摘要：

During 2017, the Large Hadron Collider provided proton-proton collisions up to an integrated luminosity of 50/fb and the Compact Muon Solenoid (CMS) experiment was able to record 90.3% of this data. The electromagnetic calorimeter (ECAL) of CMS was able to achieve excellent data collection efficiency owing to its reliable data acquisition (DAQ) system. The modular and scalar schema followed by the ECAL DAQ system means that ECAL crystals are divided in sectors, each of which is controlled by three interconnected boards. A multi-machine distributed software configures the electronic boards and follows the life cycle of the acquisition process. The increase in instantaneous luminosity during Run II has resulted in an increase in the number of occasional errors due to radiation effects. To combat this, ECAL DAQ has been equipped with automatic recovery procedures and monitoring services.
