PROPOSAL ITPA-IOS / 2012 :

Integrated Magnetic and Kinetic Profile Control

  • Author: D. Moreau
  • Key persons: to bedefined
  • Devices: DIII-D + other machines withinterest in profile control (pleasevolunteer !)
  • Background:
  • A genericmethodology has been developed for system identification and model-basedprofile control on anytokamak, withanyactuators, magnetic and kinetic profile measurements. The methodologyhas been applied on JET, JT-60U and DIII-D, and has a large potential for magnetic and kinetic profile control in non-inductive, high-bootstrap-fraction discharges.
  • First closed-loopmagnetic+kinetic control experiments have been successful on DIII-D. It is important to do more experiments on DIII-D and to startsimilarexperiments on differentdevices, withdifferent sets of actuators and profile measurements tofullyqualifyprofile control methods.
  • Proposal:
  • In 2012, more control experimentswillbeproposed on DIII-D, withdifferentcontrollers, differentcurrent profile targets and bNtargets, using the new off-axis beamcapability and including control of the plasma rotation and ion temperature profile.
  • Otherdevices are contributingto thisactivity (TCV) and mayparticipate. AlsodevicesusingLHCD as a current drive actuatorhave showninterest in 2011 : e.g. AlcatorC-Mod, Tore Supra).
  • Whatabout JET, ASDEX-UG, EAST, KSTAR, etc … ?).
  • Modelling of integrated control experiments (e.g. DIII-D) as well as simulations for future devices (ITER, JT-60SA ?) willalsobeperformed in parallel.
