Description
The electrostatic accelerator (ESA) EG-5 occupies its unique niche as part of the complex of nuclear physics facilities of the FLNP JINR (Dubna, Russian Federation). The beams of high-energy particles (H+, He+, D+) produced using EG-5 have high energy stability (± 15 keV per 2 MeV), which makes it possible to conduct unique studies of the elemental composition of solids (meteorites), including deep profiling, conducting studies of nuclear reactions on fast neutrons (4.1-4.5 MeV). The energy of the accelerated particles is in the energy range of cosmic rays (from 10^5eV) which makes it possible to study the effects of cosmic rays on the properties of the Earth and astrophysical objects.
The mechanisms of the effect of cosmic radiation on the evolution of living organisms of the Earth on the example of rice seeds are beginning in the group “EG-5 Installation” of the JINR [1]. A cross sections of the 25Mg(n,α)22Ne reaction it has been clarified compared with existing measurements (evaluations and talys-1.8 code calculations). According to the detailed balance principle, a new information about the 22Ne(α,n)25Mg reaction, which is one of the main neutron sources for the astrophysicals process was obtained [2]. The Al2O3 - ZrO2 - Y2O3 - ceramics, NbTi - alloys high-entropy alloys promising for the manufacture of thermonuclear reactor; unique studies of degradation of semiconductor heterojunctions of solar cells (SiO2/TiO2) under the action of cosmogenic radiation are conducted in JINR using the EG-5 accelerator.
