摘要：

A multichannel, heterodyne, far-infrared laser interferometer with high spatial and phase resolution is employed on TEXT to characterize the equilibrium density profile for the full range of TEXT discharge parameters. Gaussian and parabolic functional fits with three free parameters are made to the measured profiles and compared. Scaling of the equilibrium density profile shape with plasma current, toroidal magnetic field, and density is clearly observed. By performing a regression analysis on each free parameter for the functional fit, one can construct a set of analytical relations describing the TEXT density profile for steady-state ohmic discharges. The database used to identify these relations contains 50 different discharge conditions.
