Development of a method for the calibration of the backward end cap of the PANDA calorimiter — •Samet Katilmis¹, Alaa Dbeyssi¹, Alexander Greiner¹, David Rodriguez Pineiro¹, Dong Liu¹, Frank Maas^1,2,3, Julian Moik¹, Luigi Capozza¹, Oliver Noll^1,2, Peter-Bernd Otte¹, Sahra Wolff¹, and Cristoph Rosner¹ for the PANDA collaboration — ¹Helmoltz Institut Mainz, Germany — ²Institute of Nuclear Physics, Johannes Gutenberg University, Mainz, Germany — ³PRISMA Cluster of Excellence, Mainz, Germany

The PANDA-Experiment (Antiproton and Proton Annihilation at Darmstadt) is one of the main experimental pillars at the Facility for Antiproton and Ion Research at Darmstadt (FAIR), which currently is under construction.

The Backward Endcap Calorimiter (BWEC) is developed and built by the EMP group at the Helmholtz Institute Mainz. The BWEC consists of subunits called submodules. Each submodule houses electronic components, such as high voltage boards, ASICS, photodiodes, and others, whose characteristics must be determined for optimal operating settings. This includes determining the characteristics of avalanche photodiodes, high-voltage scans, and various other tests. This procedure is repeated several times for 48 submodules, so convenient, automatic and reconstructable calibration methods are developed.
