9 Event Rate Calculations

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 described in SLVK046. A minimum shielding configuration of 100 mils (2.54 mm) of aluminum, and worst-week solar activity (this is similar to a 99% upper bound for the environment) is assumed. Using the 95% upper-bounds for the SEL, SET, and the SEB and SEGR, is shown in Table 9-1and Table 9-2 show the event rate calculation for the SEL, SET, and the SEB/SEGR, respectively.

Table 9-1 SEL Event Rate Calculations for Worst-Week LEO and GEO Orbits The SEL Event Rate is for reference only as not a Single Unit during any Run showed a Latch-up event.
