Notes:
The numerous applications of cw collective Thomson scattering in fusion plasmas are greatly enhanced by the addition of a multichannel capability. This permits the determination of the dispersive properties (ω vs k) of waves on a single tokamak discharge. This paper describes the development, calibration, and application of such systems in the far-infrared spectral region. The measurement of the wave dispersion of externally excited ion Bernstein waves leads to the determination of ion temperature in a tokamak plasma. In addition, the study of naturally occurring microturbulence has produced a series of unique observations which has both motivated theoretical effort and clarified the role of density fluctuations in anomalous transport.
