Detector response simulations for the CBM-TRD — •Lena Rossel for the CBM collaboration — Institut für Kernphysik, Goethe Universität, Frankfurt am Main

To ensure the best functionality of the Transition Radiation Detector (TRD) of the Compressed Baryonic Matter (CBM) experiment at the future Facility for Antiproton and Ion Research (FAIR), it is crucial to simulate the detector response as precisely as possible. Simulations are an instrument to optimize the detector design and account for possible challenges in the extraction of physics observables affected by design decisions.

After the event generation, the propagation of the particles through the detector setup is simulated with GEANT3. The detector behavior, including signal generation and collection, is simulated. This includes handling of transition radiation photons, energy deposition in the detector gas and signal-digitization.

In this contribution the general process of the detector response simulation is carried out with CbmRoot for the CBM-TRD. The focus lies on the reconstruction of the specific energy loss for charged particles. In addition, DESY test beam data of one TRD module will be compared to the simulation results. This work is supported by the BMBF-grant 05P21RFFC3.
