Spectroscopic measurements of plasma rotation with parametric abel inversion in the GAMMA10 tandem mirror

摘要

The rotation of cylindrical plasmas has been investigated visible spectroscopy. The rotations of variously charged impurity ions have been measured. Since the detected signal is The line integrated emission, the measurement technique of plasma rotation and the parametric Abel Inversion technique have been developed to obtain the local impurity emission profile and the potential Profile. Three different types of fitting functions for the parametric Abel inversion technique have been Examined using numerical simulations.
