Superconducting Strand
Procurement Progress 60 order placed on
Outokumpu (Finland) July 08, 1999 40 order
placed on Intermagnetics General Corp (USA)
July 08, 1999 IGC, OKSC Contracts to be
completed Jun/Oct 2000 1st OKSC Article (one
cable) On Time Oct 29, 1999 OKSC 1st Article
(Quality Very Good) Accepted by CMS Dec 13,
1999 1st IGC Article (one cable) 15 wks late
Feb 15, 2000 IGC 1st Article Accepted (Quality
very Poor) by Fermilab Apr 12, 2000 IGC 2nd

OK) Nov 15, 2000 IGC Unable to Complete prior
to Feb 2002, Contract Cancelled Oct 20,
2000 Balance of Work awarded to OKSC Dec 01,
2000 OKSC Modified Contract to be
completed Oct 30, 2001 OKSC Quality Excellent,
Presently Running 1 month late

Aluminum Alloy Reinforcement
  • Aluminum Alloy Procurement Progress
  • Contract (125 tons) Awarded to Alusuisse Swiss
    Aluminum Mar 13, 2000
  • Contract (10 test bars, 40 production bars) to be
    Completed Jun 30, 2001
  • 1st Article (2 300 m short bars) On Time June
    08, 2000
  • 2nd Article (6 2650 m commissioning bars) On
    Time Sept 01, 2000

Where Do These Components Go?
EB Welding (ETHZ/CERN, not USCMS CP)
15
Where Do These Things Go?
Conductor Straightening, Prebending at Ansaldo
(INFN/CERN)

Conclusions
  • Loss of 2nd Vendor for Superconducting Strand
    Removes Luxury of Generous Slack in Strand
    Procurement Schedule Remaining slack now 3
    months
  • 1st Vendors Superconducting Strand is of
    Excellent Quality Responsive to Increased Order
  • Pure Aluminum Quality Excellent Contingent
    Quantity to be Ordered Soon
  • Aluminum Alloy Quality Excellent, Vendor
    Responsive Expected to Complete Successfully
    Schedule has 8 months slack
