[en] The design parameter, electromagnetic and water-cooling analysis and fabrication process of EAST active feedback control coils are presented. As the diagonal leaders suffer huge vertical force variation, conventional organic insulating material cannot meet the requirements. Magnesium oxide was used as insulating material and supports were added to both ends of the diagonal leaders. Water-cooling calculations show that the temperature of the copper conductor and water is linearly related to the distance from the point to the water inlet. In order to assure the temperature of outlet water not be heated to boil, the relation of the minimum velocity of water and operation ratio is about v ≈ 6 K when the current in the coil is 20 kA.
