Abstract

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.
