Abstract
The double-stack MRPC (Multigap Resistive Plate Chamber) strip is the basic element of the ALICE Time-Of-Flight (TOF) detector. A test of a sample of MRPC strips randomly chosen from two years of mass production (the TOF is made of 1638 strips) was carried out during the autumn of 2006 at the CERN Proton Syncrotron facility. In this paper the most relevant results on the performances of the MRPCs will be presented. The results confirm that these devices have a very good uniformity of response, a long streamer-free plateau, an efficiency higher than 99% and an intrinsic time resolution better than about 40 ps.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
