Time-based simulation of the PANDA EMC — •Jifeng Hu, Martin Johannes Galuska, Wolfgang Kühn, Jens Sören Lange, Yutie Liang, and Björn Spruck — II.Physikalisches Institut, JUSTUS-LIEBIG University Giessen, 35392, Germany

The PANDA detector is a general-purpose detector for antiproton physics that will be operating at FAIR. The detector will be running at interaction rates of up to 30 MHz, leading to significant pile-up of events. As an important component of the detector, the electromagnetic calorimeter (EMC) will be exposed to this high rate environment. To understand the implications such as potential loss of efficiency or resolution, a framework for time-based simulation has been implemented within the PandaRoot software package. In this presentation, the concept of this simulation will be explained and the photon detection efficiency as a function of energy, polar angle, and event rate will be discussed.
