The PANDA detector at the international accelerator Facility for Antiproton and Ion Research in Europe (FAIR) in Darmstadt (Germany) will address fundamental questions of hadron physics in high-energy antiproton collisions with fixed hydrogen and nuclear targets.
The PANDA Forward RICH (FRICH) is intended for identification of charged particles with forward polar angles below 5°–10° and momenta from 3 to 15 GeV/c. FRICH will have a multilayer focusing aerogel radiator to achieve the required resolution on Cherenkov angle. A set of precisely aligned flat mirrors will collect light on the multi-anode photomultipliers which are located outside of the detector’s effective aperture. The PANDA Forward RICH R&D relies on experience of other modern RICH detectors. A baseline design of the PANDA Forward RICH is presented including results of the full Monte-Carlo simulation, optical measurements and prototype beam tests.
