A Multigap Resistive Plate Chamber built with thin low-resistive glass: High rate capability with excellent time resolution
/ Liu, Z (CERN ; World Lab., Geneva) ; Williams, M C S (CERN ; Gangneung-Wonju Natl. U. ; INFN, Bologna ; Bologna U.) ; Zichichi, A (CERN ; INFN, Bologna ; Bologna U. ; Enrico Fermi Ctr., Rome) ; Zuyeuski, R (World Lab., Geneva ; Enrico Fermi Ctr., Rome)
Two Multigap Resistive Plate Chambers (MRPCs) were built with thin (0.4 mm) low-resistive glass sheets for the inner plates and standard 0.28 mm ‘soda lime’ float glass as external plates. The 6-gap MRPC reaches 96.5% efficiency at 15.6 kV and a time resolution of 68 ps at an instantaneous particle flux around 2.5 kHz/cm 2 . [...]

Multigap Resistive Plate Chambers (MRPCs) are often used as time-of-flight (TOF) detectors for high-energy physics and nuclear experiments thanks to their excellent time accuracy. For the Compressed Baryonic Matter (CBM) TOF system, MRPCs are required to work at particle fluxes on the order of 1–10 kHz/cm$^2$ for the outer region and 10–25 kHz/cm$^2$ for the central region.
