Abstract :
In this paper we compare the energy dependences (1-500 MeV) of the proton damage coefficients for p/sup +/n GaAs solar cells with previously reported calculations of nonionizing energy loss (NIEL). For proton energies E<10 MeV, the damage coefficients all follow an approximate 1/E dependence. For E>10 MeV, the damage coefficients vary but are bounded by the total and elastic NIEL.
