The method of UHF reflectometry for investigation of plasma fluctuations in the torsatron Uragan-3M

Plasma density fluctuations, n/spl tilde//sub e/, play an important role in the energy balance, particle and heat transport, and, in the long run, in the confinement of a thermonuclear plasma. In this paper we present the experimental results on study of the spatial structure of n/spl tilde//sub e/, in the plasma confinement region of the l=3 torsatron Uragan-3M. These data were obtained by means of a multi-channel UHF reflectometry with the homodyne detection.
