Development and Verification of a Compact TDC-Based Data Acquisition System for Space Applications — •Martin Losekamm^1,2, Dominic Gaisbauer¹, Igor Konorov¹, Stephan Paul¹, and Thomas Pöschl¹ — ¹Physics Department E18, Technische Universität München — ²Institute of Astronautics, Technische Universität München

The advances of solid-state detectors and in particular those for the detection of photons have made their application in space systems increasingly attractive in recent years. The use of, for example, silicon photomultipliers (SiPM) paired with a suitable scintillating material allows the development of compact and lightweight particle detectors. The Antiproton Flux in Space experiment (AFIS) intends to measure the flux of antiprotons trapped in Earth's magnetosphere aboard a nanosatellite using an active target tracking detector, consisting of plastic scintillating fibers read out by SiPMs. In order to implement a large number of detector channels while adhering to the given space, mass and power constraints, the development of a compact TDC-based data acquisition system was proposed. This talk will present a current prototype featuring 900 channels, real-time multi-channel temperature measurement and bias regulation. Possible alternative applications as well as the next steps in the development will also be discussed. This work is supported by the Excellence Cluster 'Origin and Structure of the Universe'.
