Considerations on progress and planning
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

SMACC Progress report Activities since last LSC
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
JPh Tock10/26
SMACC Progress report Activities since last LSC
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
