Description
The ATLAS Muon spectrometer will be significantly upgraded during the Phase-II upgrade in order to cope with the High Luminosity Large Hadron Collider (HL-LHC). Additional RPC detectors will be installed in the inner barrel layer to increase the acceptance and redundancy, especially under the decreased efficiency of the current RPCs which will exceed their designed longevity then. The new RPC layers are required to have increased rate capability and longevity together with improved performances to meet the severe work conditions under HL-LHC.
R&D work has been carried out at USTC on the thin gap RPC. By reducing the thickness of the gas gaps and of the resistive electrodes, the rate, longevity and time resolution can be improved. The readout panel and method have to be optimized accordingly to match the new gas gap configuration and to improve the spatial resolution. The usage of a much more sensitive Front End Electronics (FEE) will introduce the challenge to the signal-to-noise ratio, the signal induction and propagation process.
In this presentation, the simulation results on the RPC gas amplification procedure and the signal response and propagation process will be reported. These work are very helpful to optimize the RPC work condition and detector design. Some RPC prototypes have been built and tested. The test results will also be presented and discussed.
