Event rates were calculated for LEO (ISS) and GEO environments by combining CREME96 orbital integral flux estimations and simplified SEE cross-sections according to methods shown in Heavy Ion Orbital Environment Single-Event Effects Estimations. Assume a minimum shielding configuration of 100mils (2.54mm) of aluminum, and worst-week solar activity (this is similar to a 99% upper bound for the environment). Using the 95% upper-bounds for the SEL and the SEB/SEGR, the event rate calculation for the SEL and the SEB/SEGR is shown on Table 9-1 and Table 9-2, respectively. Note that this number is for reference since no SEL or SEB/SEGR events were observed. SET orbit rate for the TPS7H60X5-SEP device is listed in SEB/SEGR Event Rate Calculations for Worst-Week LEO and GEO Orbits. As no SET events were observed, the numbers provided are for reference.
