Space radiation monitoring with Timepix

Space radiation monitors have lately become increasingly interesting for space agencies and satellite developers. During the lifetime of the satellite, the dynamic development of the radiation environment caused by geomagnetic storms or solar eruptions can be studied. Continuous Earth magnetosphere monitoring allows us to obtain information on the composition, flux, spectrum, and direction of the arrival of energetic particles, including time and space fluctuations of these parameters. In addition to scientific research, these data provide very valuable information about the effects of dangerous cosmic rays on satellites and spacecraft crews. In this paper, we present an overview of Timepix-based radiation monitors currently in space and in future missions.
