Abstract
The harsh space radiation environment affects both satellite equipment and astronauts. Although a lot of research on this environment has been performed, knowledge gaps remain. One of the main issues is the lack of data with a large spatial and temporal coverage. This can be resolved by the development of simple, compact, cheap but yet precise radiation monitoring tools. One such recently developed tool is a sensor chip based on floating gate dosimeters. In this thesis research, the interface between this chip and a CubeSat testbed has been tested. Additionally, proton beam tests have been performed to verify the characteristics of the sensor chip. It was concluded that the simple chip can be widely deployed, but that more testing is required to compare its performance with other dosimeter technologies.
