Study of Low-Frequency Microturbulence in the Microtor Tokamak by Far-Infrared Laser Scattering
Abstract
The first far-infrared laser scattering measurements from a tokamak plasma are reported. Spatially and temporally resolved power spectra of density fluctuations in the Microtor plasma have been studied with an absolutely calibrated far-infrared scattering system which allowed measurement of the wide range of wave numbers from k=3 to 50 cm-1. The wave-number dependence of the scattered power of 0.6<~k⊥ρi<~2 was found to satisfy a k-3.5 form.
