LQ Plan for FY08

• Produce coils, produce coils, and produce coils!• Design & procure instrumentation traces.• Procure long lead magnet parts during the 1st

half of year.• Procure remaining LQ magnet parts in 2nd half

of year as money becomes available.• Prepare for magnet assembly in FY09.

LQ Conclusions

• The tooling length scale up for the LQ is nearly complete.

• Practice winding to begin within the next week.• Long generic tooling used for the LHC

quadrupoles is in place for the LQ practice coils in IB3.

• Valuable experience from moving LM dipole coils and subassemblies can be tapped into for LQ.

LQ & LM Status & Plan for FY08 – Fred Nobrega 13LARP Collab. Meeting – SLAC, Oct. 17-19, 2007

LM Status

• 2m LM01 PIT mirror: Successfully tested to short

sample limit (next page)

• 4m LM02 RRP mirror: Clamps installed last week Shell welding this week Send to VMTF by end Oct.

• Long magnet infrastructure: 100% complete.

LM plans

• Test 4m mirror dipole magnet by end of Oct.• Investigate maximum coil strain.• Determine cause of reaction tooling bow after

heat treatment. » Does it cause degradation?

• Determine impact of tooling bow on LQ coils.

LM Conclusions

• The scale up of the 1m dipole mirrors to 2m using PIT strand was successfully demonstrated.

• The 4m (RRP) mirror magnet is about to be tested and will provide valuable information on coil degradation due to deflection.

• Feasibility of coil handling and subassembly handling is demonstrated with the long dipole mirror.
