文摘

The time-of-flight (TOF) system of the CBM experiment is proposed to be assembled of Multi-gap Resistive Plate Chambers (MRPCs). A strip MRPC prototype with low-resistive silicate glass electrodes (bulk resistivity ?0¹⁰ ¦¸ cm) was developed suited for the high rate (up to 20 kHz/cm²) applications of CBM-TOF. Beam tests performed at GSI indicate time resolutions of about 70 ps with efficiencies larger than 95 % . The beam position scan shows a crosstalk less than 25 % .
