Conclusions

JPh Tock4/26

SMACC Main activities for the next 2 weeks Sector 56 :

Continuation of on-going activities (Arcs and DFBAs with restart of broaching)

Restart welding at a substantial speed

Complete electrical measurements on the quadrupole diodes

Sector 67

Complete the opening of the M-lines

Complete the opening of the quadrupole diode containers & start electrical measurements

Perform ElQC on present splices

Sector 78

Continue installation of DN200

Start opening of IC (> 50 % have already W-bellows opened to allow DN200 installation)

Sector 12

Disconnect cryodipoles to be replaced (Rate : 1-2 per week)

(Objective: All 18 cryomagnets disconnected for end of August 2013)

Other sectors:

Special interventions/investigations

Welding restarted in 56, see next slide

Also started in 81 for advanced info on existing splices

Opening of diode containers also in 78

> 70% (#123) are installed

142 ICs are completely opened + 50 W bellows opened

All (#6) are disconnected, starting in S23 (#2)

From last LSC (14.06.2013)

Was presented last LSC by L Grand-Clement

JPh Tock5/26

SMACC Progress report Activities since last LSC

Opened interconnections in 8 sectors, almost equivalent to 4 sectors

Some team members will reinforce ELQC and DN200 activities

ELQC measurements

See R Ostojic’s presentation

Critical NC LHC-QN-QBBI.A21L6-M2-Int-cable

Investigations are on-going (not top priority)

Less critical outlier in S45: Magnetistaion

results shows that there is no significant Ic

degradation. (Detailed report at a further LSC)

Conservative measure:

Investigate other outliers (Open IC,

open M, (enhanced) ELQC but NO

splices desoldering [Limited spare

availability] (Not top priority)

Quadrupole diodes

S56 & 67 opened, 23/51 opened S78

One component (Inconel threaded piece) is expected to be delivered next week

[Delay for starting the actual consolidation, progress on opening diodes containers]

NC corrected, validated by electrical tests

M insulation installation

68 ICs equipped (See issue with interference with M lines) [Was 52 2 weeks ago]

ELQC procedure updated

See Ranko’s presentation

M-welding

18 ICs released beginning of the week. (6 where only M3 has to be welded):

Now 4 remains / 10 were welded this week, not yet controlled

10 more could potentially be released if accepted to come back for diode containers

rewelding and the equivalent of 7 more ICs could be released if individuals lines are

welded: Not the optimum use of welding resources but better than not working

DFBA Consolidation

Broaching incident reproduced in workshop conditions

Courtesy R Principe

LSC 31.05.2013 In workshop, at 318 bars (Now pressure limited at 150 bars)

Damaged splices have been desoldered and are under resoldering

Broaching to restart next week; on the critical path for DFBA consolidation, not (yet) for SMACC

DFBA Consolidation : RCS.A56B2 (DFBAK and 11 other ones)

MP3 recommendation presented by M Modena at last LSC

Proposal was presented and approved by MP3 this week

PEEK protection (optional, 2 halves)

Spacer to avoid overheating (concept)

PEEK protection (2 halves)

Perimetral glass-epoxy foil protection (0.5 mm thickn.)

- function: protection againts wear and insulation if damage- smooth insulating surfaces- minimal thickness to avoid deforming the busbars (≤ 2 mm)- strong and very resistant to wear- avoid overheating (being validated)

SMACC Progress report : Dashboards

Forecast 4 LSCs ago

Concern : Busbar position and consequent interference between M lines and insulation boxNevertheless, 193 ICs are now equipped with shunts (> 90% of a sector)

Welds not yet entered because not controlled

Start shunt installation in sector 67.Is it good news?

SMACC Some considerations on progress and planning

First sign of the «last 10-20% effect» Non-conformities are left behind to keep

good train progress SIT should become free later to solve

these issues In first sectors, margin wrt pressure test,

Coactivity ! Not in the last ones ! One local NC blocks 1 subsector

(214 m / 16 ICs)

JPh Tock21/26

SMACC Some considerations on progress and planning

Main 13 kA Splices: Started a week in advance, now 2 weeks

Special Interventions: 10 days delay: late release of some sectors (45)

DFBA: 1 month delay: Issue with broaching procedure

DN200: > 1 month delay: late release of sector 78 / Start up difficulties

SMACC: 1.5 days advance (but we started one week in advance)

Only completed activities are accounted for, not the on-going ones Weighting factors are based on initial estimates Achieving baseline rates per activity has to be demonstrated

Sequential processFocus on quality first, then production rates

Mind the last 10 % effect (Minimum consequence on first sectors)

JPh Tock22/26

SMACC Main activities for the next 2 weeksSector 56 :Continuation of on-going activities (Arcs and DFBAs with restart of broaching)Continue welding of M lines at an increased rateInvestigate the overheated cable (21L6)

Sector 67Continuation of on-going activities (Arcs and DFBAs with restart of broaching)Perform ElQC on present splices

Sector 78(Almost) complete installation of DN200Complete opening of ICReconnect the disconnected cryodipoles (#2)

Sector 81Open M lines and perform advanced ELQC on about 20 ICs

Sector 23, (34 or 45 depending on access constraints)Disconnect cryodipoles to be replaced (Rate : 1-2 per week)(Objective: All 18 cryomagnets disconnected for end of August 2013)

Other sectors:Special interventions/investigations

JPh Tock23/26

ConclusionsStrategy under implementation for the higher number of splices

to redo (Teams reinforced)Solution ready for DFBA splices broachingMain concerns :

Interference between insulation box and M lines caused by non-nominal busbars position and impact on welding activities

Overheated cables and high R@ 1.9K investigation to define repair procedureCould require replacement of a magnet

Still within schedule, margin decreasedFocus on quality then production ratesLong way to go … on good tracks with a motivated team
