Parameter for the vertical-position control of dee-shaped plasmas in Doublet III
Technical Report
·
OSTI ID:6449080
A simple method has been developed using three magnetic probes to detect the vertical position of the center of dee-shaped plasmas located in the upper lobe of Doublet III. This parameter has no dependence on the plasma current and only a small dependence on the horizontal (radial) position of the plasma column. The comparison between the new parameter and the result of MHD calculation shows good correlation with the vertical position of the plasma center. This provides an effective means for improving control of the plasma position and maintaining stable dee plasmas.
