Varadis RADFETs provide critical data on Rosetta Space Mission
Abstract: On its more than 10 years journey to comet 67P/Churyumov–Gerasimenko, Rosetta carried RadFET ionising dose monitors in the central electronics of the orbiter instrument COSIMA and the lander instrument SESAME. The readings of the dosimeters were corrected for the temperature of the devices during measurements. Because the sensitivity of…

Gamma-Ray Irradiation and Post-Irradiation Responses of High Dose Range RADFETs
Abstract: Gamma-ray irradiation and post-irradiation responses have been studied for the two types of radiation sensitive p-channel MOSFETs (RADFETs) from different manufacturers. In addition to, in dosimetric applications standard, threshold voltage measurements at a single specified current, transistor – and charge-pumping characteristics have been monitored. This has been shown to…
