Validation studies of Lightyield non-linearity implementation within the PandaRoot simulation framework — Kai-Thomas Brinkmann, •Simon Glennemeier-Marke, and Markus Moritz for the PANDA collaboration — Justus-Liebig-University Giessen

The PANDA detector at FAIR/GSI Darmstadt will utilize an electromagnetic calorimeter to measure the energies of photons being generated in proton-antiproton collisions. The calorimeter will use tapered PWO-II crystals and will cover a significant fraction of the 4π solid angle. These crystals show a strong tapering along their length. Due to this asymmetric geometry and absorption phenomena, the light yield varies non-uniformly along the long axis of the crystals. This project utilizes simulations within the PandaRoot simulation framework to validate the computational implementation of the non-uniformity and compare it to experimental results of previous studies. This project was supported by BMBF, GSI and HFHF.
