The cumulative fraction of the displacement damage dose deposited in shielded GaAs solar cells in typical space proton environments is presented as a function of energy from the threshold for atomic displacement up to 400 MeV. Results are presented for silica cover glass thicknesses from 3-30 mils, and for both slowed down and incident proton energies. As an example, it is found that for cells shielded by 30 mils of coverglass in a circular 5000 km orbit, less than 15% of the degradation is caused by protons with slowed down energies <0.1 MeV, whereas 50% of the total degradation is produced by protons in the energy range 1
