Overall TSG objective: Develop and understand non-inductive start-up/ramp-up to project to ST-FNSF operation with small or no Solenoid
Thrust 1 - Establish and Extend Solenoid-free Plasma Start-up
- Re-establish transient CHI discharges utilizing
- Determine maximum toroidal currents generated by CHI
Thrust 2 - Test NBI Current Ramp-up
- Assess NBI coupling + current drive efficiency in 300-800kA flat-top current inductive plasmas
- Use combinations of NBI and HHFW to attempt noninductive ramp-up of Ip = 0.5-0.6MA (inductive target) to 0.8-9MA
Thrust 3 - Ramp-up CHI plasma discharges using ECH, HHFW and NBI and test plasma gun start-up
- Maximize the levels of CHI-produced plasma currents
- Extend duration of high-current CHI target using ECH/ HHFW and test effectiveness of NBI coupling to CHI-target
- Ramp-up of CHI target + ECH/HHFW and HHFW+NBI
- If guns ready, commission and test on NSTX-U
