PRODUCTION DATA
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 Heavy Ion Orbital Environment Single-Event Effects Estimations. A minimum shielding configuration of 100 mils (2.54 mm) of aluminum and worst-week solar activity is assumed. (This is similar to a 99% upper bound for the environment.) Note that this number is for reference since no events were observed.
| Orbit Type | Onset LETEFF (MeV-cm2 / mg) | CREME96 Integral FLUX ( / day / cm2) | σSAT (cm2) | Event Rate (/ day) | Event Rate (FIT) | MTBF (Years) |
|---|---|---|---|---|---|---|
| LEO (ISS) | 43 | 6.40 × 10–4 | 1.23 × 10–7 | 7.87 × 10–11 | 3.28 × 10–3 | 3.48 × 107 |
| GEO | 2.17 × 10–3 | 2.67 × 10–10 | 1.11 × 10–2 | 1.03 × 107 |
