CMS RPC data taking during the LHC Run-2 and activities during Long Shutdown 2

The CMS experiment collected around 150 fb$^{−1}$ of proton-proton collision data at TeV during the Run-2 data taking period of LHC. The CMS RPC system provided redundant information for robust muon triggering, reconstruction and identification. To ensure stable data taking, the CMS RPC collaboration has performed detector operation, calibration and performance studies. After the end of Run-2, it was started the second LHC long shutdown period (LS2), an important opportunity for maintenance and preparation for the next data taking period (Run-3) and the installation of services in preparation for the Phase-II upgrade. The activities included maintenance of power, gas and online systems. In this presentation, the overall performance of the CMS RPC system during the Run-2 period is summarized as well as all the activities done in preparation for future data taking periods.
