Work towards a small scale detector array for cosmic showers based on scintillation detectors — •Erik Euler, Hans-Georg Zaunick, Kai-Thomas Brinkmann, Marvin Peter, Simon Glennemeier-Marke, and Mohammed Hassan — Justus Liebig University, Gießen, Germany

The detectors from the MuonPi Cosmic Detector Project are used to measure muons from cosmic air showers (secondary cosmic radiation). A MuonPi utilizes a plastic scintillation detector with a silicon photomultiplier (SiPM) for signal read out by RaspberryPi-based data acquisition. A larger, distributed detector array with 16 single detectors based on the MuonPi hardware, but with large plastic scintillator bars (100 x 100 x 10 cm), is currently under construction in Giessen. Its final goal, beside the mere detection of shower events, is to determine the direction of the shower through time-of-flight measurements and its special orientation in combination with the MuonPi Network.
Over the course of the last year a working prototype of the detector array was built and tested in the lab. The current setup consists of three working detector bars, the main part of the array’s central data acquisition with a prototype of the FPGA-based event analysis. The current status of the project as well as the next steps will be presented.
