Abstract: Resistive Plate Chambers (RPCs) were introduced by R. Santonico and R. Cardarelli in 1981, are gas ionization chambers made with resistive electrodes separated by precision spacers. Typical gas gap ranges from a few hundred micrometers to several millimeters wide. Timing Resistive Plate Chambers (tRPCs) were introduced in 2000 by P.Fonte, A. Smirnitsky and M.C.S Williams and since then it has reached Time Resolutions better than 50 ps (σ) with efficiencies above 99% for Minimum Ionizing Particle (MIP). In this research paper, we described the main features of gas detectors and the different types of RPCs and their properties. We described the main results that we have got during the operating the sealed tRPCs built in the laboratory.
