The multigap resistive plate chamber as a time-of-flight detector

Abstract The goal of this R&D has been to reach the time resolution needed for Time-of-Flight detectors using the Multigap Resistive Plate Chamber (MRPC). We present here a MRPC with a time resolution of 70 ps. This prototype has been studied within the R&D program for the very large area TOF array of the ALICE experiment at the CERN LHC.
