Description
The surface Resistive Plate Counter (sRPC) is a new RPC based on surface resistive electrodes realized with Diamond-Like-Carbon sputtered on Apical® foil. Exploiting high granularity current evacuation schemes developed for resistive MPGD and using electrodes with surface resistivity from 1 GΩ/□ down to 100MΩ/□, sRPCs standing particle fluxes up to 1 - 100 kHz/cm2 should be easily developed.
At the moment prototypes with electrode resistivity > 1GΩ/□ have been tested, exhibiting high stability and good performance in terms of efficiency (∼ 95%) and time resolution (∼ 1ns). A high-rate layout with ρ ∼ 7GΩ/□ and 1 cm current evacuation pitch showed a rate capability with m.i.p. of ∼ 3kHz/cm2.
The scalability of the technology allows the construction of detectors for large area applications at future high luminosity colliders.
