P̄ANDA Disc DIRC simulation and reconstruction

The P̅ANDA Disc DIRC is a novel detector concept for particle identification based on Detection of Internally-Reflected Cherenkov light (DIRC). A thin disc of ~1 m radius will be used as radiator and for light transportation. At the rim, crystal bars are foreseen to perform passive chromatic correction. Focussing light guides map the angles of the propagating photons to spatial positions on the focal plane of photon detection devices. For the required performance of the parallel-to-point optic the angular-position phase space of the propagating photons were investigated. Furthermore the hit pattern and time of arrival on the focal plane of a photon detection device for the generated photons were studied. The photon detector response information were used to reconstruct the particle properties.
