RICH detectors
Experiments at accelerator facilities, such as CBM and HADES, each consist of a large number of different subdetectors capable of measuring specific properties. Only by combining multiple subdetectors is it possible to integrate these properties and determine which type of particle was detected. For the analysis of electrons and positrons, a clear distinction from hadrons is necessary, for which the RICH (Ring Imaging Cherenkov) detector is used; our research group has played a key role in its construction for both CBM and HADES. Precisely identified electrons form the basis for the study of dileptons, one of the most promising samples for characterizing the QGP. While HADES has achieved a level of electron purity never before attained thanks to the RICH, the mRICH in the CBM prototype mCBM also demonstrates its functionality for the CBM experiment.
