Abstract

This viewgraph presentation discusses: radiation fundamentals, radiation damage, how radiation dosage is determined, fluence testing approaches, ionization damage exposure, displacement damage exposure, Europa energy "bins", rationale for group flux (energy bins), electron/proton group fluences, electron beam exposure testing, proton sources, reactor exposures, gamma exposures, preliminary exposure findings, testing caveats, preliminary conclusions, internal discharge, and electron dose depth curves.
