Application of function parametrization for plasma position estimation in Aditya-U tokamak
The fast and accurate measurement of plasma position for the tokamak control system is determined by the application of function parametrization on the magnetic probe data. In Aditya-U tokamak, a poloidal array of 16 probes is installed around the plasma column, and the plasma position has been estimated by an algorithm based on the function parametrization technique. The validation of the method is done by placing a current loop inside the vacuum vessel at different positions. It is found that the measurement accuracy improved as the number of probes was increased from 7 to 16. Also, to enable the real-time position measurement in the future, time integration of the probe output is enabled using the integrator circuits in 7 probes, which will be extended to all the probes.
