A Appendix: Total Ionizing Dose From SEE Experiments

The production TPS7H4003-SEP POL is rated to a total ionizing dose (TID) of 20 krad(Si). In the course of the SEE testing, the heavy-ion exposures delivered ≈10 krad(Si) per 107 ions/cm2 run. The cumulative TID exposure over all runs was determined to be between 3 krad(Si) to 20 krad(Si) for each device. All four production TPS7H4003-SEP devices used in the studies described in this report stayed within specification and were fully-functional after the heavy-ion SEE testing was completed.
