Description

A 119 μm laser scattering experiment is used on ASDEX to investigate wavenumber and frequency spectra of the density fluctuations occurring in the different operational modes of the machine. The aim of the measurements is to get insight in the physical nature of the fluctuations and their possible role in connection with anomalous transport. Since no complete theory exists, the simple guidelines of gyroradius-scaling and mixinglength level are used in the choice of parameters to be varied. Particular emphasis has been placed on the investigation of the fluctuations in the ohmic phase. (orig./AH)
