- ПубликацияТолько метаданныеNumerical Simulation of Radiation Anisotropy of the Pyroelectric Neutron Generator(2019) Gromov, M. B.; Kubankin, A. S.; Ionidi, V. Y.; Kaplii, A. A.; Kirsanov, M. A.; Кирсанов, Михаил АлексеевичThe pyroelectric neutron generator is a compact source of fast neutrons with an energy of 2.45 MeV and a yield up to approximate to 10(4) neutrons/s. The device is designed for calibration of low-background neutrino and dark matter detectors and may also serve as an alternative to traditional radioactive sources of fast neutrons in physical research and practical work. Numerical simulation of the angular distribution of neutrons emitted by the pyroelectric generator with the D(d, n)He-3 reaction proceeding within it was performed in order to calculate the neutron yield in the full solid angle and in a given direction correctly. The angular distribution was found to be anisotropic: the neutron yield increased in the direction of motion of incident deuterium ions. This anisotropy was as large as approximate to 25% at a maximum energy of 28 keV of incident particles. The anisotropy increased nonlinearly with the ion energy: it reached approximate to 70% at 50 keV and a monoenergetic flux, but was virtually zero below 10 keV. The obtained angular distribution is similar to that of neutrons in the case of a 15-keV monoenergetic flux of deuterium ions.

A.; Popovich, A. F.; Rusetskii, A. S.; Kirsanov, M. A.; Кирсанов, Михаил Алексеевич© 2022, Allerton Press, Inc.Abstract: The experimental data on the yield of d + d-reaction products for polycrystalline diamond target, obtained in the studies at the HELIS ion accelerator are presented. The equipment and neutron and charged particle detectors used in the study are described. The possibility of using the Unique Scientific Facility (USF) HELIS to verify operating characteristics of semiconductor detectors of alpha particles intended in studies of the boron–proton capture reaction at the Prometheus proton therapy complex is shown.
- ПубликацияТолько метаданныеInvestigation of Neutron Generation upon Irradiation of Deuterated Crystalline Structures with an Electron Beam(2021) Dalkarov, O. D.; Negodaev, M. A.; Rusetskii, A. S.; Kubankin, A. S.; Kirsanov, M. A.; Кирсанов, Михаил Алексеевич© 2021, Pleiades Publishing, Ltd.Abstract: The possibility of neutron generation by irradiating deuterated crystalline structures with an electron beam with an energy of 20–40 keV was studied. As targets, the deuterated crystalline structures of palladium and textured CVD diamond were used. Measurements of neutron emission are presented, which were carried out by three independent methods—scintillation detectors, counters based on He-3, and track detectors CR-39.The average neutron flux during irradiation was estimated as 1–10s-1 in 4π sr.

- ПубликацияТолько метаданныеInvestigation of the interaction of the ion beams with deuterated crystal structures at the HELIS facility(2020) Dalkarov, O. D.; Negodaev, M. A.; Rusetskii, A. S.; Oginov, A. V.; Kirsanov, M. A.; Кирсанов, Михаил АлексеевичThe paper reviews results obtained in the course of low energy nuclear reactions experimental study using the HELIS facility (LPI). The analysis of DD-reaction yields in deuterated crystalline structures at deuteron energies of 10-25 keV has shown a significant amplification effect. It was found that the exposure of deuterated targets both to 10-25 keV H+ and Ne+ ion beams and 20-30 keV X-ray radiation beams results in stimulation of DD-reaction yield. For CVD diamond and PdD x targets, it was shown that the magnitude of the neutron yield is affected by the orientation of the sample with respect to the deuteron beam. The possible explanation of the said effect may be attributed to the channeling of deuterium ions and neutron (DD reaction products) in textured targets. It was found that the heat release is much higher when D+ ion beams act upon the TiD x target than in case with H+ and Ne+ beams. The heat release depends upon the deuterium concentration in the target and the deuteron beam current density. "Additional peaks" were observed in the X-ray fluorescence spectra, but those are not related to any element and are seemingly associated with diffraction processes in deuterated palladium and CVD diamond.
- ПубликацияТолько метаданныеPassage of Fast Neutrons Through the Crystal Structure of Textured CVD Diamond(2020) Dalkarov, O. D.; Glushkov, N. A.; Negodaev, M. A.; Rusetsky, A. S.; Kirsanov, M. A.; Кирсанов, Михаил Алексеевич© 2020, Pleiades Publishing, Ltd.Abstract: The passage of fast neutrons through the crystal structure of a textured diamond obtained by chemical vapor deposition (CVD diamond) is studied. Neutrons with an energy of 2.45 MeV from the DD reaction and with an average energy of about 2 MeV from the 252Cf isotope are used as neutron sources. The neutrons are detected by two independent methods: using proportional counters filled with 3Не and a paraterphenyl-based scintillation detector. The measurements show that the neutron-flux incident on the detector depends on the orientation of the target. In the case of isotropic samples containing diamond and carbon, such effects are not observed. A possible explanation for the effect is the channeling of deuterium ions and neutrons in channels of textured CVD diamond.
