Fragmentation of Cosmic Ray Nuclei and Its Experimental Study

The article discusses the importance of nuclear fragmentation processes for describing the propagation of cosmic rays, as well as for solving practically important problems of increasing the radiation resistance of spacecraft on-board electronics. There is a lack of experimental data on low-energy interactions of protons and nuclei. For the experimental study of fragmentation processes, it is proposed to carry out an experiment with heavy ion beams. Alongside the study of the radiation resistance of the electronic component base of spacecraft, it is proposed to measure the effective cross sections for the production of secondary isotopes during the interaction of cosmic ray protons with spacecraft materials and the electronic component base.
