摘要：

Collective scattering measurements on DIII-D have been complicated by significant toroidal and poloidal plasma rotation which produces large and inhomogeneous radial electrical fields which in turn Doppler shift the spectra of the scattered radiation. From independent measurements of the radical electric field profile, the radial variation of the fluctuation magnitude can be approximated from the frequency spectrum of the scattered radiation so the improved resolution is related to the scale length of the radial electrical field. Such improved spatial resolution will allow the interaction between local gradients and the fluctuation level to be investigated in more detail. © 1995 American Institute of Physics.
