Abstract

EAST (Experimental Advanced Superconducting Tokamak), a National Mage-project of Science Research of China, is a very important fusion experiment facility. The ability of magnetic confinement to plasma can be improved by elongating plasma cross-section to form divertor configuration in EAST. But elongated plasma has vertical displacement instability, without control, plasma will dash against wall of vacuum vessel and disrupt, that will cause failure of plasma discharge. So feedback control system is needed to restrain plasma vertical displacement. Fast control power supply excites active feedback coils, which produces magnetic field to control plasma’s displacement. The validity of proposed scheme was confirmed by experiments, the active feedback system can reach design demand.
