Abstract

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.

宇宙射线原子核的碎裂及其实验研究
本文讨论了核碎裂过程对描述宇宙射线传播的重要性,以及对解决提高航天器机载电子设备抗辐射能力的实际重要问题的重要性。目前缺乏质子与原子核低能相互作用的实验数据。对于破碎过程的实验研究,提出用重离子束进行实验。在研究航天器电子元件基底抗辐射能力的同时,提出测量宇宙射线质子与航天器材料和电子元件基底相互作用产生二次同位素的有效截面。
