摘　　要：根据热核聚变用140GHz回旋振荡管技术要求,研制了一套最高磁场可达6T的无液氦超导磁体。针对回旋振荡管的特殊的磁场位型要求,设计了一套由八组线圈组成的低温超导磁体,工作电流102A,工作磁场6T,不均匀度±1.4‰。采用单台1.5 W@4.2K的G-M制冷机做为冷源,经过70h,将超导磁体冷却至3.6K,并成功加电运行。140GHz回旋振荡管用低温超导磁体的研制成功,为热核聚变用140GHz回旋振荡管的研究打下了技术基础。According to technical requirement of the 140 GHz gyrotron oscillator for thermonuclear fusion,a set of no-helium superconducting magnet with high magnetic field up to 6T was developed.For special magnetic field requirements of gyrotron oscillator,the low temperature superconducting magnet is consisted of eight groups coil with working current of 102 A,magnetic field up to 6T,uneven degrees of±1.4‰.Using single 1.5 W@4.2K G-M refrigerator as cold source,the superconducting magnet was cooled to 3.6Kafter 70 h,and the power was operated successful.Development of low temperature superconducting magnet lays technical foundation of 140 GHz gyclotron oscillators for thermonuclear fusion.
