“…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 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].
