Under the contract between European Space Agency (ESA) and
the Paul Scherrer Institute (PSI) the Proton Irradiation Facility (PIF)
was constructed for testing of spacecraft components.
The facility is designed in a user friendly manner and is commonly
available. It enables generating of realistic proton spectra encountered
at any potential orbit in space. PIF is a member of the ESA supported
European Component Irradiation Facilities (ECIF).
