A 4 T Superconducting Magnet for Gyrotron With Homogenous Regions of 150 and 250 mm.

The development of a high frequency, high harmonic gyrotron based on a superconducting magnet is described. A conduction-cooled superconducting magnet with the warm room of Φ 80 mm and the center field of 4 T was designed and fabricated. The superconducting magnet has two homogenous regions with length of 150 mm and 250 ram. The homogeneity of magnetic field is about ±0.25%. All the homogeneous regions are with the same starting point and the field is decayed to 1/6–1/7 from the front point of the homogeneous region to 195 mm. This paper describes the design and fabrication of the superconducting magnet for Gyrotron. [ABSTRACT FROM AUTHOR]
