Abstract

The complete superconducting toroidal ﬁeld (TF) magnet of the JT-60SA tokamak (R=3 m, a=1.2 m) was ﬁrst energized in February 2021 and reached its full design ﬁeld (2.25 T on-axis) on 02 March. Tokamak operation was interrupted due to an arc on the largest poloidal ﬁeld coil EF1 but restarted in 2023 following extensive improvements. In 2023 the TF magnet was used frequently during August – December, during commissioning of the magnet system, plasma operations and in support of electron cyclotron wall cleaning (ECWC).
