SMACC Main activities for the last 2 weeks

>98 % done

All shunts are installed

> 95% rewelded

Resoldering completed

DFBAK SHM reconnection on-going [Splices are resoldered],

> 98% reclosed, 12/14 vac subsectors leak tested

Leaks on K hoses repaired, > ½ is finally LT

> 40% done

From last LSC (28.02.2014)DFBAK SHM reconnection on-going [Splices are resoldered], Only the last subesector remains to be leak tested

Completed

> 90% injected and controlled

> 75% reclosed

>95 % of the shunts are installed

Interventions completed, ICs to be reclosed then final LT

1 out of 4 repaired, on-going

Resoldering: Completed for the whole LHC

Some desoldering/resoldering will be necessary because of NCDegradation after Cu machining, non-conformities,…

Competence and minimum capacity will be kept up to the end of the project

In order to alleviate effect of the end of work atmosphere, presence in the tunnel is increased:

* One extra staff (Thx TE-VSC) to second worksite supervisors* Auditors are reinforced and are intensifying audits

SMACC Summary on progress

Main 13 kA Splices: On schedule Q Diodes consolidation :

Almost all components are at CERN and tested Overheated splices : to be followed up closely Leak test rate is according to forecast, slightly more needed

Special Interventions: Delay is decreasinng Almost all planned interventions are completed

Focus on NC DFBA: Activities are back in the shadow of arc splices (except 56-78)

SMACC: About 2 days of delay, reducing

wrt schedule defined one year ago !!

Very slightly more than nominal rate achieved these last 24 weeks !

JPh Tock27/29

Sector 56 : Final leak test and reconnection of DFBAK

Sector 67 : Reclose insulation vacuum and start final leak tests

Sector 78 Work on NC Reconnection of DFBAO-SHM

Sector 81 (Priority) Complete insulation vacuum leak test

Sector 12 (Priority) Reclose last ICs Progress on insulation vacuum leak test

Sector 23 Complete the installation of electrical insulation Complete M line rewelding (but NCs) Progress on M-lines leak testing Start reclosure of ICs

Sector 34 Work on overheated splices Complete consolidation of Q diodes

Sector 45 Progress on installation of shunts Progress on electrical insulation

SMACC Main activities for the next 2 weeks

JPh Tock28/29

ConclusionsProject is almost back on schedule (-2 days)

Mind the last X % effectLeak testing is reaching the planned rates

DFBA consolidation is progressing very well

Overheated splices : On the critical path

S67 is almost ready for next step (ElQA before cooldown foreseen end of April)

S81 should be ready on time for pressure test (8.04.2014)
