SEE in-flight measurement on the MIR orbital station

SEE spaceflight measurements are presented on HM65756 SRAM from Matra-MHS, Seeq 28C256 and Motorola MC68020 microprocessor (bulk version) in the MIR station orbit (350 km altitude, 51.6/spl deg/ inclination). Accelerator testing (heavy ion and proton) of flight spares permits the prediction of the event rates using standard model such as CREME and SPACERAD/sup 1/ as well as characterisations of the flight components allowing the comparison of in-orbit observations. Event rate prediction and ground-testing data are compared. >
