Abstract

The double-stack Multigap Resistive Plate Chamber (MRPC) is the detector chosen for the large Time-Of-Flight system of the ALICE experiment at CERN LHC. The TOF barrel has to cover an area of 160 m² and has to be highly segmented (160.000 readout pads of 2.5×3.5 cm²) in order to keep the occupancy at the 15% level. In this article recent results on several prototype MRPCs are presented, with particular emphasis on the study of the uniformity of these devices.
