| Abstract | For the identification of particles in the momentum range 0.5-2.5 GeV /c, the ALICE experiment uses a Time Of Flight array consisting of Multigap Resistive Plate Chambers (MRPC) in the form of long strips. The design of the detector elements is as follows: double stack MRPCs with glass resistive plates and 5 gas gaps of 250 mum per stack. The latest results on the performance of these MRPCs are presented. Typical values of time resolution sigma are better than 50 ps, with an efficiency of 99.9% and a long, more than 1.5kV, streamer-free plateau. |
