Several samples irradiated simultaneously if possible.Devices unbiased, grounded, facing beam.
Exposures -Two campaigns performed.Energy: 6 and 30 MeVFluency: from 107 to 1012 p/cm2
Fluxes: from 106 up to 5·108 p/cm2
Analysis -Performed by ESA-ESTEC

PROTONIRRADIATIONFACILITYCalibration of SREM Batch ( CSAG - ESA - PSI )
Standard Radiation Environment MonitorSREM – developed in partnership: ESA, PSI and Contraves Space AG.Monitors for PROBA and ROSETTA satellites manufacturedby Contraves AG, calibrated by PSI and delivered to ESA.
SetupExample see Photo
Procedure -I Short Functional Test, 60Co and Cosmic Ray checkII Low energy response at 0°II-a Thresholds determinationIII Detector area measurementIV Dead-time determinationV Full response calibration/set of energies and angles
Analysis -Simulations done for exactly the same energies as in experiment.Angular positions changed for the whole set of proton incidence angles.
Conclusions -Two tested SREMs meet their specifications.Agreement experiment-simulations in general very good.
