The DIRC-Like FTOF: A Time-of-Flight Cherenkov Detector for Particle Identification at SUPERB;PACS numbers: 29.40.Ka, 29.85.Ca, 29.85.Fj

Abstract

The DIRC-like FTOF detector is a ring imaging Cherenkov counter which uses Time-of-Flight to identify charged particles. A prototype of such device was constructed and installed in the SLAC Cosmic Ray Telescope for timing measurement. A time resolution of about 90 ps/channel was obtained, in agreement with simulation. To estimate the different contributions to the single channel time resolution, a precise simulation of the whole system (detector + MCP-PMT) was written. For this experiment we use the new 10 ps 16-channel USB wave catcher electronics developed by LAL (CNRS/IN2P3) and CEA/IRFU. In this paper, preliminary results of the test ongoing at SLAC are presented. This work is done in collaboration with N. Arnaud, D. Breton, J. Maalmi, V. Puill, A. Stocchi from LAL and D. Aston, J. Va'vra from SLAC. (author)
