12 days remain in FY06 NSTX Run

• 3.5 days of unallocated time remain
• Very Good progress with MHD and Solenoid-free
  startup milestones.
• Good progress with almost all experiments
• Desirable to make additional progress with High-K
  and Li milestones
• Considering devoting one day to do multiple XPs
  that require about 2-3 hours each.
• Do we need to spend additional time in MHD?
