  1. ALICE DCS project L.Jirden 22.11.01 • Goals and global requirements • Project Organization • System overview • Status today • Conclusion ALICE DCS overview - L.Jirdén

  2. DCS/ECS PROJECT GOALS • High level goal “A working DCS ready for exploitation early 2006 allowing to control and operate the experiment during all modes of operation and according to defined requirements”. • Intermediate goals • System tests and test-beams • Pre-assembly • Installation • Commissioning ALICE DCS overview - L.Jirdén

  3. Main requirements • Integrate all activities necessary to operate the experiment • All detectors and infrastructure during runs and shutdowns • Easy to operate • 2 – 3 non-expert operators should be enough • Exclusive and concurrent operation • Allow for multiple operators • Individual operation of detectors and sub-systems • Access at all levels with unique access control • Automation • Standard procedures, learning system ALICE DCS overview - L.Jirdén

  4. Requirements cont. • Modular, scalable and flexible • Allow for changes and addition of devices, sub-systems or detectors • Reliable • Operational during runs and shutdowns • Redundancy for critical functions non-accessible during runs • Maintainable • Assume 15 years operation ALICE DCS overview - L.Jirdén
