ABSTRACTt At present the production and delivery of some new
photoelectron-
-multipliers (FEV) worked out by the authors were begun on an in-
dustrial scale. They are shortly described here. 1.) The production
of the special multiplier for the scintillation-svectrometers
~P 3 Y -29 was recently begun. It has a good amplitude-disablving
power which is guaranteed by the comparatively high sensitivity of
the cathodes of 1the device. The integral sensitivity is higher
than 30,u A lm- on the average 40 - 45 p A lm-', the "blue" one
is higher than 6 A m1-1 which corresponds to a quantum discharge
of more than 9 % at X ~-,i 4000 R . Besides the electron-optics
at the entrance of the multiplier guarantees a good taking over
of the electrons from the cathode to the dynode, as well as mini-
mum losses in the first cascades. The amMtude of the noise, mea-

1-level, is not hif.,,her than 5 * 8 keV. The light-cha-
impulse sea- 0
racteristic is linear up to the am litude of the initial impulse
7 - 8 V at a load of about 50 k B and a parasitic capacity of
\< 1OpFj with the method of operation given in-the pass filter
of the device. The most important operation-parameter of any FEV
is
the stability. Most of the (~ 9Y -29 under the usual conditions
in the gamma-apoctrometers work sufficiently stkle. Experiments
with dynodes of different alloys are now made for improving the
stability. At the same time thqinfluence of technological factors
and the construction of trnodes upon the stability of the FEV is
also experimentally investigated.
2.)FEV vrith enlarged cathode. According to the preliminary data
these multipliers have the following average static parameterst
integral sensitivity of the cathode 35 - 40)u A 1m-1- th "blue"
sensitivity - 7,Ax A 1m-1. Amplification about (2 + 5) .109 at
full
voltage of 1400 - 1500 V. At much higher voltages it can attain
1o7. The density of tit heat flow from the cathode on the averaze
amounts to 5-lo-15 Acm-2.
3.) "Time"-FEV. Beside the "general" parameters the minimum scat-
tering accordine to the time of passage of the "electron-parcel',
through the multiplier in the case of a maximum steep front of the
Card 2/4 initial impulse is also demanded of it. After the
modelling of many

New Industrial Types .of Photooleatron Multipliers 413-12-15/15
variants a system was found which guarantees good focusing of the
electrons and minimur. scattering of the time of flight. The cal-
culations of the maximum time-of-flight gradient in this multi-
plier system with grid yielded a quantity of 4,4.10-10 Sec (at a
voltage of 100 V/cascade) which is 3 - 4 times less than tn the
multiPlier-SYstem E4646.(reference 3).
4.) The beat ratio of the signal to t1m background in the wave-
-range of 5500 to 8000 1 is given by the bismuth-silver-cesium
ca-
thodes. The experimental samples of multipliers with such
cathodes
are produced in two sizest that of the CI)DY -29 and in a smaller
size. The multipliers have 11 cascades. Their integral
sensitivity
of the cathodes on the average is 45 50 A Im-1. 'The amplifica-
tion is of the order of magnitude 105 lot at a full supply-vol-
tage of 1400 - 1600 V. The smaller multiplier is distinguished by
a great Vibration-strength.
5-) The miniature-FEV. At present a construction was worked out
for an eight-cascade-miniature-multipliet (~ 3,Y whose outside
diameter is greater than 22,5 mm and whose heiRht is 65 mm
without
peg. The flat, semi-transparent cathode of antimony-cesium has a
Card 3/4 working diameter of 18 mm. Its sensitivity is below 25
p A 1m-1.

ABSTRACT: The multiplier is fitted with an anti mony-caesium cathode,
which is suitable for the operation with light beams having
a diameter of about 2 mm. The emitters are also Sb-Cs-coated
and are constructed in the shape of a box (see Fig.2a). There
are ? emitters and a special anode which is in the form of a
grid, parallel to the surface of the last emitter (see Fig.26).
Dimensions of the multiplier are 58 mm in height.' and 22 mm in:
diameter. Overall sensitWty of the multipliers was measured
at a light flux of 3 x 10- Lm and the sensitiviTy of the
cathodes was investigated at 3 x io-5 Lml the diameter of the
light beam being 2.15 mm in each case. Results of the measure-
ments on 20 laboratory samples of the photo-multiplier are
shown in Table 1 on p.423. It was found that the average
cathode sensitivity was 28 )iA/Lm. This'was thought to be
satisfactory for most practical applications. The average
Cardl/3 amplification of the photo multipliers was 105 at the overall

109-3-15/23

supply voltage of goo V; the voltage per stage was thus 113 V
and the amplification 5.2. If t e overall voltage was 800 V~
a total amplification was 5 x 1A. Voltage current character-
istics of the multipliers were also measured and two typical
curves are shown in Fig.4; Curve M represents the overall
amplification as a'function of the inter-stage voltage, while
Curve IT represents the dark current as a function of the
voltage. iioise and threshold sensitivity of the 20 samples
were also measured and the results are reported in Table 2 on
p.424; the threshold sensitivity, as a function of the voltage
per stage, is shown in Fig-5. Anode characteristics of the
multipliers for two different valuas of the output current are
given in Fig.6. The construction of the multiplier is such
that the anode current is dependent on the position of the
light spot on the surface of the cathode. It was of interest,
therefore, to investigate this effect. A beam having a diameter
of 1.05 mm was used for the purpose and the sensitivity curves
obtained by this means are shown in Fig.?. It is seen that
the edge portions of the cathode have the highest sensitivity.
This effect is thought to be due to the presende of two angles
Card2/tt the edges of the cathode. This was confirmed by the
fact

109-3-15/23
A Miniature Photo-electron Multiplier with a Bulky Cathode
that, if, an add-itional.angle (threshold) vi-as placed in the
middle of-the cathodei the sensitivity had an additional
maximum in the oentre of the cathode. On the basis of Figs.
7 and 8, it is concluded that the reason for the increased
sensitivity of the cathode in the regions close to the angles
is the focusing of the photo-electrons on to that portion of
the first emitter which directs the highest possible number
of the electrons on to the second emitter.

A13STRACT: In the diode system of the Soviet multiplier Xiii bent
grid is mounted in front of each diode which serves as an
additional accelerating electrode. The new multiplier type is
given the trade nark:7W,.:-31. The accelerating grids decrease
the difference of the time of the flight of the secondary
electrons between the diodes which is conditioned by the
different initial velocities of the electrons. At theMMtb2the
multiplier can take hialier current leads. The arids which are
placed in front of the i-th diode are connected with the
(i + 2)-th diode.
The diodes have a semicircular bo,.,,, rh ends in two strai6-ht

gures and 4 references, 2 of which are Soviet.

ABSTRACT: In the conference (Ref 1) last year preliminary data
on the
new 13-cascade, multiplier (FEU -photoelectronic multiplier
FEM) were communicated. This' ae;rice serves for the
investigation
of nuclear Drocesses with a Faso sequence. The investigations
of the parameters and of the characteristi3a of the PER-33
recently carried out 'by the autho:,s yielded the following
results: according to the techniual as5umptions the integral
sensitivity of the cathodes of the FEM-33 as well as of the
FEM-29 should not be below 30 'tkA lm-l~ The mean integral
sensitivity of the multiplier cathode which was developed in
Card 1/3 the last two months amounted tf,~ 404 A Im-1 . The

of the PM-33 are giyen in figure 2 (continuous curyes). For
comparison the characteristics of three 14-cascade multipliers
RCA-6810 are given with dotted lines, These curves were taken
under the same conditions. Measurements of the amplitude re-
solution of the FEM-33 showed that it is by no means inferior
to other FEM's. The noise leyel of the FEM-33 according to the
scale of the NaJ-(Tl)-Csl37 is of the order 3 -- 4 keY (at *a
counting rate of 50 Pulses per sec). The classification 0-e'

specimens of FEM-33 according to the pulsed output current is
given in figure 3. The weakest oarrents equaled 0,3 As the
highest about 1 A. InTestigations of the I-inearity of the
output currents at a voltage of the order of 4 kV showed that
on the average the FEM-33 operate linearly up to 0,5 A. The
deviations range from OP4 to 0,8 A (Fig 8). The width of the

TEXT: A description is given of a method of measuring the time
resolution of photomultipliers using a fast oscillograph and
periodic
light flashes of nanosecond duration. The oscillograph employed
was
described by Pollskiy in Ref.1 and the light flashes were
obtained by
spark discharge. The flash repetition frequency was adjusted to a
few hundreds of kc/s and the time base of the oscillograph was
V
triggered by synchronizing pulses from the flash generator, For
each
photomultiplier optimum supply conditions were first determined,
giving rise to the maximum pulse amplitude. The slope of the
leading
edge of anode pulses. S and the amplitude of the pulses were
measured. The length of the leading edge was defined as the
10%-90%
rise. The slope S was defined as the amplitude of the pulse
divided by the length of the leading edge (in units of
mA/nanosec).
Thirty �V -33 (FEU-33) photomultipliers were investigated. The

maximum value of S was found to be 350 mA/nanosec. Other photo-
multipliers tested were two FEU-11 (S = 20 and 1.00 mA/nanosec,
respectively), one FEU-13 (S = 150-200 mA/nanosec) and RCA 6810A
(S = 200 mA/nanosec). In the case of the FEU-33 photomultipliers,
the amplitude was found to lie between O-3,and 1.1 A and in 75% of
them the amplitudes were between 0.4 and 0.8 ~A. The output pulse
amplitudes for the other photomultipliers were roughly within the
same limits. The measured pulse length t (measured at the base
of the pulse) was found to be: 20 nanosee (Ftu-33), 100 nanosec
(FEU-11), 40 nanosec (FEU-13), 30 nanosec (RCA-6810A), 20 nanosec
(RCA-6342) and 6-9 nanosec (special photomultiplier with time
spread compensation). In the latter case the leading edge slope
was found to be 400 mA/nanosee on the average. The spread in the
transit times of photoelectrons was measured by illuminating the
central part of the cathode (diameter 5 min) and thenusing special
screens with narrow annular apertures, the peripheral parts of the
cathode. The results obtained for the time spread are summarised

To improve electron-optical properties of the input a

(of. Fig-1) is applied. This cylinder permits better
combination between
the axial-symmetric inlet of the multiplier and the

TEXT: The article under review was read at the Tenth All-Union
Confer-
ence of Nuclear SpectroscEU (Moscow, January 19 --17, 1960). The
dependence of the amplifioavion of photomultiElierd'Pon the
mode of pulse
operation leads to considerable difficulties in the case of
certain
energy measurements, In order to be able to estimate the errors
arising
within a large range of the counting ratep the authors
developed a
special apparatus to be used for the investigation of
photomultipliere
(above all, such of the type FEU-33)- Fig. I shows the

pulses. FEU-33
had a recovery time 1639 which was between 15 and 20peec in the
case of
RSA multipliers. The sane instrument also served to investigate
the

TEXT: In the present article the authors presel%t certain
analyti-
cal and experimental data on the electron optical properties of
photomultipliers. The authors state that in their opinion "ke
elec-
tron optical (focusing) properties of a system in Fig. I are
deter-
mined by two dimensionless parameters p = D/d and q = D/hf where
D - the diameter of the cup; d - diameter of the photoelectron
beam
in the plane of diaphragm (thediameter of the input window of the
diaphragm); h - distance between the plane of the cathode and
that
of the diaphragm. In designing a photomultiplier, p, and hence q.
is given. The function p = f(q) can be determined from an

TITLE: The transfer of radiation in a plane parallel layer
in the approximation of nonlinear optics
PERIODICAL: Optika i spolctroskopiya, v.12, no.4, 1962, 533-536
TEXT: The problem of the transfer of radiation in a plane
parallel layer is considered on the basis of equations for them
transmission of radiant energy with a nonlinear dependence of the
absorption coefficient for dense radiation. The calculations are
for monochromatic radiation (flux So ) propagated normal to the
surface of a layer of thickness 6. On account of multiple
reflections between the boundary layers there will be two fluxes
S, and S2 in opposite directions at any point x in the layer.
An expression for the absorption coefficient k is derived

light field and a the nonlinear parameter (a ~,O). The problem
is only considered for a particular case which allows an easy
analytical solution, namely by putting So equal to zero.
Equations are derived for the change in value of the absorption
coefficient with position in the layer and its dependence on
the reflectivity of the surface. The effect of a supplementary
field of density um due to the thermal background is also
considered and equations derived for the absorption coefficient k

TEXT: The subject of investigation is a plate of thickness-1 and of
small
luminance characterized by the absorption coefficient k and the

perpendicularly. Owing to.multiple reflection there'exist internally
two
kinds of flux at anypoint x;S I moving parallel to the incident
flux.and
S2 moving in the.opposite direction. These are described by the
differential equations dS I -kSIdx, dS2 - kS 2dx (1) with the boundary
conditions S I(X-o) 8 S6 (1 r) + rs 2(x-6)' 82(x-1 - rS 1(x-1) (2).
