NUCLEAR AND DAMAGE EFFECTS IN SI PRODUCED BY IRRADIATIONS WITH MEDIUM ENERGY PROTONS

Calculations have been performed to obtain the types of ions and their recoil energies that result from the irradiation of Si with intermediate energy (70-600 MeV) protons. A version of the High Energy Transport Code (HETC) was employed for this purpose. A first dosimetry measurement confirms the production of Na and Be as a result of the irradiation. The binary collision approximation, as used in the MARLOWE code, is then used to estimate the density of defect clusters in the resulting damaged structure.
