Abstract

The TORCH time-of-flight detector will provide particle identification between 2-10 GeV/c momentum over a flight distance of 10 m, and is designed for large-area coverage, up to 30 m². A 15 ps time-of-flight resolution per incident particle is anticipated by measuring the arrival times from Cherenkov photons produced in a synthetic fused silica radiator plate of 10 mm thickness. Customised Micro-Channel Plate Photomultiplier Tube (MCP-PMT) photon detectors of 53 × 53 mm² active area with a 64 × 64 granularity have been developed with industrial partners. Test-beam studies using both a small-scale TORCH demonstrator and a half-length TORCH module are presented. The desired timing resolution of 70 ps per single photon is close to being achieved.
