TEXT: Two new types of photoelectronic multipliers PY-35 (FEU-35) and
~)Y-29 (FEU-29), as applied to scintillation spectro6ters, were worked
out by the authors. Full particulars are given of FEU-35, less of
FEU-29. The cathode diameter of FEU-35 is 25 and 34 mm for 108 mm length.
To improve electron-optical properties of the input a focusing cylinder
(of. Fig.1) is applied. This cylinder permits better combination between
the axial-symmetric inlet of the multiplier and the inevitably asymmet-
rical first cascade of the multiplier system. The new inlet system
secures a good energy resolution. As much as 600 FEU-35 devices were
checked for amplitude resolution (Fig.2) and for the amount of the
energetic noise equivalent (Fig.3j. Fig-4 illustrates the average

pendence of the dark current on the supply voltage.'The linear depen-
dence of the output signal amplitude on the y-quantum energy is secured
up to amplitudes of the magnitude 10 v for 50 k92 and 10 pF. The sensi-
tivity threshold is about (6-8)-1o-12 lm for a resonance amplifier band
width of 20 cycles and for a resonance frequency of 80 cycles. The
second multiplier (FEU-29) suitable for y-spectrometry has a cathode
with the dimensions 38-48-190 mm. Its amplitude resolution is given
with 7.5 - I(YI.. it exhibits an especially low noise level (1 - 2 kev)

TEXT: This paper was presonted'at the 9th All-Union Conference on
Cathode Electronics, Moscow, October 1959.
The stability,of the output signal from a photo-electron
multiplier depends on a number of factorsi the voltage, the
current, the time of operation*and so on. The purpose of this-
article in to clarify the effects of these factors on multipliers
with emitters of different materials. Since multipliers are
widely used an scintillation counters, the multipliers were tested
in a special set-up which approximated to oserational'conditions
with crystals of NaJ(TI) irradiated by Cal 7 on the cathodes of
the multipliers. Block diagrams of the test apparatus are given
and the apparatus is described'. The output current, which
depends not only on the amplitudi but also on the frequency of the
Card 1A _z:-

pulsess i.e. on the intensity of irradiation of the crystal by
y-rays, was also monitored. The results show that there are two
types of instabilitys 1) smooth change in the average value of the
amplitude of the pulses over a period of time and 2) oscillation
of the amplitude about a mean value, which shows as a scatter of
the recorded points for a given curve. The deviation of the
points is approximately 0,3 to 1% of the value of the output pulse.
Early tests showed that the stability depended to a great extent
on the previous history of the multiplier. The "settling-down"
time in different for different specimens and'for the same
specimen the settling-down time on the first day can be very much
longer than on following days. This "training effect" made
investigation of individual specimens impossible and statistical
tests on a number of multipliers were necoaxaryo The results on
80 multipliers of the 403Y-35 (FRU-35) type with Sb-Cs cathodes
and emitters are presented graphically by histograms of percentage
change in pulse amplitude against numbers of multipliers for output
currents of 0.1 to 2.5 microamps, 0,3 to 0.5 microamps and
0-55 to 6.0 microampo. The maxima of these distributions show

greater percentage change for larger currents. The results for
60 antimony-cosium cathode and emitter multipliers were similar.
It is concluded that during the first hours of operation the
stability is directly related to the output current and reduction
in the current density improves the stability. The absolute
maxima of the changes in the output current of the multipliers did
not exceed published figures for multipliers with Al-Mg, silver-
magnesium and antimony-cesium emitters. The settling-down time
was found to be proportional to the output current. Testar on
multipliers 1#3W-24 (FZU-24) with aluminium-magnesium alloy
emmiters showed'that they also have, appreciable settling-down time,
but the output current has little effect on it, except that it is
reduced with high currents. For example, a batch of multipliers
with Al-Mg emitters and bismuth-silver-cosium cathodes had an'
average settling-down time of 10 to 20 min, after's rest-poriod
of 12 hours with output currents of 20 to 30 microamps. To
clarify the effect of activation by cesium on the stability of
alloy emitters, a multiplier with a thermo-cathode was prepared.
The stability of the emitter was chocked directly in a vacuum with
continuous pumping before and after cesiation. The relative

changes in the secondary emission coefficient for thermo-
activation and for cesiation, for one stage of a copper-beryllium
alloy with 100,V and 0.3 mA output current are shown graphically.
It in seen that the presence of cesium leads to an increase in
both the nettling-down time and also in the magnitude of the change
in the secondary emission coefficient. There are 7 figures and

TM: A new method is proposed for solving problems of electrical simula-
tion of movable frames. The method is based on the application of well-known in
their mechanics approximate methods of analysis for the preliminary determinati(n~
of the displacement of the frame nodes with the subsequent introduation of these
nodes into the electrical simulation circuit in the form of emf imitating the
angles of Intersection of the struts. The proposed methed is Illustrated by ex-
amples of analysis of single-level plane multi-span frames with varied strut at-
tachment; by the simulation of monotonic symmetrical multi-level, multi-span, i
frames bearing a wind load, and-by the simulation of plane movable multi-level

ABSTRACT: In the present paper experimental data on the electric double
refraction in polystyrene solutions are given. The solutions
of 7 polystyrene fractions were investigated. Carbon tetra-
chloride served as rlvent. As the experiments showed the
dependence A = f (E ) remains linear in the domain of the
concentrations used. The Kerr constant was computed for all
measured polystyrene fractions according to the diagram A
versus E2 (Table 1). For reasons of comparison the Kerr
constant of styrene (Table 2) was ascertained too. The Kerr
constant of the solutionj of various polystyrene fractions
(molecular weight 4.0-10 500.106) is,evidently,within

constant of styrene. The behavior of the polystyrene solu-
tions in a constant electric field is analogous to their be-
havior in a magnetic field (Refs 2, 3). As a comparison the
molecular Kerr constant of benzene was examined. Measuring
m3ults of this constant in carbon tetrachloride at various
concentrations are given in table 2. The quantities K 2 for
styrene and benzene were determined from the diagram plot-
ting K12 versus C 2* The coefficient of the angular de-
pendence K12 - f (C2) permits to determine the quantity K 2
for infinite dissolution. The computation showed that the
molecular Kerr constant of styrenes is by about two times
higher than that of benzene. It was found that the Kerr
constant of the polystyrene is independent of the molecular
weight. Its sign is positive and in its magnitude it r3-
sembles the Kerr constant of styrene. These facts prove
the conclusions made by the authors (Refs 2, 3, 7). The
authors exprees"their gratitude to V. N. Tsvetkov for his
interest. Ther6 are 2 -4igures, 2 tables, and 7 references,

ABSTRACT: The dispersion of sound velocity in hard metals predicted
by R. A. Alpher and R. I. Rubin (Ref 1) has hitherto not
been observed, apparently because of the smallness of the
effect. The present report describes experiments conneeted
with the discovery of this phenomenon. An apparatus was
developed and built for the investigation of slight varia-
tions of the sound vibrations which, in the case of favorable
condit'ons. takes it possible to measure relative deviations
of about '10- from sound velocity. The principle of the
measurements is based on the comparison and the measuring of
the phase difference of the vibrations passing through the
sample to be investigated. The block scheme of the measuring
apparatus is shown by a diagram. The high frequency voltage

ia transferred to the radiating quartz which on one side wao
stuck on to the cylindrical aample, The receiving quartz is
then stuck on to the second front face of the samplev and
the voltage produced by it is then transferred to a phase-
meter. At the same time a voltage is directly transferred
to the phasemeter from the radiating crystal. For the investi-
gation of the ultrasonic vibrations quartz plates (x.--seotion)
of a diameter of lo mm were used. Cylindrical rods of a
length of 2o cm and a thickness of 14 cm served as samples.
A diagram shows the results of these experiments, which were
carried out at room temperature in a field vertical to the
axis of the sample. The experimental points fit well on the
theoretically calculated straight lines. Sound velocity thus
in--,reases proportionally to H in the magnetic field and
the intensity of the effeot corresponds to the predictions
of theory. It is interesting to learn that in bismuth no dis-
persion of the sound velocity was observed at room temperature.
Finallyv the authors thanked Professor A. I. Akhiyezer and

ABSTRACT: It has already been shown that for longitudinal sound the
absorption coefficient in tin depends on the ma~,-netic field
in ouch a manner, that if the latter is vertical to the wave
vector, a weakly marked maximum of absorption occurs in
certain fields; a similar phenomenon is observed in poly-
crystalline copper and in indium. In the present "Letter to
the Editor" experiments are discussed in which the influence
exercised by the magnetic f5eld on the absorption of ultrasonics
at low temperatures in polycrystalline samples of very pure
metals was investigated. Tin with a rosidual resistance
1 1.6.10-5 and zinc with R 4.2/R300 ~ 2.10-4 was investigated.
The samples had a diameter of 12 and a length of 12 and 15 mm
Card 1/3 respectively. The absorption coefficients were determined by

obtained by measurements r;arried out at 4.20 K with a magnetic
field that was vertical to the wave vector. The curves plotted
at higher frequencies show already two maxima, Thusj zinc at
70 megacycles showed a minimum at about 500 Oe, the first
maximum at about 800, and a second flat maximum at about
2,000 Oe. If the magnetic field rotates in a plane that is
vertical to the SaMDle axis, the curves are found to va-ry
essentially-, The absorption of the maxima and their amount
varies~ in the case of certain directions these maxima vanish~
and in certain cases the maxima exist only within range of the
angles of 15-200. Figures 2 and 3 show such diat;rams at
70 megacycles. Here the absorption coefficient for ultra-
sonics shows a tendency of assuming a saturation value at
5,ooo-6,ooo Oe. This limiting value depends on the orienta-
tion of the sample in the field. The diagrams for the limiting
value in the case of stron.-, fields describe the anisotropy
of electric conductivity in the magnetic field, There arc 3

ABSTRACT: It has already been shown (Refs 1-3) that the absorption coef-
ficient of ultrasonics in metal does not change monotonely with
the m W etic field, but that it has a special anisotropy. The
authors of the present "Letter to the Editor" investigate the
latter at an ultrasonic frequency of 70 megacycles and give a
report on the results obtained. Investigations were carried out
in a spherical monocrystalline lead sample Of 15 mm diameter.
Planes were out off from the sphere, to which the ultrasonic
sources were applied. The perpendicular lines of theme planes
were parallel to the axon of 2. and 4- order. Absorption was in-
vestigated for longitudinal sound, the wave vector k of which
was parallel to the axis of 2. or 4. order. The sample was ro-

the relation ae Van =2/(e Eo/kT + 1). To investigate the influence of the
lattice anisotropy on the energy spectrum of electrons in a semiconduc-
tor, the temperature dependence and absorption coefficients of longi-
tudinal supersonics was investigated by means of an apparatus described
here in detail. Fig. I shows a block diagram of the measuring device.
The generator works at 70 Me/see, the quartz emitter receiv9s
2500-3000 pulses per second for a duration of (1 1-1-5)-10- sec. A small
sphere of single crystals of tin was used as a sample. It had a diameter
of 13-15 mm, and on it, cut surfaces of 5-6 mm diameter perpendicular
to the crystallographic axes were produced by electrocorrosion. Onto
these surfaces quartz emitters and receivers were cemented in vacuum
and on them small plates of brass of 5-6 mm diameter and a thickness of
0.2-0.3 mm. For very pure crystals of tin the condition that the mean
free path of the electrons be large in comparison to the ultrasonic
wavelength was very well fulfilled at helium temperature. The temperature
dependence of ultrasonic absorption coefficients was measured simultane-
ously in two different directions at temperatures down to 10K. Fig. 2
shows the Dewar for helium in which the measurements were carried out.

The temperature of the sample was determined from the saturation vapor
pressure of helium. The results are shown in diagrams. Fig. 3 shows
lxs/c~n between 10 and 40K taken along two mutually perpendicular C2 axes.
The measured values (full and empty circles) all lie on one line which
shows that the physical properties are the same in the two directions.
Fig. 4 shows the same for C. and C 4 axes. Here the anisotropy of the
energy gap is clearly seen. ieasurements made on two samples gave uniform
results. For the absolute value of the electronic part of the ultrasonic
absorption coefficients in the normal state in the neighborhood of T.9
the following results are obtainedt(Xn - (47.6 + 0.2) decibel/cm -(C.),

From the slope of the straight line portion of the curve, the energy gap
width at absolute zero may be determined to be (3-5 � 0.2)kT a for the

For tin- and indium crystals typical oscillation diagrams are shown and
,liscussed. Two different types of oscillations are said to occur in tin:
Anharmonic resonance oscillations and sinusoidal oscillations. Those of
the first kind are ascribed to the existence of an open Fermi surface;
the period of the open surface, calculated on the basis of oscillation
periods, is in agreement with crystallographic data. A study was made of
the anisotropy of ultrasonic absorption in a strong magnetic field and
when the condition r
