Comparative measurements of single event upset and total dose environments using the CREAM instruments

The Cosmic Radiation Environment and Activation Monitor (CREAM) is taking regular measurements in the upper atmosphere on board Concorde, while a different version of the same instrument is scheduled for flights on the Space Shuttle in September and November 1991. Meanwhile, a sister instrument (CREDO) is continuously monitoring the environment in Sun-synchronous orbit on board UOSAT-3. These simultaneous flights of similar instruments enable intercomparison of environments as well as verification of predictive models and correlation with device behavior. The extensive data set encompasses both quiet-time data and solar-particle events. Both Concorde and UOSAT-3 results are examined.<
