In this wiki page, we document the technical details of RICH-based PID detectors for ePIC experiment.

barrel: compact high-performance DIRC: π/K separation up to ~6-7 GeV/c
h-endcap: dRICH with two radiators (gas + aerogel): π/K separation up to ~50 GeV/c
e-endcap: compact aerogel mRICH: π/K separation up to ~9 GeV/c

Left: 3D model of the EPIC detector with the PID systems indicated. Right: Expected 3 s.d. π/K separation coverage for the ECCE PID systems as a function of the particle momentum and pseudo-rapidity. Full coverage is achieved making use of the veto mode of the Cherenkov detectors that complement PID in the low momentum region

Figure above shows the four PID technologies in a 3D model of the EPIC detector and their coverage 88 as a function of momenta and pseudo-rapidity for a sample of physics event.
