A teststation for submodules of the forward endcap of the PANDA electromagnetic calorimeter — •Merlin Rossbach, Matthias Kube, Ulrike Thoma, Christoph Schmidt, and Christoph Wendel for the PANDA collaboration — Helmholtz-Institut für Strahlen- und Kernphysik, Universität Bonn, Germany

The forward endcap of the electromagnetic calorimeter of the PANDA experiment is currently being constructed. Its crystals are grouped into submodules consisting of 16 or 8 crystals each. Before these modules are mounted in the detector careful testing is needed and a pre-calibration will be performed at -25^∘C, the defined working temperature of the detector. A teststation has been developed using cosmic particles transversing the PbW0₄-crystals. Cosmic events are selected by two compact trigger detectors. Each of them contains a 4x4 array of scintillators, which are read out by silicon photomultipliers (SiPMs). The poster presents the setup of the teststation discussing in detail the different electronic components used.
