6. LHC status 6 18/01/2008 Approach Define objectives and prioritize (as usual) Individual System Tests/ Hardware Commissioning  Equipment groups/HWC team Individual high level control tests  From CCC using controls infrastructure and software  Check the functionality of the individual systems Integration tests (dry runs) + HWC/PGC Partial machine checkout Machine Protection commissioning Full machine checkout Try and document it – something we’ll have to do every year

7. LHC status 7 18/01/2008 Approach

8. LHC status 8 18/01/2008 Comments There’s a lot going on the same time This not going to be particularly tidy or particularly easy Accept dry runs as a debugging exercise Accept it won’t be perfect first time Iterate [but at an appropriate frequency] Look for robust solutions that follow established standards.

9. LHC status 9 18/01/2008 Integration Tests (Dry Runs) Multi-system tests to check integration and readiness of all systems involved in a given phase of LHC operations:  Check data acquisition chain  Check all equipment control functionality  Check timing and low synchronization  Check functionality of the control system from CCC high level applications.  Drive all relevant systems in a synchronized way through the standard operational sequence  Check machine protection and interlock systems Organization  Coordinated by Operations. Preparations for, and results of, dry runs to be discussed at LHCCWG.  In close collaboration with equipment groups, technical issues to be discussed in ABCIS meetings.  Seen as a prelude to full system tests to be performed before beam. Debugging – establishing control & integration from the CCC

25. LHC status 25 18/01/2008 Beam Interlock System Complete the IST of the BIS by April.  This will be carried out by the BIS team (independently of the HWC). Perform the Commissioning of the BIS in // with the HWC.  Tricky - involves all LHC systems: Experiments, COLL, VAC, BLM, other Beam Instrumentation, RF, Access, and so on...  BICs are installed either side of IP, done for each one of the 8 points.  8 periods of ~5 days (or twice 2,5 days) during the HWC.  Either inserted before the Powering tests or just after them.  The possibility to have a sector(s) test is going to be taken into account in trying to give priority to points 8, 7 and 6 (or 2,1,8). Perform a final test- dedicated week during the cold-check period. Concerning dry-runs, we have recently installed 2 more BICs in point 6 in order to participate to the LBDS dry-runs in // with our BIS commissioning. The goal is to do NOT disturb our commissioning and move ahead with the interfaces with you, the Timing and the Kickers. c/o Bruno Puccio
