D.3 Timing and tracking for the Crystal Barrel detector

R. Beck, R. Novotny

In order to enhance the trigger capabilities of the Crystal Barrel experiment, a new Avalanche-Photo-Diode readout, which will provide a good time resolution while maintaining the excellent energy resolution of the calorimeter, has been developed and will be installed in 2013. The future energy readout is planned to be realized with modern sampling ADCs to further enhance the rate capability. Additionally, a prototype Time-Projection-Chamber was developed, which can be integrated into the Crystal Barrel setup to provide tracking information for charged final state particles.
