HHFW Heating into Reversed-shear Plasmas
  • Goal of experiment
    • Apply HHFW power to reversed-shear (RS) scenario
    • Learn about HHFW electron heating under RS condition
    • Compare HHFW to NBI heating
    • Study electron thermal transport
  • Need to
    • Develop target plasma from discharges created for XP-522, e.g. 116978

develop target plasma
Develop Target Plasma
  • Base shot is 116978, DND, L-mode
  • Some development is needed
    • Need rtEFIT control
      • hand shake  0.2 s (Ip flattop start)
    • Shift plasma out  4 cm in order to achieve 4-cm gap
    • Use CS flueling
    • Will need about 3 shots to get there
    • RF camera to ascertain plasma interaction
