Abstract :
The Standard Radiation Environment Monitor (SREM) was designed in a cooperation between ESA-ESTEC, PSI and Contraves Space-the manufacturer. The monitor detects cosmic particles using 3 direction sensitive Si detectors. Total dose measurement is performed with internal and external RADFETs located at selected positions on the satellite. Their sensitivity towards protons and gammas was characterised for various energies, dose rates and exposure geometry
