On the importance of diagnostics

• Diagnostics are essential for JET operation
• Stability (magnetics), plasma position and shape
  control, density control,
• Heating program (Thermocouples, video (hot spots
  deposition), bolometry (plasma radiation))
• Real time control
• Diagnostics are essential for other Task Forces
  and for physicists in
• measuring as many parameters as possible
• providing the best time and spatial resolutions
• providing raw and processed data with quality
  validation by RO
• being adjustable/upgraded for specific scientific
  programs
• -Edge physics, DT campaigns, advanced scenarii,
  divertor physics,

The high quality and diversity of the diagnostic
set on JET the fact that JET is the most
advanced Tokamak on the road to ITER, makes TFD
very unique and important
7
Task Force D tasks

• To continue satisfying these needs Task Force D
  has to
• INFORM
• Ease/promote the access to diagnostic information
  to let people clearly and easily know the
  potential and limitations of all diagnostics
• Encourage seminars in TFD meeting and outside JET
  for both new and existing systems
• Encourage publication and survey the author list
• Provide good quality diagnostic coordinator
  training to optimize JET operation
• Promote JET diagnostics and results
• ENCOURAGE MAINTENANCE
• Promote and ensure good diagnostic maintenance on
  both short and long term (tracability)
• Ensure high quality data production, storage and
  validation

8
Task Force D tasks (II)

• EXPERIMENTAL CAMPAIGNS
• For each JET restart, plan for diagnostic
  restart/commissioning (calibration, alignment )
• Satisfy diagnostic needs during the campaigns in
  term of JET operation with both
  dedicated/parasitic experiments
• Promote a bi-directional constructive
  dialog/coordination between TFs lt-gtTFD lt-gt the
  operator
• Support the TF/JET program in term of diagnostics
  needs
• Ensure the TFD program plan/needs with
  determination and flexibility
• UPGRADE, DEVELOPMENT, ENHANCEMENT
• Estimate and organize diagnostic upgrade as
  required by the scientific program
• Encourage associations to continue
  developing/upgrading diagnostics for JET
• Encourage the use of JET as the best test bed for
  the diagnostic development for ITER
• Identify requirements for probable mid-long term
  physics program

9
Future

• With JET exciting experimental future consisting
  of
• current shutdown
• ITER-Like ICRH antenna installation
• JET-EP diagnostics fully implemented and current
  diagnostic upgrades being performed
• JET-EP2 diagnostics being procured and installed
• future changes in the JET first wall/divertor
• TFD will play a key role and will be a key
  partner for other Task Forces in the scientific
  process to elaborate experimental plans to data
  analysis and to publications
