Description

Precise measurements of the muon content of extensive air showers are essential for the identification of the chemical composition of ultra-high-energy cosmic rays. We therefore propose a new scintillator detector prototype, the Aachen Muon Detector (AMD). It can complement existing ground arrays composed of e.g. water Cherenkov detector stations. The detector consists of 64 scintillator tiles read out by silicon photomultipliers (SiPM) which are located in a steel housing which could be placed beneath the existing detector stations. SiPMs promise a photon detection efficiency which outperforms current photomultiplier tubes. In combination with their compact package, low cost per light sensor and a moderate bias voltage ($<100$ volts) a modular and robust design can be achieved. We present the current status of the AMD prototype, including first characterization measurements of the scintillator tiles and first promising simulation studies. We use a detailed detector simulation based on Geant4 to determine the efficiency of the AMD detector to reconstruct the simulated muon number in air showers.
