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


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.

Incoming this session

Some how pull this lot together to give us a operational machine


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


Approach


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.


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.
