Abstract

The Meteosat-3 radiation effects experiment includes two 256-kb SRAMs configured for SEU detection and a RADFET array for dose measurement. SEU rates and doses are enhanced during solar flares. Two years of orbital data are compared with ground tests and prediction. The measured background dose is found to be lower than prediction. The measured solar flare dose agrees well with prediction. The view angle of the RADFETs was insufficient to allow the relative efficiency of low-Z/high-Z shielding to be verified.
