The surface Resistive Plate Counter (sRPC): an RPC based on MPGD technology

Abstract The Surface Resistive Plate Counter (sRPC) is a novel RPC based on surface resistivity electrodes, completely different concept with respect to traditional RPCs that use electrodes characterised by volume resistivity. of the sRPC exploit well-established industrial Diamond-Like-Carbon (DLC) sputtering technology thin (50 μm) polyimide foils, already introduced in manufacturing resistive MPGDs such as μ-RWELL and MicroMegas, allows realise large area (up 2 × 0.5 m ) spanning over several orders magnitude (0.01 ÷ 10 GΩ/□). Two detector layout has been developed: baseline DLC connected HV single dot connection outside active high rate screen printing conductive grid onto film, which density current evacuation scheme first for μ-RWELL. Besides HEP experiments timing this new could be exploited thermal neutron device homeland security applications (e.g. Radioactive Portal Monitors ports airports), replacing one or both plates coated ∼3 μm thick B 4 C layer, thus obtaining converters inside detector. Results obtained irradiating detectors at calibrated 241 Am-B ENEA-Frascati HOTNES facility will discussed.
