Large-area-diode based micro-dosimeter concept for a femto- satellite — Roman Bergert, •Nico Krug, Hans-Georg Zaunick, and Kai-Thomas Brinkmann — II. Physics Institute Justus-Liebig- University Giessen

A low-budget micro-dosimeter concept based on a large area diode (5×5 mm² sensitive area) and commercial of-the-shelf (COTS) components is designed and integrated to operate on an open-community femto-satellite platform provided by AmbaSat Ltd. The satellite platform is limited to a dimension of (3.5×3.5 cm²) with a space of about 2×2 cm² for the dosimeter concept. Besides this challenge of space for the integration of the electronics on the platform, the challenge to operate in free harsh-space environment (radiation, vacuum, temperature) has to be overcome in the concept design. To target these challenges, several stress tests were performed, which will be presented with a performance mapping of the different components for their physical and electrical properties together with a discussion of the device performance.
