Abstract
A system for creating various types of magnetic perturbations relevant to research on mitigation and control of magnetic islands has been developed for the STOR-M tokamak. It utilizes an H-bridge topology and digital controls to switch the discharge from a 51.8 mF capacitor bank and drive current in either a helical coil or a set of discrete coils. This system is capable of safely driving direct or slowly alternating coil currents (< 3 kHz) up to a maximum of 2200 A. At the maximum alternating current frequency of 25 kHz, the highest possible coil current is 1500 A. Preliminary tests have demonstrated modulation of magnetic island rotational frequency during direct current pulses.
