We present results and analysis investigating the effects of radiation on a variety of candidate spacecraft electronics to heavy ion and proton induced single event effects (SEE), proton-induced displacement damage dose (DDD), and total ionizing dose (TID).
With challenges related to testing highly complex integrated circuits as well as entire systems continuing to grow, the use of higher energy heavy ions for single-event effects (SEE) testing becomes a critical technical need. This presentation, however, focuses only partially on the technical side with the main emphasis on the economics of using a high-energy heavy ion beam and comparing via notional cost models for testing.
Total ionizing dose, displacement damage dose, and single event effects testing were performed to characterize and determine the suitability of candidate electronics for NASA space utilization. Devices tested include FETs, flash memory, FPGAs, optoelectronics, digital, analog, and bipolar devices.
This presentation will document the current state of high energy (>200 MeV) proton access in the U.S. for Single Event Effects (SEE) testing. This is continuation of efforts since the shutdown of the Indiana University Cyclotron Facility (IUCF).

Total ionizing dose irradiations were performed on a 22 nm fully-depleted silicon-on-insulator static random access memory. There is a strong well-bias effect in the TID response. Combined TID and SEE results are also presented.
