TITLE: A Scintillation Spectrometer for Past Neutrons with
a Boron-containing Organic Scintillator
PERIODICAL: Pribory i takhnika skaperimenta, 1961, No. 3,
pp. 49 - 51
TEXT: The principle of the instrument is as
follows A fast neutron entering a scintillator may
produce a number of recoil protons as a regult of multiple
scattering ( in a time of the order of 10 see). Having been
slowed down to less than .10 keV,,it is captured by B 10 nuclej..
The capture is accompanied by the emission of an a-particle
which gives rise to a second pulse (on the average 2.2 jLs
after the first pulse). Using the delayed coincidence technique
and the amplitude analysis of the pulses, one can determine the
energy of the incident neutrons. In the arrangement employed
by the present authors, pulses from the anode of a photo-

multiplier are amplified and then fad into the "alpha" and
11proton" channels. The pulses in the proton channel are, on
the average, delayed by 2.2 lis. Pulses from the output of the
coincidence circuit, which are due to coincidences between the
11alphall and "proton" channel pulses trigger a univibrator which
produces a 100 V output pulse. This pulse is-used as the gating
pulse for a kicksorter (AM-100-1 (AI-100-1)). At the same time,
the pulses taken from the eighth dynode of the photomultiplier
are amplified and amplitude-analyzed. The scintillators
employed were:
1) P-terphenyl plus o-xylol plus trimethylborate (d = 4 cm;
h 4 cm);
2) p-terphenyl plus tolmol. plus trimethylborate (d = h 8 cm).
The authors carried out a theoretical calculation of the
efficiency of the spectrometer, assuming that in each i-th
scattering the energy of the neutron in reduced to
Ei+1 ~, Eiexp(-V, where is the average logarithmic energy
loss. The neutron-slowing-down time was taken into

account (elastic scattering with C and H nuclei). In the':-.*.
calculation, the cylindrical scintillator was replaced by an'.~'
equal sphere, beginning with the second scattering. The
computed efficiency curves were found to be in good agreement
with experimental data (N.A. Vlasov - Neutrons, 1955,
Gostekhizdat). The major advantage of the spectrometer is the
relatively high efficiency. Fig. 1 shows the efficiency as a
function of neutron energy (MeV). The two curves refer to the
two phosphors mentioned above. The efficiency for Curve I is
multiplied in the figure by a factor of 3- The efficiency at
15, 8.65 and 4.65 MeV on this curve is 0.12, 0.60 and 2.2396.
A disadvantage of the spectrometer is the relatively low
resolution and a considerable spurious coincidence background.
A preliminary description of this apparatus was given by the
first of the present authors et al in Ref. 3 (PeredNoy nauchno-
tekhnicheskly i proizvodstvennyy opyt, No. P-58-i6l/7). It
was developed during the period 1957-1958 at the Moscow
Engineering Physics Institute.

contribute to the dose: (1) thermal neutrons with E) 1 ev; (21 1plow
neutrons with I ev < E < 100 ev; (3) intermediate neutrons with 100 ev < 9

and meth.,11,no.l 144,1961; Aronson at al. US AFO,Rcp.NYO-6269y1954)-
An analysis of the curves obtained shows that the fast neutrons oobtrI.-
bute most to the dose - e.g. at r-90 cm tile doge due to the fast flux
is ten times as great as the dose due to the intermediate flux, And 100
times that of the sloii neutrons., The dose spectra obtained similarly for.
carbon show that for thicknesses ',~ 50-6o g/c~2 virtually the whole dose
is due to thermal neutrons; in lebs thick ehielde fast neutrons also
make a significant contribution. The done speotra for concrete show
that concrete behaves more like water than like carbon. The low-energy
groups, however, differ leas from the fast component than in water. The
main groups are, therefore: for water - the fast, for carbon - the therm;
for concrete - the fast, intoxmediate and thermal, and for iron - tho-
intermediate group (D.*Wpod, NAol.Soi.Engng.,5,45,1959). Thare are'7

ABSnACT: The basic characteristirts of neutron sources in the (a,n) reaction are
given. Nomographs for calculating a water shield from isotropic neutron p8int
sources are drawn. Four types of nomographs are plotted according to the design
of a 7 radiation shield. The authors claim that the calculated nomographs are
correct for an infinite water medium. A paraffin shield can be of 1.2 times less
thickness than the water shield, defined by the nomographs. In conclusion, the
authors point out that neutron radiation accompanies the source 7 radiation. There-
fore, the suitability of the selected water or paraffin thidness must be checked
from the viewpoint of protection against 7 radiation. Analytic results dictate

SOURCE: Voprosy* dozimetrii i zashchity* at izlucheniy, no. 2, 1963, 137-139
TOPIC TAGS: neutron, shield, albedo, fission neutron, neutron delay, delay density
ABSTRACT: The author claims that an analysis of the formula proposed by Prais,
Kharton, and Spinni (Zashchita ot yaderny*kh izlucheniy. M., Izd-vo inostr. lit.,
1959) for calculating the albedo of a delaying medium is only partially valid.
According to the author, it is no less important to obtain data on the spectrum of
neutrons reflected from a protective barrier. Assuming that a flat barrier is bom-
barded by a parallel, continuous flux of neutrons, the author arrived on a formula
which expresses the delay density at a point on the barrier boundary. The calcula-
tions are shown in graphs. The graphs are for three media, graphite, concrete, and
water. In conclusion, the author claims that graphite gives the least reflection,
but the spectrum is the hardesto The albedo spectrum in the intermediate region
is more rigid than the spectrum in the same region of the directly passed neutron
radiation. With an increase of lethargy, the thickness of the "Illuminating layer"

increases. The error of this method by analogy with the directly passed radiation
does not exceed 30%. Orig. art. has: .2 figures and 2 formulas.

ABSTRACT: An attempt is made in this paper to determine the amount of shielding
during the calculation of the spectrum of delayed neutrons, for protective means of
graphite, water, and concrete. Based on a mathematical argument derived from the
erf-function, the author constructed a formula for the calculation of apectral dis-
tribution of intermediate neutrons. A homogeneous medium with a constant scatter-.
ing croes section is assumed in the formula. Based on this formula, the author
plotted a graph showing the delay density of neutrons of a constant source (fig. 1).
The region from 0 to 9 on the lethargy Bcale is studied. In the case of large
shield thicknesses in the soft region of the spectrum, the age theory minimizes the
value of the flow by 30% (data was standardized at E 0.33 MeV). Orig. art. has:

TOPIC TAGS: proportional counter, response time, BF , neutron spectrum, SNM-5,

ABSTRACT: The use of proportional counters in installations connected with time
interval measurements can lead to substantial errors in the impulse delay at the
output of the counter relative to the moment of registration. In order to correct
this situation, the authors conducted a number of experiments using a counter of
the SNK-5 type filled with boron trifluoride to a pressure of 250 = Hg, cathode
diameter 3.5 cm, and an anode filament of 0.005 cm. The time necessary for the
electrons to drift to the filament also determines the delay time (Jitter). The
experimental installation is given in a block diagram. The width of the analyzer
window is selected so as to include the pulse amplitude region, which corresponds
to the photo peak and the Compton peak. The schematic of a single channel
differential analyzer with a stable response time is given. An increase in the

length of delay with the increase of voltage on the counter, as well as the change',
of the distribution shape are found. The authors determined magnitude of the
electron mobility in BF to be equal to 1.0 X 105. The obtained jitter pattern

determines the proper resolution of spectrometers in transit time with boron
counters and allows the corresponding processing of the spectra to be introduced.

ABSTRACT: Neutrons generated as a result of a photonuclear reaction in a urani-
um target and passing through a collimating channel 3 meters long and 20 cm. in
diameter came into contact with a shielding barrier in their path. The distance
from the bixrrier to the point of observation was 7. 2 meters. Types SNM- 0- 5
and SNM-8 counters were used as detectors. The time distribution of the impuls-
es was studied with a variation of a type Al- 100 analyzer. The flight'of the 1feu-'
trons had an equal probability *within the time Interval from 0 to 0. 5 microsec-
onds. The form in time of the lines of the boron counters is explained by the

finite nature of the diffusion time of the electrons toward the region of collision
1 ionization, and depends on the dimensions of the couriers, gas pressure, applied
z voltage, and level of discrimination, Since theoretical prediction of. the form of
the lines Is difficult, they were determined experimentally. The article derives
an integral equation for the instrument spectrum and goes on to give details of
three approximate methods for its solution. These methods are 1) the method
of polygonal expansions Involving the use of matrices;.2) a method analogous
to the method of counter efficiency; and, 3) a method of analyzing the instrument
spectrum based on complete resolution of the system. It is claimed that t 'he a-
bove methods are especially valuable for the case of radiation with neutrons* with
short flight times. Orig. art4 has:.. 7 formulas and 6 figures

termined Pcom a standard formulao The spectral distribution of the fast neutrons
was measured-with a alMle-ex7stal neutron spectrometerp and the Intermediate
neutrons were counted with a paraffin-imbedded fast-neutron counter. The results

nuclear power plant. It is assumed that the scheme, the materials, and
the type of plant are chosen first, and that the problem is then reduced
to fihding the values of the optimum conditions for the structural and
workin6 parameters of the plant. The minimum costs of electric energy
are determined from the condition that the partial derivatives of the
costs with respect to the independent parameters xk have to vanish:

dependence of costs on the weight of the plant, and considering that the

the surface of I kg of fuel element, the following expression is obtained:
