Abstract

We describe a high-k mm-wave scattering diagnostic for measuring binormal wavenumber electron scale turbulence on the MAST-U spherical tokamak. Gaussian wave optics and beam-tracing calculations are presented that show the predicted spatial and wavenumber resolution of the diagnostic along with the sensitivity of measurement. The proposed system will operate at a frequency of 376GHz and will facilitate adjustable localization of the turbulence measurement from the magnetic axis out to the plasma edge.
