The CMS electromagnetic calorimeter (ECAL) is a high-resolution, hermetic,and homogeneous calorimeter made of 75,848 scintillating lead tungstatecrystals. Following the discovery of the Higgs boson, the CMS ECAL is at theforefront of precision measurements and the search for new physics in data fromthe LHC, which recently began producing collisions at the unprecedented energyof 13 TeV. The exceptional precision of the CMS ECAL, as well as its timingperformance, are invaluable tools for the discovery of new physics at the LHCRun 2. The excellent performance of the ECAL relies on precise calibrationmaintained over time, despite severe irradiation conditions. A set ofinter-calibration procedures using different physics channels is carried out atregular intervals to normalize the differences in crystal light transparencyand photodetector response between channels, which can change due toaccumulated radiation. In this talk we present new reconstruction algorithmsand calibration strategies which aim to maintain, and even improve, theexcellent performance of the CMS ECAL under the new challenging conditions ofRun 2.
