Preparation for Beam commissioning
Mike LamontAcknowledgements: Brennan Goddard, Verena Kain,Reyes Alemany, Gianluigi Arduini, JJ Gras, Stefano Redaelli, Bruno Puccio.
LHC status 218/01/2008
Objectives
All required hardware systems tested All required instrumentation deployed and tested Machine Protection system tested & qualified. All software deployed and required functionality tested Control system integrity tested Full integration tests performed with all systems driven
through operational cycles
Clear that when we finally get beam we don’t want to waste time solving problems that could have been resolved before.
Get ready for first beam
LHC status 318/01/2008
Conditions
Cool-down of remaining sectors Extensive Hardware Commissioning of circuits Installation of remaining components Individual system commissioning Roll out of controls infrastructure Roll out of beam interlock system Roll out of beam instrumentation Software development and deployment, roll out of
magnet model etc… Commissioning of access system (DSO tests etc.) While starting-up and operating SPS/PS etc.

Some how pull this lot together to give us a operational machine
LHC status 618/01/2008
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
LHC status 718/01/2008
Approach
LHC status 818/01/2008
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.
LHC status 918/01/2008
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

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.
