title: Inversion technique to obtain local rotation velocity and ion temperature from line-integrated measurements for elongated tokamak plasma.
abstract: An inversion technique is presented to calculate local toroidal and poloidal rotation velocity and ion temperature from line-integrated measurements of impurity lines by a matrix method. The effects of the rotation velocity on the ion temperature are analyzed in particular. An accurate inversion formula for the ion temperature is obtained. Several experimental geometries or configurations of line-integrated diagnostics in tokamaks are presented. For a plasma that is up-down symmetric, both the toroidal rotation velocity and poloidal rotation velocity can be deduced from one special line-integrated measurement.
