Time reconstruction and performance of the CMS electromagnetic calorimeter
The electromagnetic calorimeter (ECAL) sits at the heart of the CMS detector the LHC. It uses a dense scintillator whose light is detected with fast silicon and vacuum photodetectors. As the detector of high-energy electrons and photons it plays a key role in most CMS physics results, including the Higgs boson discovery paper (Physics Letters B 716 30-61 2012) This paper summarises the design, construction and key operational parameters (0.5% energy resolution, 100ps timing), of the ECAL. I played a major STFC supported role (PP/E000479/1, ST/K001639/1) in the design, testing and monitoring of the industrially produced radiation-tolerant vacuum photodetectors.
