Calibration of Detector Modules for the PANDA FAIR Phase-0 Calorimeter — Nicolo Baldicchi¹, Luigi Capozza¹, •Samet Katilmis¹, Dong Liu¹, Frank Maas^1,2,3, Julian Moik¹, Oliver Noll^1,2, David Rodriguez Piñeiro¹, Paul Schöner¹, Christoph Rosner¹, and Sahra Wolff¹ — ¹Helmholtz-Institut Mainz, Mainz, Germany — ²Institute of Nuclear Physics, Mainz, Germany — ³PRISMA+ Cluster of Excellence, Mainz, Germany

The PANDA FAIR Phase-0 Calorimiter consists of 48 submodules. Each submodule houses detector components, such as high voltage distribution boards, charge sensitive preamplifiers, avalanche photo diodes (APDs) and temperature sensors. The characteristics of these components must be determined to run the calorimeter in an optimal operating mode. Following parameters were determined and optimised. The APD gain as a function of the bias voltage at -25 ^∘C, the entrance area of the PANDA charge sensitive preamplifier and the characteristic curves of both the HV boards and the platinum temperature sensors. Furthermore a first energy calibration of the submodules by utilising atmospheric muons was performed. The talk points out both technical developments and results.
