The Possibility of Using C3-C4 Calorimeter Leak Detectors for Neutron Registration in the GAMMA-400 Complex
(2020) Kadilin, V. V.; Naumov, P. Y.; Наумов, Петр Юрьевич
© 2020, Pleiades Publishing, Ltd.Abstract: The article describes the method for modifying the scintillation calorimeter detectors C3 (S3) and C4 (S4) of the GAMMA-400 space complex in order to obtain the possibility of detecting neutrons produced in the process of passing electrons (positrons) and high-energy protons through detector matter. The presented method will allow to increase the rejection factor of background radiation without degrading the basic capabilities of the detectors S3 and S4.

The Future Space-Based GAMMA-400 Gamma-Ray Telescope for Studying Gamma and Cosmic Rays
(2019) Topchiev, N. P.; Bakaldin, A. V.; Gusakov, Y. V.; Dalkarov, O. D.; Galper, A. M.; Arkhangelskaja, I. V.; Arkhangelskiy, A. I.; Leonov, A. A.; Naumov, P. Y.; Runtso, M. F.; Kheymits, M.

© 2019, Allerton Press, Inc.Abstract: The future space-based γ-ray telescope GAMMA-400 will be installed on the Navigator platform of the Russian astrophysical observatory. A highly elliptical orbit will allow prolonged (~100 days) continuous observations of many regions of the celestial sphere for 7–10 years. GAMMA-400 will measure fluxes of γ‑ray emission in the energy range of ~20 MeV to several TeV and electrons + positrons to ~20 TeV. The γ-ray telescope will have excellent separation of γ-ray emissions against the background of cosmic rays and electrons + positrons from protons, along with unprecedented angular (~0.01° at Eγ = 100 GeV) and energy (~1% at Eγ = 100 GeV) resolutions 5–10 times better than for the Fermi-LAT and ground-based γ-ray telescopes. GAMMA-400 observations will provide fundamentally new data on discrete sources and spectra of γ-ray emissions and electrons + positrons.

Forward Hodoscopes of Charged Nuclei Fragments for the BM @ N Experiment
(2021) Baranov, A. G.; Baskov, V. A.; Gerasimov, D. P.; Guber, F. F.; Naumov, P. Y.; Salakhutdinov, G. K.; Наумов, Петр Юрьевич; Салахутдинов, Гаяр Харисович
© 2021, Pleiades Publishing, Ltd.Abstract: Two versions of a forward hodoscope have been developed and manufactured based on scintillation and radiation-resistant quartz plates. The hodoscopes are designed to register ions in the BM @ N experiment at the NICA accelerator complex. The light outputs and their inhomogeneity were measured as a function of the coordinates of the passage of particles through the hodoscope plates on the calibration beam of the secondary electrons of the “Pakhra” synchrotron of the Lebedev Physical Institute.

Scintillation Crystals Based on Complex Oxides of Group 3 Elements

© 2020, Pleiades Publishing, Ltd.Abstract: Scintillation properties of crystals based on complex oxides of group 3 elements such as Y3Al5O12:Ce, Y3Al5O12:Sc, Y3Al5O12:Re, Y3Al5O12:Sc:La, YAlO3:Ce, YAlO3:Ce:Yb, YAlO3:Ce:Sc, YAlO3:Eu, YAlO3:Re, YAlO3:Ti, and YAlO3:Ce:Ti are studied. Crystals based on complex oxides of group 3 elements have high thermal shock resistance and high corrosive resistance. These crystals have good temporal characteristics with their relatively high density and energy conversion efficiency. It is shown that these scintillators can be promising for the design of α-particle spectrometers with good energy resolution.

The Amplitude Parameters of Prototypes of the Forward Hodoscopes for the BM@N Experiment
(2021) Baranov, A. G.; Guber, F. F.; Ivashkin, A. P.; Izvestnyy, A. V.; Salakhutdinov, G. K.; Naumov, P. Y.; Салахутдинов, Гаяр Харисович; Наумов, Петр Юрьевич
© 2021, Pleiades Publishing, Ltd.Designs of hodoscopes of nuclear fragments based on quartz and scintillation plates with light pickup by silicon avalanche photodiodes are described. Hodoscopes are planned for use in the BM@N experiment for registration of heavy nuclear fragments near the axis of the heavy ion beam. The results of measurements of light yields in detector elements based on quartz and scintillation plates on the electron beam of the synchrotron "Pakhra" (LPI) are presented. The measured nonuniformity of the light collection shows that readout from both sides of hodoscope detector elements is needed.
