Abstract :
The energy-deposition spectra measured by the CRRES (Combined Release and Radiation Effects Satellite) pulse height analyzer (PHA) experiment are reexamined to determine the relative contributions from the different mechanisms by which large localized energy-deposition events can be generated in silicon detector volumes flown in space. Comparisons with calculations generated by the CUPID simulation model modified to include pion-production and elastic-scattering events are used to generate a "best fit" trapped proton spectrum that is compared to the predictions of the NASA models for the CRRES orbit.
