T1  - Alternative geometrical designs for quartz-based cherenkov detectors for the PANDA barrel DIRC detector
N2  - The PANDA experiment will be one of the flagship experiments at the future Facility for Antiproton and Ion Research (FAIR) in Darmstadt, Germany. It is a versatile detector dedicated to topics in hadron physics such as charmonium spectroscopy and nucleon structure. A DIRC counter will deliver hadronic particle identification in the barrel part of the PANDA target spectrometer and will cleanly separate kaons with momenta up to 3.5 GeV/c from a large pion background. An alternative DIRC design option, using wide Cherenkov radiator plates instead of narrow bars, would significantly reduce the cost of the system. Compact fused silica photon prisms have many advantages over the traditional stand-off boxes filled with liquid. This work describes the study of these design options, which are important advancements of the DIRC technology in terms of cost and performance. Several new reconstruction methods were developed and will be presented. Prototypes of the DIRC components have been built and tested in particle beam, and the new concepts and approaches were applied. An evaluation of the performance of the designs, feasibility studies with simulations, and a comparison of simulation and prototype tests will be presented.
