Abstract

A 200-kW, ∼60-GHz gyrotron will be used on TFTR during D-T operation for collective Thomson scattering diagnostics of confined alpha-particle velocity distribution and density. Scattering angles of up to 120°are under consideration using x-mode propagation to increase the density cutoff limit. Useful signal-to-noise ratios will be possible in plasmas where n_e ≳ 5×10¹³ cm^-3, n_α ≳ 2×10¹¹ cm^-3, and the background emission is ≲ 30 eV equivalent blackbody level.
