- ПубликацияТолько метаданныеMethods for obtaining linear energy distribution in a small volume from nuclear fragmentation events caused by space radiation(2021) Fedotov, S. N.; Kushin, V. V.; Федотов, Сергей Николаевич; Кушин, Владимир Васильевич© 2021The microdosimetric approach to the interpretation of nuclear fragmentation events generated by cosmic radiation in near-earth orbits is described. A method is proposed for calculating the linear energy in the interactions of secondary charged fragments with a sensitive volume. All calculations were carried out using dE/dx values obtained in data processing of space experiments. The probability density distributions of linear energy in micro volumes of water for different types of fragmentation events are obtained.

- ПубликацияТолько метаданныеDescription of nuclear fragmentation events induced by space radiation: An analytical approach(2022) Fedotov, S. N.; Kushin, V. V.; Федотов, Сергей Николаевич; Кушин, Владимир Васильевич© 2022 Elsevier B.V.One of the features of the field of space radiation inside a spacecraft during an orbital flight is the presence of a secondary component in its composition. This component is generated in the environment due to nuclear interactions of primary radiation with the walls of the spacecraft, material load, biological objects, electronics, etc. Secondary radiation consists mainly of charged particles of a wide energy range and neutrons. The fluence of secondaries can be non-uniform, especially in the region adjacent to the vertex of the nuclear interaction. In this region, the local energy absorbed in matter can significantly exceed the volume average values. In this paper a calculation method is considered and the probability of large energy transfer in fragmentation events in the vicinity of the nuclear interaction vertex is estimated.
