The present ATLAS RPC system is a 3D+time tracking detector providing the first level trigger in the ATLAS barrel. It is constituted by 6 concentric cylindrical layers providing independent space-time measurements along the track, with 1ns x 1cm resolution. This system will undergo a major upgrade for the HL-LHC program, consisting in inserting in the Inner Barrel region, three additional full...

The improved RPC (iRPC) chambers, designed using thin low resisitivity High Pressure Laminate gaps, are proposed to equip the very forward region of the CMS detector. They can stand rates of few kHz/cm^2. New electronics equipped with excellent timing precision measurement (< 150 ps) has been developed to read out the RPC detectors from both sides of the strips to allow good spatial resolution...

The high luminosity Time-of-Flight (TOF) systems call for timing detectors with both good time resolution and adequate rate capability, which have been fulfilled by the Multigap Resistive Plate Chamber (MRPC) assembled with low-resistive glass electrodes. However, recent tests and operations with high rate MRPCs have given evidence to the luminosity effects, such as the dark current rise and...

Resistive plate chambers (RPCs) are the ideal technology for the instrumentation of muon systems at high-energy particle colliders where excellent subnanosecond time resolution and reasonable spatial resolution of the order of 1 mm are required. Conventional RPCs with planar electrodes have the disadvantage that these cannot be operated at large overpressure. This limitation is overcome by the...

The detailed avalanche, saturated avalanche, and streamer simulation can help understand the detector physics behind the Resistive Plate Chamber (RPC). From a 3D Monte Carlo simulation of an avalanche inside an RPC, the transition from avalanche to saturated avalanche (when electron gain and loss are almost the same) followed by a streamer may be understood in more detail. Such simulation is...

The conventional readout method of the RPC detector uses two sets of orthogonal readout strips placed at the both sides of the gas gap to collect signals of opposite polarities to obtain space points. A new readout method utilizing the reflection signal is proposed which only requires one set of readout strips. The reflection readout method utilizes the differences in the arrival times of the...

We describe a 96-channel Time-to-Digital converter (TDC) and its intended state-machines, implemented in field-programmable Gate Array (FPGA) for the CMS Phase 2 upgrade of the RPC Link System. It is realized as a 6U card, called Link Board and will be used at the High Luminosity LHC (HL-LHC). The TDC system operates at an RPC intrinsic time resolution of 1.56 ns, a minimum input pulse width...

To provide better cluster position resolution a new iRPC with two-ends readout and upgraded LinkSystem in CMS RPC detector will be used to provide timing information together with hit information. Different from present CMS RPC system where a partition has been used in data compression and decompression before data transmission and after reception respectively [1], so a new...

Thin-gap RPCs with 1 mm gap size are introduced in ATLAS upgrade. Smaller avalanche charge due to the reduced gap size raises concerns for signal integrity. Analytical study of signal transmission process in lossless condition is implemented for RPC. Modelling and simulation will be discussed in detail. Simulated characteristic impedance has been compared with the measured value to validate...
