Performance of the CMS Detector During the LHC Run 2

摘要

With the restart of the LHC operations in April 2015, the Run 2 hasstarted. For the CMS Collaboration [1], the second half of the year wasdriven by an intense activity mainly ongoing on three fronts: analyses basedon Run 1 data, studies for the upgrade of the detector in view of the futurephases of the LHC and, of course, collect and analyse proton–proton andheavy ions data. This paper focuses on the latter highlighting exampleswhere the intervention completed during the LHC Long Shutdown 1 (LS1)concretised in an improvement of the performance for the CMS detector andits hardware and software infrastructure.
