Non-thermal electron velocity distribution measured by electron cyclotron emission in Alcator C tokamak

Creators

Description

The non-thermal electron velocity distribution of lower hybrid rf heated plasmas in the Alcator C tokamak is deduced from measurements of electron cyclotron emission using a specialized vertical viewing optics arrangement. At a density of anti n/sub e/ = 0.7 x 1020m-3, the reconstructed distribution function in the range 50keV less than or equal to E less than or equal to 230keV shows enhancement in the parallel direction with a perpendicular spread equivalent to T/sub perpendicular/ approx. = 30keV. The line average energetic electron density in this energy range is approximately 7 x 1015m-3 during the rf. 9 refs., 4 figs
