Beam tests of a large-scale TORCH time-of-flight demonstrator
The TORCH time-of-flight detector is designed to provide particle identification in the momentum range 2−10GeV∕c over large areas. The detector exploits prompt Cherenkov light produced by charged particles traversing a 10mm thick quartz plate. The photons propagate via total internal reflection and...

| description | The TORCH time-of-flight detector is designed to provide particle identification in the momentum range 2−10GeV∕c over large areas. The detector exploits prompt Cherenkov light produced by charged particles traversing a 10mm thick quartz plate. The photons propagate via total internal reflection and are focused onto a detector plane comprising position-sensitive Micro-Channel Plate Photo-Multiplier Tubes (MCP-PMT)detectors. The goal is to achieve a single-photon timing resolution of 70ps, giving a timing precision of 15ps per charged particle by combining the information from around 30 detected photons. The MCP-PMT detectors have been developed with a commercial partner (Photek Ltd, UK), leading to the delivery of a square tube of active area 53×53mm 2 with a granularity of 8×128pixels equivalent. A large-scale demonstrator of TORCH, having a quartz plate of dimensions 660×1250×10mm 3 and read out by a pair of MCP-PMTs with custom readout electronics, has been verified in a test beam campaign at the CERN PS. Preliminary results indicate that the required performance is close to being achieved. The anticipated performance of a full-scale TORCH detector at the LHCb experiment is presented. |
