Документ Increasing the resolving power of determining the point gamma-radiation source direction in the precision method(STC "Institute for Single Crystals", 2017) Grigoryev, A. N.; Bilyk, Z. V.; Litvinov, Yu. V.; Polyansky, N. E.; Sakun, A. V.; Marushchenko, V. V.; Cherniavskyi, I. Yu.; Voronkin, E. F.; Petrukhin, S. Yu.; Kasian, S. V.Experiments have demonstrated the possibility of increasing the resolving power of determining the point gamma-radiation source direction in the precision method. The work involved reducing the step of the angle of rotation of an asymmetric absorber and shifting the detector relative to the maximum-minimum absorber thickness boundary. The 137Cs gamma-radiation source direction was determined within the angles of the maximum and minimum thickness boundaries of the asymmetric absorber. The detector position was investigated for the maximum thickness of the asymmetric absorber on the boundary between the maximum and minimum thickness, and for the minimum thickness. The optimal position of the detector was found for the asymmetric absorber boundary, enabling to determine the maximum count rate in the gamma source direction. A specific position of the detector enables observing an increasing gamma radiation scattering over the copperlead surface. The experiment used absorbers with spectrometric telluride-cadmium detectors. Information from the detectors was output to four multichannel gamma-radiation impulse analysers, which operated simultaneously in the spectrometer mode.Документ Measuring the amplitude-time characteristics of a pulsed high-intensity gamma radiation acceleratorVarian Clinac 600C aCdTe detector(STC "Institute for Single Crystals", 2019) Grigoryev, A. N.; Bilyk, Z. V.; Litvinov, Yu. V.; Cherniavskiy, I. Yu.; Polyansky, N. E.; Snarenky, V. P.; Samofalov, I. A.; Voronkin, E. F.; Sosnutska, O. O.; Petrukhin, S. Yu.; Suchkov, G. M.; Bilyk, N. G.; Indykov, S. N.; Matykin, V. B.; Pysariev, S. A.; Matykin, O. V.; Menshov, S. N.Measurements of the amplitude-time characteristics of a high-intensity pulsed gamma radiation accelerator Varian Clinac 600C with photon energy from 1 to 6 MeV on the equipment using a CdTe detector in both current and pulse modes have been carried out. It is shown that the operation of the CdTe detector in the current mode allows one to control the frequency of the accelerator pulses, and the operation of the CdTe detector in the pulse mode allows for determining the dose in each pulse with an error of 0.06 %. Monitoring the operation of the accelerator Varian Clinac 600 C shows that the pulses come in batches; within the batch, the pulse repetition period corresponds to a specified frequency at the accelerator, while the repetition period of the batches differs from the specified frequency. Dose control in the pulses showed its 5 % excess over the average value during the first 2.5 s of the accelerator operation, whereas during the last 2 s, the dose reduction by 1.8 % was observed.Документ Physico-mathematical model for determining the direction in space to point sources of gamma radiation using spherical absorber(STC "Institute for Single Crystals", 2018) Grigoryev, A. N.; Bilyk, Z. V.; Pettersson, I.; Litvinov, Yu. V.; Polyansky, N. E.; Sakun, A. V.; Marushchenko, V. V.; Cherniavskyi, I. Yu.; Voronkin, E. F.; Sosnutska, O. O.; Petrukhin, S. Yu.; Indykov, S. N.; Haydabuka, V. E.Physico-mathematical model for determining the direction in space to point sources of gamma radiation using a spherical absorber was developed. CdTe detectors of appropriate sizes are placed in the regular pyramid tops under absorber. The physico-mathematical model allowed, taking into account the exponential attenuation of gamma radiation by the absorber, to find the distance from the location of any CdTe sensor to the surface of sphere in any direction in space. Calculated information and signal received from the detectors, correlate to each other. The ratios found depend on the angle to the source of gamma radiation and represent the ratio of transmittance coefficients for four sensors. A methodology for locating the developed device in space, which allowed to obtain dependence of the calculated ratios from the angle in space for θ = 90° and φ from 0 to 360° in increments of 15° was proposed. Each direction in space corresponds to a set of six respective ratios.
