Abstract. The results of a destructive single-event effect susceptibility radiation test of the PNI RM3100 magnetometer sensor, specifically the MagI2C ASIC (application specific integrated circuit) on the sensor board are presented. The sensor is a low-resource commercial-of-the-shelf (COTS) magneto-inductive magnetometer. The device was monitored for destructive events and functional interruptions during exposure to a heavy ion beam at the Lawrence Berkeley National Laboratory’s 88” Cyclotron. The RM3100 did not experience any destructive single-event effects when irradiated to a total fluence of 1.4 x 107/cm2 at an effective linear energy transfer (LET) of 76.7 MeVcm2/mg while operated at nominal voltage (3.3 V) and elevated temperature (85 °C). When these results are combined with previous total ionizing dose tests showing no failures up to 150 kRad(SI), we conclude that the PNI RM3100 is extremely radiation tolerant and can be used in a variety of space environments.

Short summary
The commercial-off-the-shelf (COTS) PNI RM3100 Magnetometer was tested for single-event latchup (SEL) at Lawrence Berkeley National Laboratory's heavy-ion beam and did not experience any single-event effects at a linear energy transfer > 75 MeVcm2/mg. Coupled with previous total ionizing dose (TID) testing at the University of Michigan and NASA Goddard Space Flight Center that showed no degradation in performance upto 150 kRad(SI), the COTS PNI RM3100 is extremely radiation tolerant.
