It consists of supercon- ducting poloidal field (PF) magnet system, toroidal field (TF) magnet system, vacuum vessel with inner parts, ther- mal shields and cryostat vessel. The mission of the project is to widely investigate both physics and technologies of advanced tokamak operations, especially the mechanism of power and particle handling for steady-state operations. The cryogenic component is mainly composed of superconducting TF and superconducting PF coils that ensure the ability of sustaining magnetic field for plasma confinement, control and shaping in steady-state.

文摘EAST is a full superconducting tokamak with an elongated plasma cross-section. It consists of supercon- ducting poloidal field (PF) magnet system, toroidal field (TF) magnet system, vacuum vessel with inner parts, ther- mal shields and cryostat vessel. The mission of the project is to widely investigate both physics and technologies of advanced tokamak operations, especially the mechanism of power and particle handling for steady-state operations. The cryogenic component is mainly composed of superconducting TF and superconducting PF coils that ensure the ability of sustaining magnetic field for plasma confinement, control and shaping in steady-state.
