DESCRIPTION:Talk Title: "A Proximity-Focusing RICH Detector for the ePIC E
 xperiment at the EIC"\n\nAbstract: The Electron-Proton/Ion Collider Exper
 iment (ePIC) will be a large\, multi-purpose detector to be installed at 
 the Electron-Ion Collider (EIC) being built at Brookhaven National Labora
 tory. As robust particle identification (PID) capabilities are essential 
 for fully realizing the EIC science program\, ePIC contains several PID s
 ubsystems spanning different angular ranges. PID capability in the electr
 on-going endcap is provided by a proximity-focusing Ring Imaging Cherenko
 v detector (pfRICH) designed to deliver 3-sigma separation between pions 
 and kaons for momenta up to 7 GeV/c. It will also aid with electron-hadro
 n discrimination at low momentum and assist in the determination of the c
 ollision time (t0).\n\nThe pfRICH design consists of a cylindrical vessel
  130 cm in diameter and approximately 49 cm in length. The face closest t
 o the interaction point holds aerogel tiles (n = 1.04) which serve as the
  radiator\, while the opposite face contains the photosensors. The baseli
 ne photosensors are the High-Rate Picosecond Photon Detectors (HRPPDs) by
  Incom\, which combine a large\, finely pixelated\, active area (104x104 
 mm2\, 32x32 pixels)\, high quantum efficiency (peak values greater than 3
 0%)\, low dark count rate (hundreds to several kHz/cm2)\, and very good s
 patial and temporal resolution. In particular\, single photon timing reso
 lutions of 15 to 20 ps will enable a precise t0 measurement and ai\n\nhtt
