Development of a radiation monitoring system for satellite application — •Fabian Abo, Marius Hötting, Kevin Kröninger, and Jens Weingarten — Technische Universität Dortmund, Lehrstuhl für Experimentelle Physik IV

The use of commercial electronics components in satellites is increasing. Therefore, the understanding and investigation of radiation induced damages are inevitable. The Lehrstuhl für Experimentelle Physik IV at Technische Universität Dortmund is developing a radiation monitoring system based on Commercial-of-the-shelf (COTS) semiconductor components. The main principle is to detect and monitor the radiation induced damages. Nevertheless, the device is able to detect multiple particle types, store information about the accumulated dose and detect Single Event Effects (SEE) which could lead to a Bitflip as well as severe failure of electronical devices on board.
However, the radiation monitoring device has to operate within a defined bandwidth and a limited power usage to be useful as an additional payload.
In this talk we will present the results of temperature and radiation induced changes of different MOSFETS and diodes characteristics.
