Publication abstract: 

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. PANDA FRICH will feature a multilayer focusing aerogel radiator, photon detection by Hamamatsu H12700 MaPMTs read out by DiRICH front-end electornics. Precisely aligned flat mirrors will collect Cherenkov light on the photon detector. Results of optical measurements of the detector components are presented. The PANDA Forward RICH prototype was tested at 3GeV electron beam at the Budker INP in 2019. Single photon resolution was obtained that agrees with expectations.
