Very high momentum particle identification in ALICE at the LHC

We propose to construct and install a limited acceptance detector to identify hadrons (pions, K, p) up to 30 GeV/c on a track-by-track basis in space available in ALICE. Details and PID performance simulation results will be presented for two possible options, including a high transverse momentum (p...

description We propose to construct and install a limited acceptance detector to identify hadrons (pions, K, p) up to 30 GeV/c on a track-by-track basis in space available in ALICE. Details and PID performance simulation results will be presented for two possible options, including a high transverse momentum (pT) trigger for this detector. The first option is a RICH design with a C4F10 gas UV-photon radiator, UV-mirror, quartz window and pad-readout. This design requires additional tracking detectors to enable high pT triggering. A second option is a combination of three detectors: a RICH with CF4 gas both as a UV-photon radiator and as a gas amplification medium (a windowless approach); and a threshold Cherenkov detector (C4F10) with a quartz window and pad readout. The response for minimum ionizing particles (MIP) and UV-photons in these detectors can be well separated. With an additional tracking detector this design will also provide high pT triggering. The simulation includes UV-photon production due to CF4 scintillation.
