Description
In the proposed Electron-Ion Collider (EIC) experiments, particle identification (PID) of the final state hadrons in the semi-inclusive deep inelastic scattering allows the measurement of flavor-dependent gluon and quarks distributions inside nucleons and nuclei. An EIC PID consortium (eRD14 Collaboration) has been formed for identifying and developing PID detectors using the Ring Imaging Cherenkov (RICH) technique for the EIC experiments. A modular Ring Imaging Cherenkov (mRICH) detector has been designed for particle identification in the momentum coverage from 3 GeV/c to 10 GeV/c. The first prototype of this detector was successfully tested at Fermi National Accelerator Laboratory in April 2016 for verifying the detector working principles. The mRICH detector consists of an aerogel radiator block, a Fresnel lens, a mirror-wall and a photosensor plane. This talk will highlight the mRICH beam test results and the comparison with the results from a Geant4-based detector simulation. An implementation of the mRICH detector concept in the forward sPHENIX experiment at BNL will also be presented in this talk.
