TEM A faBt-neutron spectrometer with a high gamma background is de-
scribed. The separation of the recoil proton and electron pulses is
based an the difference in the fluorescence time of the scintillator when
irradiated by heavy and light particles. It is known that several organic
scintillators ohow this difference in the fluorescence time when irradia:ted
by heavy particles (alpha particles and protons) and by electrons, This
time difference depends on the different ionization capability of the
heavy and light particles. There are more ionized molecules along the
track of a heavy parti cle in the sointillator than along that of an
electron. After about 10-9 sec the e3ccited molecules will return into
their normal state and the ionized ones after about 10-7 see. Therefore
the fluorescence will take place in two parts for both cases: viz. a

fast and slow part. The slow part caused by heavy particles will last
longer than that caused by light particles. Thereforey the mean
fluorescence time during irradiation of the scintillator by heavy particles
will be greater than that by light particles. The front of the current
pulse'in the photo-multiplier will also differ for both kinds of particles
viz. that caused by light particles will be steeper than that cau;ed by
the other particles. Stilbene crystals possess such properties. Pulses
of different shapes are produced if such a crystal is irradiated by.
neutrons and gamma rays, so that pulses of neutrons can be distinguished
on the background of gamma rays. Stilbene crystals possess such
properties. Fig. 1 shows a pulse discriminator, which is used in the
.spectrometer described,,,in connection with a stilbenelcrystal to determine
fast neutrons with oneipickup. Fig.3 shows a blockyfiagram of this
instrument. This faBt-neutron scintillati - poster is not sensitive
to a gamma background when irradiated by neutrons having an energy En)2Mev.

ABSTRACT: Removal cross sections for titanium were measured in a water-water reactorl
of the swimming pool type. Sheets of titanium measuring 70x7O cm were placed near tYe-
reactor core with dimensions of 50x43x32 cm. The removal cross section was determined
from the expression

barns. The removal cross sections determined for detectors with various effecti-ye
energy thresholds from 1.1 to 7 Mev coincide within the limits of experimental error.,
The minimum distance from the plate used for the removal cross section depends on the
effective thresh ld f th detector. For neutrons with an effective energy of 1.5 Mev

ABSTRACT: ' The.use of serpentine rook for biological shieldinAs dis-
cussed. This mineral is found widely distributed in the Urals, Caucasus
Siberia and Kazakhstan, usually associated with asbestos deposits such
as the Bazhenov quarries where pure BerpeAlnite monoliths of about 1 cu m
were excavated. Its bound water is liberated only at temperatures ex-
ceeding 4500 C. Thus it can be used as a heat-resisting material for
biological shielding. The concentration of hydrogen nuclei in serpen-
tite being about 1,5% by waight, is quite sufficient for insuring the
attenuation of fluxes compose'd of intermeCtate and fast neutrons. The
density of monolithic s9rpDntjatjb is about 2.6 ton/ou m while the thermal
cond,uctiTity varies between 2.16 and 2,56 kcal/M.hr, C. This material

~Ifine sand (from Bazhenov deposits) were tested in a water-cooled and
,water-moderated research reacior. The-boxes filled with sand were
placed close to the core vessel* The maximum thickness was about 180 cm
The sand density was 1.62 ton/cu M'. The chemical, composition given in a
table shows that the serpentite sand includes 38.83% of SiO2 and 37.39%
of'1%0. The investigations were carried out assumming "semi-infinite"
and "energy barrier" geometry. The method of induced activity was used
for determining the neutron flux attenuation, while the gamma dose rate
was measured by means of a scintillation dosimeter. The macroseopio
cross-section for fast neutrons in.sand was calculated as 0.0602 em-1
of-which 45% was due to oxygen and 21%-to hydrogen. The variations of
croas sections in serpentite and its main components for different
levels of.fast neutron energy was shown In a graph. The peaks and dips
in curves reflected the dependence of cross-seotions upon the presence
of oxygen, The attenuation of fast neutrons calculated on the ba81S Of
threshold measufii~ents is also graphically illustrated. From these
graphs and a table) it follows that the relaxation of neutron in serpen-
tite sand is the same--as in boron carbide* The protective properties of
Perpentite monolithloal blocks are considerably higher then those of
iron ore concentrates and only slightly better than those of serpenrAn-
ous concrete. The spectra of fast neutrons were also determined and the

Was also Investigated. A certain accumulation of neutrons was observed

neutrons was--the same for tested layer thicknesses, The dose relaxatiom
:was 15.2 cm* The gamm dose attenuation was 22 cm for a aerpentita
:layer of 2Y0 g/sq cm. The experiments showed that the serpentite sand
is as good as-the boron carbide. In conclusion, it was stated that the
'serpentite is not as good as the iron oft concentrate, although the-
raonolithic serpentite has a lower relaxation length. The serpentite

(Fig. la).and the spatial charge saturation method (Fig..Ib), respectively.
-As seen from Fig. la, Y-quanta at 1.33 Mev are not registered until the intensi-

found, however, that Yradiation with energies greater than 3 Mev is registered.
when the spatial charge saturation method is used in measurements on a nuclear

TITLE: Procedure for measuring the depth of modulation of light flux
SOURCE: Zhurnal prikladnoy spektroskopii, v. 5, no. 3, 1966, 284-28T
TOPIC TAGS: liaht modulation, luminescence, photoconductivity, Karr call
ABSTRACT: In view of the development of new types of modulators for use with re-
search on luminescence kinetics and photoconductivity, the authors describe apparatus,
aimed at comparing different modulators, for the measurement of the depth of modula-
tion of light flux from a light modulator or from a dource of modulated light. Thi-
principle of the apparatus (Fig. 1) is based on interrupting the light by a rotating
perforated disc and measuring the oscillograms of the output of photomultiplier on
which the interrupted light is incident. A Kerr cell was used as a standard mbdulator
producing a constant depth of light-flux modulation. The use of the Kerr cell made
it possible to correct the photomultiplier readings for inertia occurring at different-
frequencies. As an example illustration of the operation of the equipment, it was
used to measure the depth of modulation ofthe light flux from a neon lamp (type TF-
0.20) at 4 Mcs. Orig. art* has: 4 figures, 3 formulas and 1 table.

TITLE: On the Application of the Method of~Xeasuring Angles in Sets
PERIODICAL: Geodeziya i kartografiyap 19609 Nr 3, pp 21 - 25 (USSR)
TEXT; The present paper refers to an article by B. X. Rubio published in the
periodical "Geodesiya i kartografiyalls 1959, Nr 1. B. V. Rubio demands that the
application of the method of measuring angles in sets be prohibited for obser-
vations at triangulation points of the second orderg and that it should be
restricted at points of the third order. Based on the experience gained in the
Novosibirskoye AGP (Novosibirsk Aerogeodetio Enterprise) it is shown that
B. X. Rubis is wrong. The observers ff. F. Shiehayevj Yu. At Bykovj I* G* Dement.
yevt and N. As Dragovich are mentioned. For observations with changing eight
conditions in some directions the method suggested by N. V. Yakovlev (Ref 1,
footnote on p 23) is recommended. In order to confirm the arguments in favor of
this method Professors D. A. Kuleshov (Ref 2, footnote on p 24) and
X. L. Provorov and Docent A. A. Vizgin (Ref 2# footnote on p 24) are cited.
Based on the explanations made here the following is noted and suggested:
1) Vhen observing points of continuous triangulation nets by meant of the method
of measuring angles in sets the results obtained show the same accuracy as when
observing angles in all combinations. However, it saves timep and the successive

adjustment is simpler when applying the former method. 2) Experience gained
from setting up continuous triangulation note of the second and third order -
more than half the points of the second order and all points of the third order
being observed by the method of measuring angles in sets - showed that the ac-
curacy achieved met the demands of the mapping phase, 3) For setting up tri-
angulation nets the most economical methods must be used in order to prevent
superfluous work. On of the ways would be to apply to a large extent the method
of measuring angles in sets and the method of "incomplete observations" for ob-
servations at triangulation points of the second order- 4) The development of
new methods used to measure horizontal angles must be continuedl the solution
being found in uniting the method in all combinations with the method of mea-
suring angles in sets- 5) The question of reducing the number of observations
-to nine for observations of triangulation points of the third order should be
considered. There are I table and 3 Soviet references.

PERIODICAL: Geodeziya i kartografiya, 1959, Nr 5, pp 213-31 (USSR)
kB STRACT: The paper under consideration presents a number of remarks on
the method and the devices employed in reconnaigsance. As a
rule, two main operations are carried out in the reconnaissance
of the trian6ulntion note of the 2nd and 3rd orders according
to the maps drawn on a scale of 1 : 100000 - accurate
identification of the zone for the projected point in the
terrain, and the determination of the elevation of the control
point. The Novosibirskoye aerogeodezicheskoye predpriyatiye
(NAGP)(IlovosibiTsk AerogeoSetic Enterprise) employ the
procedure proposed by the author. In open or closed flat
terrains this procedure-facilitatds with sufficient accuracy
the immediate reaching,Qf the zone of the projected station
along the mapped-out ro'uite, vast and deep bogs being avoided,

bog terrain, where the author carried out work, is called
"urman" by the population. On the boggy ground of the urman
progress'is difficu '~X' even for horses carrying burdens of
only 30-40 kg. Almost always two horses are required per man.
The highest tre'e clusters consist of aspen trees, which are
v-jry brittlo, thus rendorin-v difficult the erection of masts
on these trees. In-open and flat terrain the djetance is
determined by thQ number of wheel revolutions in vehicles or
cars by means of a speedometer. A cyclometer ("odometrl-) is
recommended for the Soviet Far North. Some remarks are
Dresented on the erection of masts and on reconnaissance from
masts or tree-tops. - The use in reconnaissance of periscopes
of the type of the artillery mast periscope seems desirable.
These periscopes would render superfluous the climbing of
masts and eliminate the dangers involved. Besides, women
could then also be employed in reconnaissance. There are
5 Soviet references.

The means of lifting masts and poles on trees is suggested. For this
Inethod., only three workers are needed. It is also suggested that the man
Getting the reference points use metallic insertion stairs instead of wooden
leads, and to fix the span rope, that he use clamps in the form of a chain
,with a semiautomatic closure. The computation of the strength of the lift-
rope levers, and turning axis is presented. (U)

TEXT: A block diagram of the instrument is shown in
Fig. 1. The signals from pick-ups 1 and 2 , which are
proportional to the current and voltage amplitude (in the
right phase) are applied to the voltage dividers 3 and 4
The latter are used for attenuating the signals to the
required level necessary for the operation of the converter 5
When the input signals are applied to the converter,,a
constant amplitude pulse is obtained at its output, the pulse
being proportional to the instantaneous active power across the
measured load. The peak value of the pulse is recorded by
the memory device 6 and is measured by the DC vacuum tube
voltmeter 7 . The cor--recting network 8 is employed for the V~
correction of the measurement error of the converter. A
calibration generator 9 is used for checking the Instrument
