    “With demands for more precision both in HEP (High Energy Physics) and in industry, there is considerable research and development concerning precise time and position measurements from a variety of detectors. Resistive Plate Chambers (RPCs) are fast gaseous detectors with high spatial and temporal resolution. They were conceived in 1981 and used to detect charged particles in HEP. Multigap Resistive Plate Chambers (MRPCs) were introduced later to improve the time resolution and they have been used as time-of-flight (TOF) detectors both in HEP and in medicine (PET) . RPCs consist of two parallel plates, a positively-charged anode and a negatively-charged cathode, both made of a very high resistivity material and separated by a gas volume. When a charged particle enters the gas gap it can ionize the gas molecules to create electron-ion pairs. Due to the electric field, the ions travel towards the cathode and the electrons towards the anode, inducing signals on the pickup electrodes. The moving electrons are also subject to an avalanche process, which amplifies the signals. Ultimately, the acquired data provides information such as time-of-flight and position telling us where and when an event occurred. The higher pile-up (interactions per crossing) of future colliders, such as the High Luminosity Large Hadron Collider (HL-LHC), will present new challenges for tracking.”
