This study investigates the relationship between sensitivity and temperature during irradiation in MOSFET dosimeters. Three samples of commercial lateral p-channel 3N163 were exposed to Cobalt-60 radiation at temperatures ranging from 8 75 °C. Results indicate that no thermal dependence was observed up a dose Gy.
Thermal effects are especially relevant in PIN photodiode dosimeters which dark current depends exponentially on temperature. To minimize this effect, a thermal compensation procedure is presented relying the diode structure itself, without requiring any external sensor or device. Under irradiation, periodically switched from reverse to forward polarization for device temperature estimation. This estimation based linear relationship between voltage and when biased at constant current. has...
