Description
High Rate Picosecond Photodetectors (HRPPDs) are Micro-Channel Plate (MCP) based DC-coupled photosensors recently introduced by Incom, Inc. that have an active area of 104 mm by 104 mm, pixel pitch 3.25 mm, peak quantum efficiency in excess of 30%, exceptionally low dark count rates and timing resolution on the order of 30-40 ps for a single photon detection. As such, these photosensors are very well suited for Ring Imaging CHerenkov (RICH) detectors that can also provide high resolution timing capability, especially in a configuration where a detected charged particle passes through the sensor window which produces a localized flash containing a few dozens of Cherenkov photons in it.
Recently, a new version of HRPPDs has been developed that were substantially re-designed for use at the Electron-Ion Collider (EIC) , which will be sited at Brookhaven National Laboratory in the US. A first batch of seven “EIC HRPPDs” was manufactured in early 2024. Results of a systematic evaluation of these first EIC HRPPD tiles, including gain and quantum efficiency (QE) uniformity, timing resolution, and dark count rates (DCR) will be the main focus of this talk.
