【 摘 要 】

A full differential strip readout multi-gap RPC was developed to meet high counting rate and high multiplicity requirements of a high collision rate experiments as Compressed Baryonic Matter at the future FAIR facility. The Multi-Gap, Multi-Strip Resistive Plate Chamber (MGMSRPC) is a completely symmetric two stack structure with time resolution around 50 ps and a detection efficiency better than 95%. A very good efficiency and time resolution at counting rates exceeding the CBM-TOF requirements is obtained using low resistivity (∼ 1010Ωcm) glass electrodes.
