The fully superconducting tokamak JT-60SA achieved its first plasma already during the first operational campaign (OP-1) in 2023. To obtain this result, a suitable operation procedure of magnet system, temperature and coil current control was essential. During the same operational campaign, OP-1, JT–60SA was able to generate a diverted plasma with 1.2 MA of plasma current. However, the PF coil current was limited to 5 kA during this operational campaign with respect to a maximum current up to 10 kA tested during the single coil excitation test performed before the plasma experiments. In the next operational campaign OP-2, nominal current (20 kA) operation will be demonstrated for the PF coil system, so they can fulfill their purpose of producing high-performance plasmas. Aiming at this, various improvements were considered for safe energization and protection of the coils.
