摘要：

The gyrotron for an Electron Cyclotron (EC) system has been developed for the purpose of driving current and heating plasma in experimental fusion machines. A gyrotron requires accurate magnetic field distribution for the resonant interaction between the electron beam and radio frequency (RF) wave energy. A superconducting magnet system was designed and fabricated for a 1 MW gyrotron in a frequency range of 110-140 GHz. The system consists of super conducting magnets, a cryostat, a two stage cooler and power supplies. The diameter of the gyrotron bore is 220 mm. A magnetic field of 5.0 T in the resonance region was obtained with a 340 mm bore superconducting split coil. A magnetic field of 0.25 T in the gun region was obtained with two solenoid coils. A persistent current switch (PCS), removable current leads and two stage cooler were adopted in order to decrease the heat load of liquid helium. The superconducting magnet system has successfully achieved a 110% rated current without quenching.
