  1. LHC Installation Status & Master Schedule Content • Global Installation Status • Tour of the LHC: detailed status and plans • Summary Sylvain Weisz - LEMIC

  2. Global Installation Status Sylvain Weisz - LEMIC

  3. Sector 7-8 • All cold elements in place, including DFBAN(7R) & DFBAO (8L) • Interconnections in progress: 8 sub-sectors (out of 14) are completed • Line N cables inserted in Dispersion Suppressor 7R: ELQA Ok • LSS8L • Cold parts • Interconnection DFBAO-HCM/LCM in progress • Interconnections done for low-β/DFBX/D1, Q4-D2/DFBMA, Q5/DFBMC • Warm parts • All components in place (except large beam pipe between D1-D2) • NEG activated in Q4.L8-Q5.L8 sub-sector  10-11 mbar Sylvain Weisz - LEMIC

  4. LSS8 Left Sylvain Weisz - LEMIC

  5. ~2 Wk delay on DFBAP DFBLA on critical path for Sector 8-1 Interconnection ends week 45 3 weeks: global leak and pressure test ELQA and flushing Start cool-down week 51 Let 7-8 floating to Connect 8-1 to QUI Start power tests mid-March 2007 Sylvain Weisz - LEMIC

  6. Sector 4-5 • LSS4R • RF installation in progress: cavities (ACS), damper (ADT) and pick-up (APWL) in place • RF wave guides in place, connection to cavities in progress • Klystron installation in progress • Interconnection D4-Q5/DFBML and Q6/DFBMG in progress • Arc 4-5 and DS • All cryo-magnets (except SSS184) are in place: • SSS184 was reloaded and is now in SMI2 for repair (expected back in place on 29/10) • Interconnections in progress, nominal rate consolidated  Cryostat closed by mid-January • LSS5L • Short circuit tests done in RR53 and USC55 • Low-β, DFBX, D1(6 MBXW), TAN and D2 in place Sylvain Weisz - LEMIC

  7. DFBLD is late for Sector 4-5 Interconnection ends week 02 DFBLD connected for pressure test Start cool-down late March 2007 Start power tests early June 2007 Sylvain Weisz - LEMIC

  8. Sector 5-6 & 6-7 • LSS5R • Low-β, DFBX, D1(6 MBXW) and TAN in place • UJ56-RR57: power converters & energy extraction systems (DQR/DQS) in place  short circuit tests start mid-November • Arc 5-6 and DS • Cryo-magnet transport in progress: 153 MB and 49 SSS in place • LSS6L/LSS6R • UA63: short circuit tests in progress (8th zone out of 15) • US/UX65: installation of QULA in progress • UA67: power converters in place, cabling (AC, DC, Control & Water cooled) in progress • Arc 6-7 and DS • Cryo-magnet installation: 52 dipoles and 26 SSS in place (24/10/2006) No passage through 7-8 & 8-1 from Monday to Thursday due to interconnection work  transport of cryo-dipoles and special SSS during week-ends, arc SSS via UX65 • LSS7L/R • Straight section: all services completed • UJ73 & UJ76: power converters and energy extraction systems in place  short circuit tests start mid-December Sylvain Weisz - LEMIC

  9. No dipole transport from mid-December to January: Cool-down of sector 7-8 (ambiant temp. to 80 K) No time to perform nominal Hardware Commissioning in 2007 4 weeks for cool-down: crude calibration & tuning of cryo. loops 4 weeks for power tests: restrict to injection energy Sylvain Weisz - LEMIC

  10. Sector 1-2 & 2-3 • Sector 1-2 • QRL installation completed: pressure tests scheduled October 28th  QRL work behind us! • Installation of support jacks in progress • LSS2L/LSS2R • Water cooled cables installation in progress in UA23, done in UA27 • Air treatment and cooling units installation close to completion in UA23/27 • Installation of power converters in progress in UA23, done in UA27 • Arc 2-3 and DS • Cryo-magnet installation in progress: 40 dipoles and 6 SSS in place • QRL jumper preparation done • LSS3L/R • Installation of Power Converters in UJ33 completed, PC cabling just started • DSLC (cryogenic power line) installation in progress Sylvain Weisz - LEMIC

  11. Last DFB’s in May 07 Delays installation of low-β in LSS2L Other cryo-magnets in place by March 07 Closure of LHC by end of August 07 (incl. leak & pressure tests) Global operation tests with 7 Sectors in // Preparation for beam 1 week for Sector 1-2 Sylvain Weisz - LEMIC

  12. Main Installation Milestones • End of interconnect in Sector 7-8: week 45 (mid-November) • Start of cool-down of Sector 7-8: week 51 (mid-December) • Start of power tests in Sector 7-8: mid-March 07 • End installation of cryo-magnets (except LSS2L low-β): end of March 07 • LHC Closure (including leak & pressure tests): end of August 07 • End of power tests up to injection energy: mid-November 07 • Ready for beam commissioning at 450 GeV: end of November 07 Sylvain Weisz - LEMIC EDMS document #102509

  13. Summary • QRL: all sectors ready, pressure test of last sector on October 28th • Magnet transport: on track to install most LHC magnets by March 07 (861 MB, 249 Arc SSS and 58 Special SSS in place today) • Interconnection: on-going at nominal rate in 4 sectors  Sector 7-8 closed by mid-November • Installation of power converters (>80%) and short-circuit test (>50%) • DFB delivery: DFBA (4/16), DFBM (10/23), DBX (5/8) • Warm beam-pipe installation in progress in LSS8L/R, LSS1L & LSS4R • 2006 objective: cool-down Sector 7-8 by the end of the year • LHC Master Schedule very challenging and without contingency • Time allocated to cool-down and power tests is too short to achieve a complete hardware commissioning in 2007 Sylvain Weisz - LEMIC
