RPC Signal attenuation and dispersion are interesting topics and become more concerned since thin-gap RPC got popular and new readout methods proposed. Theoretical calculation indicates that attenuation and dispersion exist while signals propagating along the readout strips and both are relating to the surface resistivity of graphite layer and the propagation distance. In simulation we found...
The proposed Iron Calorimeter (ICAL) detector will use approximately 29,000 glass-based Resistive Plate Chambers (RPCs) as sensitive detector elements. A huge 3.7 million electronic channels would be required to read out the full detector. For such a large scale experiment, an optional multichannel front-end ASIC designated as HARDROC has been tested and commissioned with a prototype RPC...
The High-Luminosity Large Hadron Collider (HL-LHC) increases the rate of luminosity in proportion to the rate of the collisions occurring instantaneously. The HL-LHC produces more data and reveals the rare physical events for the purpose of examination. These features of the HL-LHC sets the high-speed transfer of the fast-incoming data to the next layer. The development of the FPGA technology...
The reduction of the average charge per count in the gas along with the capability to discriminate very small avalanche signals, can allow an efficient and long-term Resistive Plate Chamber detector operation, in high radiation background environment. This goal has been reached during the R&D program of the BIS78 ATLAS upgrade project, through the deep integration of a fast (100 ps peaking...
As part of the CMS Phase-II program, new Resistive Plate Chambers (RPC) will be installed in the forward region. High background conditions are expected in this region during the high-luminosity phase of the Large Hadron Collider (HL-LHC), therefore an improved RPC design has been proposed with a new front-end electronics to sustain a higher rate capability and better time resolution. A mixed...
Muon Scattering Tomography (MST) requires tracking detectors with fairly good spatial resolution in order to identify the material contents of the target object from its reconstructed image. A prototype MST set up is being fabricated at SINP using RPC as the muon trackers. Six Bakelite RPCs have been fabricated with pick-up panels equipped with copper strips of width 1 cm to populate the...
A new generation of RPC chambers capable to withstand high particle fluxes (up to 2000 Hz/cm2) and instrumented with a precise timing readout electronics is proposed to equip two of the four high eta stations of the CMS muon system. Doublet RPC detectors each made of two 1.4 mm HPL electrodes and separated by a gas gap of the same thickness are proposed. The new scheme reduces the amount of...
