Description
We report on the result of the R&D activity focused on the development of a Multi-Gap Resistive Plate Chamber with Multi-Strip readout architecture, for high counting rate and multiplicity environment, specific for high interaction rate experiments.
An innovative chamber design which fulfills simultaneously two requirements for strip readout MRPCs, i.e. the granularity and the impedance matching to the front-end electronics, will be presented. The results obtained with this prototype in two in-beam tests performed at CERN-SPS in both triggered and trigger-less/free streaming readout mode operations will be reported.
The performance in terms of efficiency, time resolution, cluster size, and two-dimensional position resolutions in conditions of exposure of the whole active area of the chamber to high flux and high multiplicity reaction products will be discussed. The obtained results recommend such an architecture as solution for large area detectors with accurate simultaneous measurement of time and position in high energy experiments.
