A single Time-of-Flight tray based on multigap resistive plate chambers for the STAR experiment at RHIC

The STAR experiment at RHIC plans to implement a 60m2 Time-of-Flight (TOF) system. The Multigap Resistive Plate Chamber (MRPC) is a suitable candidate for the STAR TOF system due to its time resolution of order of 60ps with efficiencies in excess of 97%. We obtained this result with modules composed of 6 gas gaps of 220μm and pad area of 20cm2. In this paper, we report on the performance of this MRPC module and present the current status of the construction and installation into STAR of a prototype tray.
