Overview of Power Supplies for JT-60SA Superconducting Magnets

Abstract

The superconducting Satellite Tokamak machine, “JT-60SA,” under construction at the National Institutes for Quantum and Radiological Science and Technology (QST) is an international collaborative project between Japan and Europe. It consists of superconducting toroidal and poloidal field coils, and some normal conductive in-vessel coils. This commentary describes the key features of the overall circuit configuration and the expected performance of each component of the power supply system for the superconducting magnets in JT-60SA.
