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- Card 1/5 2'695 S/12o/6i')000/003/005/041 A Scintillation Spectrometer .... E032/E314 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 Card 2/5 27695 S/120/61/000/003/005/041 A Scintillation Spectrometer E032/9314 12 1 7-1' 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. Card 3/5 27695 s/lzo/61/000/003/005/041 A Scintillation Spectrometer ....

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).

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.

TITLE: Calculation of the spectrum of neutrons reflected from a protective barrier 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" Card 1/2 ACCESSION NR: AT4021262 increases.

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).

TITLE: Response delay time in proportional counters SOURCE: Voprosy* dozimetrii i zashchity* ot izlucheniy, no, 2, 1963, 185-190 TOPIC TAGS: proportional counter, response time, BF , neutron spectrum, SNM-5, a particles, scintillation counter, differential analyzer, jitter 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 Cord 1/2 ACCESSION VR: AT4021270 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 3 determines the proper resolution of spectrometers in transit time with boron counters and allows the corresponding processing of the spectra to be introduced.

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 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.
