SREM is a particle detector developed for space applications. It measures high energy electrons and protons with a fair angular and spectral resolution and provides the host spacecraft with radiation information. SREMs have been launched on several satellites: Strv-1c, Proba-1, Integral, Rosetta, GIOVE-B, Herschel, Planck, and Rosetta. SREM is the successor of the Radiation Environment Monitor REM
Proton counts, measured by SREM (in different energy ranges) onboard the Integral spacecraft, are plotted for the last 5 days. Peaks during quiet conditions correspond to the phases when the spacecraft crosses the radiation belts. Integral moves on a 72h HEO around Earth. The plots are made by BIRA-IASB using the near real-time (level 1) Integral/SREM data retrieved from ODI.
