Performance of the new DAQ system of the CMS experiment for run-2
/ André, Jean-Marc (Fermilab) ; Andronidis, Anastasios (CERN) ; Behrens, Ulf (DESY) ; Branson, James (UC, San Diego) ; Brummer, Philipp (CERN) ; Chaze, Olivier (CERN) ; Contescu, Cristian (Fermilab) ; Craigs, Benjamin G (CERN) ; Cittolin, Sergio (UC, San Diego) ; Darlea, Georgiana-Lavinia (MIT) et al.
The data acquisition system (DAQ) of the CMS experiment at the CERN Large Hadron Collider (LHC) assembles events at a rate of 100 kHz, transporting event data at an aggregate throughput of more than 100GB/s to the Highlevel Trigger (HLT) farm. The HLT farm selects and classifies interesting events for storage and offline analysis at an output rate of around 1 kHz. [...]

The CMS Data Acquisition - Architectures for the Phase-2 Upgrade
/ Andre, Jean-Marc Olivier (Fermilab) ; Behrens, Ulf (DESY) ; Branson, James (UC, San Diego) ; Brummer, Philipp Maximilian (CERN) ; Chaze, Olivier (CERN) ; Cittolin, Sergio (UC, San Diego) ; Contescu, Cristian (Fermilab) ; Craigs, Benjamin Gordon (CERN) ; Darlea, Georgiana Lavinia (MIT) ; Deldicque, Christian (CERN) et al.
The upgraded High Luminosity LHC, after the third Long Shutdown (LS3), will provide an instantaneous luminosity of $7.5\times10^{34}$ cm$^{-2} s^{-1}$ (levelled), at the price of extreme pileup of up to 200 interactions per crossing. In LS3, the CMS Detector will also undergo a major upgrade to prepare for the phase-2 of the LHC physics program, starting around 2025. [...]

New operator assistance features in the CMS Run Control System
/ Andre, Jean-Marc Olivier (Fermilab) ; Behrens, Ulf (DESY) ; Branson, James (UC, San Diego) ; Brummer, Philipp Maximilian (CERN) ; Chaze, Olivier (CERN) ; Cittolin, Sergio (UC, San Diego) ; Contescu, Cristian (Fermilab) ; Craigs, Benjamin Gordon (CERN) ; Darlea, Georgiana Lavinia (MIT) ; Deldicque, Christian (CERN) et al.
During Run-1 of the LHC, many operational procedures have been automated in the run control system of the Compact Muon Solenoid (CMS) experiment. When detector high voltages are ramped up or down or upon certain beam mode changes of the LHC, the DAQ system is automatically partially reconfigured with new parameters. [...]

The Detector Control System (DCS) of the Compact Muon Solenoid (CMS) experiment ran with high availability throughout the first physics data-taking period of the Large Hadron Collider (LHC). This was achieved through the consistent improvement of the control software and the provision of a 24-hour expert on-call service. [...]
