X. Workshop on Resistive Plate Chambers and Related Detectors

Multi-gap resistive plate chambers (MRPCs) are planar gaseous detector made with resistive electrodes. Such detectors have good time resolution, high efficiency and low cost. These excellent characteristics, as well as the possible coverage of large areas, made MRPCs favorite detectors for high-granularity large-area time of flight (TOF) systems in modern nuclear and particle physics...

The time-of-flight (TOF) system of CBM experiment is proposed to be assembled of multi-gap resistive plate chambers (MRPCs). This system should have a counting rate capability up to 20 kHz/cm2. Usage of low-resistivity glass is a promising way of improving the MRPC rate capability. To address this issue, we produced special silicate glass with bulk resistivity in the order of 10e10Ωcm and...

For the most forward, high rate environment, region of Compressed Baryonic Matter experiment at the future Facility for Antiproton and Ion Research in Darmstadt the installation of timing Resistive Plate Chambers (RPC) is under consideration. Prototype timing RPCs have been developed at Forschungszentrum Dresden-Rossendorf (FZD). RPC electrodes with volume resistivity of about 10^9 Ω⋅cm are...

Resistive Plate Chambers operating at high particle fluxes require the use of materials with a specific set of properties. At present it is believed that the dominant effect, for the case of sustained and homogeneous irradiation, is caused by the product of the plate thickness (d) times its resistivity (r) times the average charge per gap (q), as expected from the dynamic ohmic drop in a...

Aging of glass RPCs has been extensively studied over the last years, with most authors referring effects such as an increase of dark counting rate, reduction of the counter efficiency and the appearance of deposits over the electrodes surfaces. Previous studies have shown that the deposit on both glass electrodes (cathode and anode) is essentially formed by olygomers of tetrafluoroethylene...
