Timebased Detector Simulation for the PANDA Experiment — •Tobias Stockmanns — Institut für Kernphysik, Forschungszentrum Jülich GmbH

PANDA is one of the main experiments of the future Facility for Antiproton and Ion Research (FAIR) at Darmstadt. Its purpose is the examination of the strong force in the energy regime of charmonium spectroscopy. For this goal PANDA uses a phasespace cooled antiproton beam with a momentum range of 1.5 - 15 GeV/c which interacts with either a hydrogen target or with more complex nuclei.

To be able to handle different physics questions PANDA abstains from the use of a first level hardware trigger. The complete detector data is read out to the control room where a software based event selection is done with the full PANDA data set.This readout concept sets huge requirements on the readout system of PANDA as well as the used trigger algorithms. To be able to develop and test those it is necessary to do a chronologically ordered data simulation which differs strongly from the usual event based Monte-Carlo simulation of detectors.

The existing simulation software pandaRoot was extended to give both possibilities: event and time based simulation. The concept and first simulation results will be shown in the presentation.
