Development of Radiation Detector (Radiation Module) With Three Different Sensors for Space Applications

Abstract

The novel domestic radiation sensors -called "NürFETs" -can be used to measure Total Ionizing Dose (TID) on the mission orbit. NürFET responses are compared with two different sensors on the market with demonstrated performance. The radiation detector reader has been designed by the Space Technologies Research Institute (TUBITAK UZAY) and named MURaD and it contains three distinctive sensors, namely the aforementioned Nuclear Radiation Sensing Field Effect Transistor (NürFET), the p-channel RADFET, and the Floating Gate Dosimeter (FGDOS), respectively. They are used to measure TID comparatively and separately. The whole radiation module contains three different sensors which are exposed to gamma radiation on the ground via a Co-60 source and the functional and/or parametric test results are presented.
