DOIAbstract
International audienceA prototype of a large mosaic MRPC with low resistive glass for the future upgrade of CMS muon system is presented. This prototype is designed by jointing two pieces of glass together and separating them by fishing lines to prevent sparks. A simulation of the weighting field based on Maxwell shows that the efficiency is higher than 90% in the joint area. In a beam test at HZDR, the prototype achieved ~ 92% detection efficiency and about 60 ps time resolution in the joint area, and ~ 95% efficiency and 60 ps time resolution in the active area. A rate capability study shows this prototype can withstand 40 kHz/cm2 at least
