  8. The calculated results show that, for low energy protons ( energy less than several decade mev ), the contribution of proton nuclear reaction to energy deposition can be neglected ; while for high energy protons ( energy greater than several hundred mev ), the great difference appears for the above two cases. this gives us an indication that the contribution of proton nuclear reaction to the energy deposition must be concerned for high - energy protons. the propagation process in material of thermal shock wave induced by high - energy intense - current pulsed proton beam irradiation is calculated for several different proton energies
