NSTX Macrostability TSG: rev. Bt mtg. 7/16/09 – SAS / SPG

Macrostability TSG shots should run early in rev. Bt campaign, mainly to support other XPs

• Essentially, perform tasks to adjust systems used by experiments Will also add physics results to XPs (902, 933, 934)

• Re-optimize n = 3 error field correction IRWM scans similar to XP902 n = 3 EFC experiment (2 hours: XP902)

• Re-optimize n = 1 active RWM control Feedback phase scan, re-zeroing, etc. in rev. Bt (2 hours: XP934)

• Examine plasma rotation braking in rev. Bt

Superbanana NTV not expected to change – no large scans needed Take about four shots with n = 3 magnetic braking, compare to

normal Bt operation for differences (1 hour: XP933 NTV experiment)

• Total time allocation: 5 hours (1/2 of a long run day)
