Project Description: 

This technology merges the state of the art of Micro Pattern Gas Detector (MPGD) and Resistive Plate Chamber (RPC) technologies in to provide a new class of detectors able to provide high rate capability, exceeding 1MHz/cm2, and simultaneously providing sub nanosecond time resolution. Two classes of solutions are found.

One exploits new materials and techniques in MPGDs to improve by orders of magnitude the rate capability of RPCs, presently limited to O(10) kHz/cm2 due to bulk resistivity of the “resistive plates”.

Another class consists of a very recent micro pattern, the Resistive WELL, where the electrodes for amplification stage are both resistive thereby determining the full transparency of the  produced signals from a series of consecutive amplification stages, yielding a much improved time resolution, which is presently this is limited to 3-5 ns, thanks to the competing processes on each WELL layer.
