  1. Preparation for Beam commissioning Mike Lamont Acknowledgements: Brennan Goddard, Verena Kain, Reyes Alemany, Gianluigi Arduini, JJ Gras, Stefano Redaelli, Bruno Puccio.

  2. Objectives Get ready for first beam • 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. LHC status

  3. 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. LHC status

  4. HWC - baseline • Cooling and Ventilation • Cryogenics Plant • Cryostat Instrumentation • Electrical Network • Beam Vacuum [warm & cold] • QRL Vacuum • Insulation Vacuum • Powering Interlocks • QPS and energy extraction • QRL Instrumentation • Access • Survey/Alignment LHC status

  5. Incoming this session • Cryogenics • Magnets/circuits • Vacuum • Injection system • Beam Dump System • Collimators • RF • Beam Instrumentation • Machine protection • … Some how pull this lot together to give us a operational machine LHC status

  6. 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

  7. Approach LHC status

  8. 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

  9. Integration Tests (Dry Runs) Debugging – establishing control & integration from the CCC • 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. LHC status

  10. Objectives- Instrumentation LHC status

  12. Objectives - Controls • Slow timing, fast timing, synchronization • Alarms, logging, post mortem, fixed displays • Equipment control & access • Real-time feedback system • Analogue acquisition • Software: measurements, trajectory acquisition and correction, ramping etc. etc. • Controls infrastructure: servers, databases etc. • Software Interlock System • Management of Critical Settings • Role Based Access Control LHC status

  19. Instrumentation • Every BI SW responsible will organize the continuous assessment of its instruments, ie find/organize time slots, also outside official dry runs, where conditions allowing to test functionality [see JJG] • Maintain the dashboard info up to date (color scheme and details on the box dedicated page) and prepare battle field for the next iteration LHC status

  20. Instrumentation - DR 1/3 • Find/organize time slots, also outside official dry runs where conditions allow testing of required functionality • Play simulated injection, ramp etc… • Plus dedicated dry runs LHC status

  25. Beam Interlock System c/o Bruno Puccio • 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. LHC status
