A high power, high particle flux rf‐based helicon plasma source has been constructed at ORNL and operated at power levels up to 30 kW. High‐density hydrogen and helium plasmas have been produced. The source has been designed as the basis for a li

Existing linear plasma materials interaction (PMI) facilities all use plasma sources with internal electrodes. An rf‐based helicon source is of interest because high plasma densities can be generated with no internal electrodes, allowing true stead

Thermal electron emission at 28 GHz has been measured on the TJ‐II Stellarator. The microwave emission from over‐dense neutral beam heated plasmas, where the plasma density is greater than the ordinary‐mode (O‐mode) cutoff density (>1.2×1019

A goal in the 5‐year plan for the fast wave program on DIII‐D is to couple a total of 3.6 MW of RF power into a long pulse, H‐mode plasma for central electron heating. The present short‐pulse 285/300 antenna array would need to be replaced wi

The processing of materials using rf and/or microwave power is a broad area that has grown significantly in the past few years. We have applied rf and microwave technology in the areas of ceramic sintering, plasma processing, and waste processing. Th

The folded waveguide (FWG) has been tested to the megawatt level in RFTF and shows great promise for tokamak use. It has three primary advantages: low electric field (anywhere) per unit power coupled to the plasma, strong structural capabilities, and

Two new concepts are being developed as possible upgrades to the folded waveguide launcher. The folded stripline is a folded waveguide with an additional conductor positioned inside. The term stripline refers to the resemblance of the design to micro
