Effects to be Considered
Low Energy protons ? mirror scattering
High Energy protons ? all directions ? Geant4 model of DERA
Dose accumulated over mission
NIEL (CCD degradation) dose or equivalent 10 MeV p+ fluence
Solar Cell 1 MeV e- Equiv. Fluences
These require the conversion algorithm from XMM RM detector counts ? FLUX (recently received)
