Abstract :
The HARP resistive plate chamber (RPC) system was designed for time-of-flight measurement in the large-angle acceptance region of the HARP spectrometer. It comprised 46 four-gap glass RPCs covering an area of 8 m 2 . The design of the RPCs, their operation, intrinsic properties, and system performance are described. The intrinsic time resolution of the RPCs is 127 ps leading to a system time-of-flight resolution of 175 ps. It is argued that gross differences between pion and proton timing in multi-gap timing RPCs, reported recently in the literature, do not exist.
