Analyses of HB, HE, HO and HF calorimeters of CMS detector with 2015 cosmic data and proton–proton collision data at √s = 13 TeV

In 2015, the CMS detector took cosmic muon and proton-proton collision data at √s = 13 TeV. General performance, such as energy and time structure of the HCAL which is one of the sub-detectors of the CMS was controlled with those data. The HCAL should have a good energy and time resolution. So, energy and time distributions of all sub-systems (HB, HE, HO, HF) of HCAL should be controlled regularly. One of the methods used to do these controls is, to benefit from the cosmic ray muon data which is recorded when there is no collision in the detector. The CMS detector is constantly exposed to cosmic muon rays which come from outer space. Cosmic muon rays hit various part of the CMS detector and create signals in the various sub-systems of CMS. So, these data allow to test and calibrate all detector components. The response of the CMS detector to cosmic muons was measured using cosmic muon data (MWGR, CRUZET and CRAFT) which were taken at different time periods. Before the collision data, Beam Splash data were also taken. During beam splash data taking, the CMS detector is exposed to dense particle flow and the response of each sub-system of the detector is investigated. Beam Splash data are very important for performance information of the sub-systems of the HCAL. The CMS detector was prepared for the collision data with the beam splash data. After the two-year technical stop the CMS detector started to take proton-proton collision data at a center of mass energy of √s = 13 TeV. The performance analysis studies of the CMS detector were also performed using this collision data. In this thesis general performance analysis of HCAL systems was carried out using cosmic muon and proton-proton collision data.
