Description
The proposed high-energy high luminosity polarized Electron Ion Collider (EIC) will, for the first time, enable three-dimensional (3D) precision imaging of the internal structure of protons and atomic nuclei, revolutionize our understanding on quantum chromodynamics (QCD). The EIC physics program demands excellent tracking resolution and particle identification (PID) coverage over a wide range of momenta to achieve the highest precision.
This talk will report the status of the imaging Cherenkov techniques (dRICH, mRICH and DIRC) considered for proposed EIC detector concepts for momentum coverage up to 50 GeV/c. An important challenge for EIC-PID is to provide a reliable highly pixelated photosensor working in high radiation and high magnetic field environment. The recently commercialized Large Area Picosecond Photo-Detector (LAPPD) provides a promising low-cost photosensor solution for the EIC imaging Cherenkov sub-systems. Improvement on the detector design for high magnetic field tolerance, fast time resolution and pixelated readout were performed at Argonne National Laboratory with small form factor MCP-PMT/LAPPDs. The improved design parameters can be directly adapted by industrial partners for low-cost LAPPD fabrications to achieve the required performance.
