  The ATLAS experiment is one of the multi-purpose experiments at the Large Hadron Collider (LHC), constructed to study elementary particle interactions in collisions of high-energy proton beams. Twelve different sub-detectors as well as the common experimental infrastructure are supervised by the Detector Control System (DCS). The DCS enables equipment supervision of all ATLAS sub-detectors by using a system of 140 server machines running the industrial SCADA product PVSS. This highly distributed system reads, processes and archives of the order of 106 operational parameters. Higher level control system layers based on the CERN JCOP framework allow for automatic control procedures, efficient error recognition and handling, manage the communication with external control systems such as the LHC controls, and provide a synchronization mechanism with the ATLAS physics data acquisition system. A web-based monitoring system allows accessing the DCS operator interface views and browse the conditions data archive worldwide with high availability. This contribution firstly describes the status of the ATLAS DCS and the experience gained during the LHC commissioning and the first physics data taking operation period. Secondly, the future evolution and maintenance constraints for the coming years and the LHC high luminosity upgrades are outlined.

  Muon Reconstruction is a key ingredient in any of the experiments at the Large Hadron Collider LHC. The muon spectrometer of ATLAS comprises Monitored Drift Tube (MDTs) and Cathode Strip Chambers (CSCs) for precision tracking as well as Resistive Plate (RPC) and Thin Gap (TGC) Chambers as muon trigger and for second coordinate measurement. Together with a strong magnetic field provided by a super conducting toroid magnet and an optical alignment system a high precision determination of muon momentum up to the highest particle energies accessible by the LHC collisions is provided. The Detector Control System (DCS) of each muon sub-detector technology must efficiently and safely manage several thousands of LV and HV channels, the front-end electronics initialization as well as monitoring of beam, background, magnetic field and environmental conditions. This contribution will describe the chosen hardware architecture, which as much as possible tries to use common technologies, and the implemented controls hierarchy. In addition the muon DCS human machine interface (HMI) layer and operator tools will be covered. Emphasis will be given to reviewing the experience from the first year of LHC and detector operations, and to lessons learned for future large scale detector control systems. We will also present the automatic procedures put in place during last year and review the improvements gained by them for data taking efficiency. Finally, we will describe the role DCS plays in assessing the quality of data for physics analysis and in online optimization of detector conditions.
