The mission of the low aspect ratio spherical tokamak NSTX-U is to advance the physics basis and technical solutions required for optimizing the configuration of next-step steady-state tokamak fusion devices. NSTX-U will ultimately operate at up to 2

Inversion technique to obtain local ion temperature profiles for an axisymmetric plasma with toroidal and radial velocities

Autor: Ronald E. Bell

Publikováno v: Plasma Physics and Controlled Fusion. 63:045023

A matrix inversion technique is derived to calculate local ion temperature from line-integrated measurements of an extended emission source in an axisymmetric plasma which exactly corrects for both toroidal velocity and radial velocity components. Lo
