Plans for Electron Bernstein Wave and Electron Cyclotron Heating in NSTX
2007
A 200 kW, 28 GHz system for electron cyclotron heating (ECH) and electron Bernstein wave heating (EBWH) is being installed on NSTX to assist solenoid‐free startup, high harmonic fast wave heated current ramp up, and to support initial EBW coupling and heating studies. This system will provide on‐axis second harmonic ECH/EBWH in NSTX. Fundamental on‐axis heating may also be possible at 15.3 GHz by operating the gyrotron in a lower order TE01 cavity mode. Sufficient power supply capability will be provided to provide up to 1 MW of gyrotron power for future proof‐of‐principle EBWH experiments on NSTX. Initial modeling of an NSTX startup discharge with 28 GHz ECH is presented.
