CMS Resistive plate Champers

There are many types of gas detectors which are used in CERN in LHC project, There is a main parts for the gas detectors which must be in all gas detectors types like Multiwire proportional chambers, such as the micromesh gaseous structure chamber (the MicroMegas), Gas-electron multiplier (GEM) detector, Resistive Plate Champers... Compact Muon Solenoid (CMS) experiment detecting muons which are powerful tool for recognizing signatures of interesting physics processes. The CMS detector uses: drift tube (DT), cathode strip chamber (CSC) and resistive plate chamber (RPC). Building RPC’s was my project in summer student program (hardware). RPC’s have advantages which are triggering detector and Excellent time resolution which reinforce the measurement of the correct beam crossing time. RPC’s Organized in stations :  RPC barrel (RB) there are 4 stations, namely RB1, RB2, RB3, and RB4  While in the RPC endcap (RE) the 3 stations are RE1, RE2, and RE3. In the endcaps a new starion will be added and this what my group worked on , we almost finished with the first disc for the one of the end caps and one more disc still for the other one. There are stips for building RPC’s and after that the Quality Assurance steps will be applied on the new RPC’s which are:  Leak Test of Gas Gaps and chamber  Spacer test of the gas gaps  High voltage test of Gas gaps and chamber  Visual Inspection of chamber  Cosmic test of chamber  Online Database And also there is experimental steps which I will I will discuss in the report with the testing procedure
