ALICE Time of Flight Detectors

by Crispin Williams (INFN, Bologna)

Friday 4 Nov 2011, 11:00 → 12:00 Europe/Zurich

40/S2-D01 - Salle Dirac (CERN)

The Multigap Resistive Chamber has revolutionized Time-of-Flight (TOF) arrays over the last decade. This presentation will briefly cover the need for TOF Arrays and will look at the technology in use at the turn of the century. The ALICE experiment eventually selected a new technology for the time of flight detector : The Multigap Resistive Plate Chamber (MRPC). The exceptional operational characteristics will be discussed together with some key aspects of the physics behind the operation of this detector. The most relevant characteristic of any TOF array is the time resolution; currently the ALICE TOF array achieved a global time resolution of ~ 75 ps. The many contributions that go into this number will be presented with the aim to improve the timing.
