Abstract:
A real-time motional Stark effect diagnostic has been developed and deployed on the Korean Superconducting Tokamak Advanced Research (KSTAR). The diagnostic receives data from 25 spatial channels with analysis from either the standard motional Stark effect (MSE) system or the MSE with the background polychromator system on KSTAR. The system streams tan(γmag) (the tangent of the magnetic field pitch angle) to the real-time plasma control system with ∼10 ms time resolution for use in real-time control and equilibrium reconstruction. Here, we present initial results from the real-time system operation during the most recent experimental campaign, comparison with offline analysis, and information regarding the conditions for best MSE data on KSTAR. Real-time background subtraction will be developed during the upcoming KSTAR wall upgrade and is expected to be available in the post-upgrade run campaigns.
