【Abstract】 Traditional electron cyclotron resonance( ECR) ion source coil with higher power density have some disadvantages,such as high pressure in the water-cooling system,restricted cooling ability,complex maintenance and operation system. A new ECR ion source coil was designed by using self-circulation evaporative cooling technology. The new design is based on the principle of self-circulation evaporative cooling,besides,the layout structure of ECR ion source coil and high operation reliability are both considered. The coil is composed by disk coil arrays. Vertical cooling channels are set among unit coils,where evaporative cooling coolant flows automatically driven by the heat of coils. According to the parameter index of LECR — DRAGON ion source magnet coil,the test model of evaporative cooling magnet coil was built. The experimental results show that the window current density of the new designed coil can be 12 A / mm~2,which can maintain a long-term stable and reliable running. The evaporative cooling magnet coil can meet the requirements of practical engineering.更多还原
