What has to be done …?
To consolidate the superconducting circuits
28th of November 2011
Work Organisation for LS1Second LHC Splice Review
Main splices in the arc DFBA circuits (A Perin) Replace cryomagnets Consolidate connection cryostatsNB: Other activities not linked directly to SC circuits:
PIMs, Helium level gauges, Y lines, DN200, …

The plan is :•Measure and if necessary consolidate the CC 11L8•Consolidate the CC in 11L3 & 11L1•Measure / inspect all the CCs to check no displacement

Work Organisation for LS1Second LHC Splice Review
• PIMs (# 45 to be replaced)
-Buckled during warm-up ≈ 18 (RF ball test) -Heavily damaged : ≤ 10-Preventive replacements :+ Arc extremities 18/32 in baseline
•Consolidation of SAM Helium level gauges and DN160It is planned to consolidate the 2 remaining ones: Q6R2&L8 Support from MME
•Repair of leaking Y-lines
It is planned to consolidate the 2 known cases (S78:17-19R7 & S81:19-22R8)
Was covered in previous slidesPolyvalent teamWill intervene on heavy NC to avoid slowing down the work of the main train
DFBAA Perin [#12
(TBC)]-Splices and BB

Detailed roles
The QA manager will:Coordinate QA activitiesEnsure that an adequate level of Quality Assurance is applied, especially in terms of traceability (MTF) and documentationEnsure a timely management of the non-conformities, minimizing the impact on the overall scheduleEnsure that production parameters are analysed in time to give an early warning in case of drift. Identify as early as possible critical issues that could jeopardize the consolidation work
Quality AssuranceR Ostojic #39
-Electrical QC: C Scheuerlein #17 See presentation-Welding QC: JM DalinOperators, tooling, procedures qualificationQC during production (Visual inspection)Off-line samples-Beam vacuum QC: C GarionProtection and inspection of Bellows, PIMsEndoscopy of beam lines-Open/close IC QC: D BodartVisual inspectionProtection of critical surfaces-QA manager supportTooling, inspection, reporting

Planning
Rate: 4 weeks for each activity so 53 IC/weekDimensioned to 60 IC/week: 10% marginRemember : Series installation at 30 IC/week !
•Closure•Leak tests (Ins vacuum)•Preparation for cool-down•Cool-down
•ELQA@cold
•Powering tests

14 months
1st sector cold tested (2nd one), one year after the start of LS1 !
Consolidation of main splices in 4 sectors in parallel (13 km)

Conclusions
28th of November 2011
Work Organisation for LS1Second LHC Splice Review
• Organisation chart defined and most of the key roles are assigned• Workplan almost defined
DFBA consolidation definition is starting nowResources to be identified
• Most of resources are identified • BUT: Commitments to be kept
To be reviewed with tooling optimization and test
with updated durations
•The production rate (53 IC/week) is ambitious• QA/QC will be implemented to ensure the required quality level• No (very little) margin for extra work, bad surprises 20/20
