The plans for LHCb upgrade II in the HL LHC era include complementing the experiment’s particle identification capabilities in the low momentum region up to 10-15GeV/c with the novel TORCH time of flight detector. TORCH is designed to provide 15ps timing resolution for charged particles, resulting in K/pi (p/K) particle identification up to 10 (15)GeV/c momentum over a 10m flight path.
We present the results of beam and laboratory test of TORCH prototypes; the latest TORCH design for the LHCb upgrade II Framework Technical Design Report; and the simulated particle ID performance in LHCb upgrade II high luminosity running conditions.
