In-vessel coils for magnetic error field correction in JT-60SA

Matsunaga, Go; Takechi, Manabu; Sakurai, Shinji; Suzuki, Yasuhiro*; Ide, Shunsuke; Urano, Hajime

JT-60SA is designed and under construction as fully superconducting tokamak under a combined project of the ITER satellite tokamak program of EU-JA (Broader Approach Activities) and the Japanese national program. One of the main purposes of JT-60SA is the steady-state high-beta operation above the ideal no-wall beta limit. To achieve this, we have designed in-vessel coils, thus error filed correction coils (EFCCs) for a correction of magnetic error fields that affect plasma initiation and induce magnetic island locking. We will report the design of the EFCC in JT-60SA from an engineering and a physics points of view.
