Measuring the Low-Energy Cosmic Ray Spectrum with the AFIS Detector — •Martin Losekamm1,2, Dominic Gaisbauer1, Daniel Greenwald1, Alexander Hahn1, Philipp Hauptmann1, Igor Konorov1, Lingxin Meng1, Stephan Paul1, Thomas Pöschl1, and Dieter Renker31Physics Department E18, Technische Universität München — 2Institute of Astronautics, Technische Universität München — 3Physics Department E17, Technische Universität München

High-energy cosmic rays interact with Earth’s upper atmosphere and produce antiprotons, which can be trapped in Earth’s magnetic field. The Antiproton Flux in Space (AFIS) Mission will measure the flux of trapped antiprotons with energies less than 100 MeV aboard the nanosatellite MOVE 2. An active-target tracking detector comprised of scintillating plastic fibers and silicon photomultipliers is already under construction at the Technische Universität München. As a precursor to the space-bound mission, a prototype version of the detector will be launched aboard a balloon from Kiruna, Sweden as part of the REXUS/BEXUS student program by the German Aerospace Center (DLR). Named AFIS-P, it will be used to measure the low-energy part of the cosmic-ray spectrum for energies less than 100 MeV-per-nucleon. Spectrometers in previous balloon missions were not sensitive in this low-energy region. Thus AFIS-P will deliver unprecedented data, while simultaneously allowing us to field-test the AFIS detector.

This project is supported by DLR and the Cluster of Excellence “Origin and Structure of the Universe”.
