Safely, Safely, Safely

• ESH Issues (J. Levine) -
• Heath/Safety is the foundation of what we do!
• NSTX Outage is coming to close soon. Please be
  mindful of safety when you may be trying extra
  hard to get ready for the run!
• NSTX Operation is starting soon. Again, please
  be as you enter the test cell. The radiation
  requirement will change so please be ready with a
  proper radiation badge and with appropriate
  training completed.
• The winter is fast approaching (if not here
  already)! Be very careful with slippery surfaces
  when you are outside. Do not forget to put salt
  on your home walkways and driveways when frozen
  condition occur! Keep yourself in good physics
  condition through occasional light exercise.

NSTX Upgrades

• NSTX preparing the mission needs (CD-0)
  material for the NSTX major upgrade (new
  Center-stack and the second NBI) for OFES/DOE
• A visit to Germantown on Dec. 3, 2008 to give
  an update on the NSTX upgrade CD-0 planning
• OFES/DOE requested an NSTX upgrade CD-0 document
  containing combined CS and NBI scopes at the
  earliest possible time.
• Draft Upgrade Schedule Aiming to be ready in
  FY 13-14 (CD-4)
• CD-0 (Mission needs) - ASAP FY 09
• CD-1 (CDR) - Late FY 09 (or early FY 10)
• CD-2 (PDR) - FY 10
• CD-3 (FDR) - FY 11
• Important points made
• Comprehensive up front design and RD for
  realistic cost and schedule
• Adequate cost and schedule contingency
• Identify risks early

Modular design of NSTX enables removal of present
CS and replacement with a new higher-performance
CS

• Present CS has been removed and re-installed
  several times for maintenance and modifications
• New CS would have larger radius for increased
  conductor area and toroidal field current, while
  maintaining low aspect ratio A ? 1.5
• Construction tolerance requirements are similar
  to present NSTX CS

An NBI heating system available from TFTR could
be moved to the NSTX test cell and installed
next to the present NBI

• PPPL has extensive experience operating,
  maintaining, refurbishing NBI
• NBI is well understood and has provided reliable
  heating to high b values in NSTX

NSTX Schedule

• NSTX FY 09 run of 14 run weeks will be
  completed in June and resume operation in
  late-Sept. / early Oct. time frame.
• We will start the run in mid-Feb (Al, Mike
  Bell).
• Jon to issue a research planning guidance for
  the FY 09 run and the first phase of the FY 10
  run with LLD and BES for the research forum.
• The 2009 summer outage period will be minimized
  as much as possible to allow return to operation
  with LLD, BES and MSE-LIF in later
  September/early October. We will need everyone's
  help and cooperation!
• A realistic LLD/BES/MSE-LIF installation
  schedule needs to be developed.
• We will do minimum diagnostic calibration (only
  those which are absolutely needed.)
