Radiation in space consists of charged particles, photons, and neutrons. We aim to measure the charged nuclear component of the radiation environment with CubeSat-sized detectors composed of scintillating-plastic fibers read out by silicon photomultipliers (SiPMs). With different detector versions, we study the radiation’s composition for dosimetry with the RadMap Telescope and aim to measure the flux of antiprotons trapped in the Earth’s magnetic field with the upcoming AFIS mission.
For the latter, we are currently improving the detector design and plan to verify the updated version as part of the In-Orbit Verification Experiment 1 (IOV-1) on the International Space Station.
In this talk, I will present the current detector design as used in the RadMap Telescope, as well as the opportunities for improvement we identified during production and calibration. Furthermore, I will show which changes we plan to apply to the current design to achieve a better performance and simplify production for future missions.
Our work is funded by the German Research Foundation (DFG, project number 414049180) and under Germany’s Excellence Strategy - EXC2094 - 390783311.
