Progress of Manufacturing CS and EF Coils for the JT-60SA Tokamak

Manufacturing of the superconducting poloidal field (PF) coils in the JT-60SA tokamak is in progress. Recently, three equilibrium field (EF) coils, i.e., EF4, EF5, and EF6, intended for installation beneath the TF coils, were already completed with precision and temporarily installed on the cryostat base in the torus hall. The remaining three coils, i.e., EF1, EF2, and EF3, are being manufactured. The winding of EF1 and EF2 is completed, and stacking and connecting joints work is progressing. The pancake coil for EF3 coil will be continued to be wound until the end of this year. For the central solenoid (CS), the first module (CS1) is almost completed.
