho is the
field on the orbit itself. When this condition is
satisfied, the electrons are accelerated in an orbit
having a constant radius Ro. However7 the above cond1tion
does not take into account the possible effect of the
electron current circulating in the chamber on the
Card stability conditions for the motion in other orbits having
1/4 a radius different from Ro. It is natural to suppose
that when the circulating current is sufficiently largelo/

On Certain Properties of the Capture Mechanism and the Acceleration
Process in a Betatron
there may appear another orbit of a radius greater than
Ro which will be stable during the acceleration cycle.
In that case the betatron should produce two pulses of
y radiation which are separated in time. This effect has
in fact been found in the case of the 3 MeV betatron of
the Scientific Research Institute of Nuclear Physics of
Moscow State University. This betatron has been built
specially for the purpose of studying the electron capture
mechanism. In papers concerned with the mechanism of
capture of particles in a betatron, the decrease in the
intensity of y radiation as a function of the injection
current, for currents exceeding a certain optimum value,
is explained by the defocussing effect due to surplus
electron space charge which fills the chamber during the
admission process. However, a careful analysis of the
behaviour of the electron beam circulating in the chamber
Card during the injection process shows that the defocussing
2/4 effect of the surplus electrons can only lead to a
reduction in the rate of increase of the intensity with

Process in a Betatron
increased injection current. Therefore the above effect
must be due to some other causes. It is suggested that
the decrease in the intensity for admission currents
exceeding the optimum value is due to the collective
capture mechanism whose efficiency is strongly dependent
on the injection current. In fact if the injection
currents are smaller than the optimum value and the
collective capture mechanism ensures the reduction of the
radii of instantaneous electron orbits of about 1 mm per
revolution, then for admission currents much greater than
the optimum value this orbit contraction may become very
large. As a result, the electrons will approach the
inner wall of the chamber and will be taken out of the
acceloration process. Thus for injection currents
considerably greater than the optimum value it is in
general impossible to accelerate electrons in a betatron,
because of the particle losses at the inner wall. it
Card has been found that the collective capture mechanism
3/1+ ensures maximum intensity of radiation for such injection
currents for which the efficiency of the mechanism is

still relatively low. For injection currents
considerably greater than the optimum value, the
efficiency of the collective mechanism is greater still
and the electrons leave to smaller radius orbits after
one or two revolutions, but the intensity in this case
is smaller than the limiting intensity owing to the
capture of some of the electrons by the inner walls of
Card the chamber.

TITLE- Short-Duration Pulse Gener!1_05~
PERIODICAL: Pribory i tekhnika eksperimenta, 1960, No 3, PP 73-76
ABSTRACT: At present the most suitable industrial thyratron
available for short pulse work is the TGIl-3/lAwhich
breaks down in less than 5 no with a varlation'in the
instant of breakdown of less than 1 no (see Refs 2-4).
However it will only support about I kV at the anode
and is thus suitable for low-voltage working only. The
production of high-voltage pulses requires a subsequent
amplifier. Fig I shows a suitable circuit in which the
pulse driving the thyratron is formed in valves
6P14P and 6P13s. The output stages use GI-30 valves.
The driving pulse is positive, 200 V and has a rise
time of 20 no. The pulse-forming line at the thyratron
anode is a shorted length of RK-20 coaxial cable. A
Card 1/3 capacitance of 10-20 pF is found to be necessary at the
0~

anode to improve the pulse shape. The cathode load of
the thyratron is the input impedance of the length of
terminated coaxial cable which connects the pulse to
the final amplifier. This final driving pulse is
positive, 300 V and has a rise time of 5 no. The final
amplifier offers alternative paths giving either
polarity output. Each output valve is a parallel-
connected double-tetrode. Valve L5 gives out a negative
pulse whose rise and fall times will be less than 5 ns
provided the load resistance is less than 200 ohms.
Valve L4 gives a positive output and special precautions
are necessary when driving this valve, as shown in
Fig 2. In order to transmit a flat-topped pulse of
given duration, the cable inductance must satisfy the
condition at the foot of p 75. For short pulses the
practical arrangement consists of 17 turns of RK-20
cable of adjustable pitch wound on a 40 mm diameter
Card 2/3 ceramic former containing a ferrite core. This produces

an inductance of 10 microhenries suitable for a 0.1 )isec
pulse. The interstage pulse transformer in the thyratron
drive circuit has two windings of 40 turns of TEL-0.23
wound on a toroldai ferrite core, internal diameter
2.5 cm and 0.42 em section. With 75 ohm loads the
positive output is 1 kV with a rise time of 5 ns, the
negative output is > 1 kV with a rise time < 4 na. With
a higher resistance load the positive output can be
raised to 2.5 kV in 6 na. Pulse amplitudes may be
varied smoothly by controlling the final anode supply
between 0 and 3.5 kV. At repetition frequencies up to
I kc/s the current required is only about 10 mA mean.
Fig 3 shows oscillograms of pulses with half-amplitude
durations of 8 ns and 50 ns. The marker pulses are
spaced at 8 na. The author thanks A. A. Sanin for his
assistance.

TITLE: Generator of nanosecond pulses with continuous

PERIODICAL: Pribory i tekhnika eksperimenta, 1960, No-3, PP-87-89
TEXT: The authors utilise the well known method of
generation of pulses of microsecond duration with two thyratrons,
the instants of triggering of which can be iontrolled for
generating square topped voltage pulses with a maximum amplitude
of 1.2 kV. Two thyratrons (Fig.1) feed a common load, the
resistance in the cathode of one of the thyratrons At (L4).

provided for improving the shape of the pulse and increasing the
amplitude of the triggering pulse. The stages with the tubes
41 2(L2) and J13 (L3) have the additional function of reducing
the mutual influence of the grid circuits of the thyratrons.
The surge taken from the cathode load of the thyratrons will have
a front with a rise time of 5 to 6 nanoseconds. To improve
further the steepness of the front, the formed pulse is fed to the
input of a limiter A 6 (Ld in which pulses with front rise times
below 3 nanoseconds and an amplitude of 400 V can be generated
using a relatively low anode load (50 Ohm cable). The amplitude
of this pulse can be increased to 1200 V by using one amplifier
stage, the load of which in a cable having a wave resistance of
75 Ohm. Since the tubes operate under surge conditions, only a
negative polarity pulse can be generated in the anode circuits
of the tubes under cut-off conditions. For triggering the tubes
of the output stage, the negative pulse from the previous stage
has to be inverted. This is done by means of a section of coaxial
cable which is wound onto a ferrite core. The oscillator in
triggered with pulses of 0.5 Usec and longer and with fronts of

TEXTs The experiments were carried out by means of a betatron of the
NIIYaF MGU (Scientific Research Institute of Nuclear Physics, Moscow State
'University) specially equipped for this purposel the experiments were made
at 200 cps. Fig. 2 shows the scheme of the chamber, the position of the
injector, and the probes in the branches. Tantalum plates, 15 x 30 mm large
and 0.5 mm thick were used as probes. In the present paper, the electron
flux density intercepted by one or the other probe is measured immediately
in the chamber in dependence on its radial position. Besides, also the
effect produced by the depth of each probe introduced into the chamber upon
the magnitude of the fluxes intercepted by other probes are studied with a
radial shift in the chamber (Figs. 3, 41 5). By means of the data obtained,

the distribution of the electron charge in the cross section of the beam,
and also the distribution of the beam in the chamber could be determined
during the first cycles. The electron beam emitted from the source during
radial osoillationsp periodically approaches the outeg chamber0wall, which
occurs in the 4th and 6th cycles, on the azimuths 135 and 225 , where the
probes nos. I and 3 were fastened. The experimental results obtained per-
mitted determination of the distribution of the charge over the cross
section of a separate beam. Fig. 6 shows the curve of the dependence of the
flux upon probe no- 3 during its shift from the outer to the inner wall of
the chamber. If a quantity be taken as beam width that corresponds to the
half-width of the differential curve concerned, it holds from Fig. 7 that
the radial dimensions of the beam do not exceed 10 mm. The authors thank
Professor V. A. Petukhov for discussing the results obtained. There are
