  12. SMACC Progress report by activity • M Welding : 410 ICswelded, ≈ 2 sec-eq: • No welding this week to build a buffer of ICs ready to be welded (Announced @ last LSC) • Holes in 56 and 67 will be done next week • Work at a rate of 35-40 IC/week to start next week in 78 (About 70 ICs will be available on Monday), to sustain up to end 2013 • Will be integrated in the overall rebaselining

  13. SMACC Progress report by activity • M sleevesleaktesting : (320 ICs)are leaktested (≈ 1.5 sec-eq) • All possible subsectors of S56 (11/14) are leak tested • 9/14 subsectors are leak tested in 67 • Present situation will be included in the general rebaselining Courtesy P Cruikshank / L Mourier

  14. SMACC Progress report by activity • Reclosure of interconnections : On-going in 67 (priority) and 56 (> 1 sec eq), • 120 ICs are reclosed in 56 and 100 in 67 • Priority is on S67 • Global rate to increase and reachbaseline value with the reinforcement of part of the DN200 team

  16. SMACC Progress report by sector QBQI.18R8 QQBI.27R8 • Main activities are on non-conformities • Overheated cable resoldered, now to be shunted and reinsulated • Uninstall shunts to remove the DFBAK shuffling module • Similarrepair (Sandwich) to beapplied in otherICs Courtesy M Duret, N Dalexandro, P Voisin, R Principe

  17. SMACC Progress report by sector • All non-problematic ICs are shunted, insulated and rewelded • Main activities are the leak test of M lines, the reclosure and the final leak tests • This sector should be the first to be ready for pressure test • Planned to be completely reclosed for end of November

  27. SMACC Dashboards Progress: Baseline: 42.8% (36.3 %) Completed: 36.8% (30.1 %) Delay18 (18) days Stable ; Δbaseline ≈ Δcompleted

  28. SMACC Summary on progress Main 13 kA Splices:  Delay stabilised to 2 weeks Special Interventions:  Delay stable, new activities (DFBAK SHM) DFBA: To be rebaselined DN200: Completed SMACC:  About 3 weeks (stable) Delays are stable Nominal rate achieved these last 5 weeks !

  29. SMACC Main activities for the next 2 weeks • Sector 56 : • Work on non-conformities including installation of all shunts, completion of M welding • Disconnection of DFBAK SHM • Reclosure (not in priority) and final leak test • Sector 67 (Priority sector) • Leak test of M lines • Reclosure of interconnections and final leak tests • Sector 78 • Installation of electricalinsulation • M linesrewelding (35-40 ICs /wk) • Quadrupole diodes consolidation • DFBAs consolidation • Reconnection of Q5L8 • Sector 81 • Desoldering/ Resoldering of splices • Installation of shunts • Other sectors: • S12: ElQC of existingsplices • S23: Open busbarlines • S34: Opening of interconnections • S45: Reconnection of replacingmagnets and opening of diodes containers • Inspection of connection cryostats

  30. Conclusions • DN 200 installation is completed • Repair the overheated cable in 56 completed as planned • Delays are stabilised • Margin has been eaten up for someactivities (M welding, M leak test) • Solution isunderimplementation for the components of the quadrupole diodes • Issues: • Consolidate the splices production rates and increase the rate of installation of the insulationsystemskeepingquality • Impact of repair of DFBA bellows (SIT & Vacsubsectors) So far, not so bad …
