“…More powerful simulation codes should be used with a wide list of modeled processes, including the formation and tracking of recoil nuclei and nuclear reaction fragments. We have developed an analytical approach to calculate the cross sections that depend on the mass, charge, departure angle, and kinetic energy of nuclear reaction products [41,42]. The approach is based on the use of current models concentrated in the EMPIRE II 19 program pack age [43].…”

The radiation environment in space is reviewed in short as an impact factor affecting onboard spacecraft electronics. The mass and energy distributions of the heavy component of space radiation and the contribution of galactic cosmic rays to the general flux are analyzed during a quiet period in solar activity. The nature of the limitations in the concept of linear energy transfer, including the effects of electronic semicon ductor component crystallinity, is discussed. Protective measures against upsets in onboard electronics, caused by cosmic ray ions, are considered.

“…Special features of silicon fragmentation induced by high-energy cosmicray protons were explored in previous studies of our group [3][4][5][6]. In [5], it was shown that the results of the calculations performed on the basis of the reaction model according to the EMPIRE code are sensitive to the choice of values for the parameters of the optical-model potential.…”

“…In [5], it was shown that the results of the calculations performed on the basis of the reaction model according to the EMPIRE code are sensitive to the choice of values for the parameters of the optical-model potential. In the present article, the results obtained by calculating for the 28 Si + p, 27 Al + p and 183 W + p nuclear reactions, the cross-sections for elastic and inelastic scattering and the charge, mass, and energy distributions of heavy reaction products according to the TALYS [7] codes are supplemented with the results of the calculations for the same features of the 63 Cu + p reaction.…”

In continuation and development of our previous works where nuclear reactions of moderate energy (10 -400 MeV) protons with Si, Al and W have been investigated, the results of reactions with Cu are reported in this paper. Cu is a most important component in composition of materials in contact pads and pathways of modern and perspective ultra large-scale integration circuitry, especially in 3D topology.It is impossible to imagine a modern spacecraft without electronic integrated schemes with connecting and contact paths and areas, inter-layer conducting connections, and other metallic components. Such interior components normally have a high concentration of Al, Fe, Ni, Cu, Mo, Ta, W, Pt, Au, and other chemical elements.The kinematical effect of the energy transfer in a head-on collision from incident proton to a target nucleus is weaker for heavier target nucleus, but the resulting recoil energy can be sufficient to cause a dangerous upset of the electronics in the case of a high energy of incident proton. For example, 1 GeV proton encountering a head-on collision with a gold nucleus loses only about 2% of its energy but transfers an energy of about 20 MeV to the target gold nucleus. Head-on collisions are quite rare, elastic collisions occur predominantly at nonzero impact parameters, with the result that the kinetic energies of recoil nuclei form a spectrum associated with a specific angular distribution of recoil nuclei [1,2].
