Abstract
A method to obtain electron density profiles from chordal interferometric measurements of a tokamak plasma has been extended to the non-axisymmetric stellarator geometry of the Advanced Toroidal Facility (ATF) torsatron. The method requires a known magnetic flux surface geometry expressed in spectral form. The method has been applied to both interferometer density data and bolometer irradiance data from ATF, and results are presented. The resulting inverted density profiles are integrated along a horizontal path and compare favorably with line integral measurements of the density. Sensitivities of the resulting profiles to variations in the flux surface geometry and errors in the measurements are discussed.
