  11. FMCM: Overview Application • Protection against fast magnet current changes after powering failures • Hw based on DESY version. Main changes are: • Controls interface for supervision and PM readout • Connection with Beam Interlock System • TL/LHC mode selection • 12 monitors in the LHC: • D1 in IR1 and IR5 • Dump septa in IR6 • RD34, RQ4 & RQ5 in IR3, IR7, etc… • Monitoring via Serial link & VME Communication card (VIPC 626) Ethernet Technical Network VME crate Beam Interlock Controller VIPC626 CPU RS422 link FESA class + Existing driver for VIPC626 BIS

  12. FMCM Readiness • 25 units out of 30 received from DESY and tested at CERN. ( 5 more to come) • Corresponding controls software is in place • System ready for installation (in March) • 17 units of the DESY version will also be purchased as backup solution for additional installations.

  18. BIS: Readiness • 17 out 17 BICs for LHC ring BIS are installed • 2 Controllers for Injection BIS as well • 90% CIBU already installed (waiting for access for the remainder) • 95% cables tested (waiting for access for the remainder) • IST is pending => F.O. not yet installed • TS/EL working on it with the highest priority…

  19. Outline • Machine Interlocks = 5 systems managed by AB/CO • Hardware readiness for: • Powering Interlock System • Warm magnet Interlock System • Fast Magnet Current change Monitor System • Safe Machine Parameters System • Beam Interlock System • Commissioning plans for the BIS • State of the supervision for the 5 systems • Summary

  20. BIS Commissioning Phases BIS installation and commissioning: a 3 phase programme • Complete the IST of the BIS by April • generally speaking: independent of the HWC. • Perform the Commissioning of the BIS in parallel with the HWC. • As BICs are installed on each side of an IP => done for each of the 8 points. • Test each link in involving the different USER SYSTEMS • Perform a final test with all players (includes LBDS, Beam Sequencer and Timing) Participation in Dry runs: • Installed 2 more BICs in Pt 6 for LBDS dry-runs in parallel with BIS commissioning. • Goal: permit BIS commissioning + also test interfaces with Kickers, SEQ & Timing.

  28. BIS Commissioning Schedule • Time allocation for phase 2: • Allocate 8 periods of ~5 days (or twice 2,5 days) during the HWC. • These slots will be either just before or just after sector powering tests • Sequence not important: Priority to Pts 8, 7 and 6 in case of Sector test fallback • Proposal still in discussion with the planning team • Expect these slots to be in May/June (It depends on HWC progress). • Time allocation for phase 3: • Need a dedicated week during the cold-checkout period • See Jan Uythoven’s talk (“Machine Protection” in Session 4)

  37. Wrapping up • MI Systems = Technical solutions well established and tested • PIC & WIC : ready for completing the Powering tests • FMCM: ready for commissioning • SMP: First version ready for beam operation • Final version (Hw + Application) in 2009 • BIS will be ready for Beam Operations • Hw in place. IST temporarily stopped. • Controls Sw in place. Need effort on IPOC. • Faced to a Challenging Commissioning • Profit for past experience in TL & in SPS • Fruitful collaboration with OP & MPSC Working Group
