Assemble existing LBL subcoils in open midplane
dipole configuration

• Analysis 2D (and 3D?) forces and fields versus
  size of midplane gap
• Compare to more complete designs
• Use LBL models of subcoils? (ProE used in both
  places) Is this actually a shortcut?
• Instrumentation Use printed circuit strain
  gauges and/or voltage taps now in subscale coils?

open midplane fixture

• Design fixture at BNL
• Iterate with LBL (e.g., tolerances)
• Plan for gt 1 test per fixture
• Begin manufacture in FY05
• Need FY06 funds to complete it, if FY05 holdbacks
  stay in place.
• Understand interaction with design of a model
  separation dipole

4
Base program topics

• Complete 12 T dipole for background field
• 45 turn coil
• React and wind studies
• strain sensitivity of reacted cable (10-turn
  coils)
• stability of cable with high interstrand
  resistivity (short sample tests and 10-turn
  coils)
• Cable test facility
• improvements to short sample fixture
• Vacuum impregnation
• small-scale studies

5
Tasks for the near term

• Apply explore the limits of the technologies to
  FY05 and work on separation dipoles with
  available resources
• Hardware deliverable important
• Make agreements for collaborative work
• Develop resource-loaded schedule
• Milestones budgets task sheets
