摘　　要：电子真空回旋器件是一种对磁场精度要求较高的微波源装置,一般采用超导磁体提供磁场环境.超导磁体的应用中,磁场分布的实现是超导磁体设计的核心问题.提供回旋器件磁场的高温超导磁体包含较复杂的磁体绕组,为了解决此类设计计算问题,本文提出了一种包含设计区域约束的线性优化方法进行回旋器件高温超导绕组的设计优化,通过分步的约束和线性优化计算,可得到同时满足设计要求和绕组可实现的设计磁场电流分布设计.计算实例的结果给出了一个提供磁场强度1.3 Tesla,长度285 mm的均匀磁场区域,同时满足多位置的磁场要求,设计结果与要求一致度较好,精度满足应用需求.该计算方法是一种可适用于较复杂磁场要求和超导绕组结构的设计优化方法.Gyrotron is a kind of millimeter-wave source device which requires precise high field that usually generated by superconducting magnet.Here,we concern about winding design of High-temperature superconducting magnets which constructed by double-pancakes,appeared more complex when providing precise magneticfield.In order to solve the problem of this kind,this paper proposes a linear programing optimization method with constrained values for the HTS winding design.By imposing constraints on values by steps,optimization result can be obtained which meet both the winding requirements and the current distribution in conductor.The result of the programing example needs providing a uniform magnetic field region with magnetic field strength of 1.3 Tesla and length of 285 mm,and also specific multiple positions at the same time.The design results arein goodagreement withtherequirements,andalsotheaccuracy.This designoptimization methodcan be appliedto complex magnetic field requirements and superconducting winding structure as well.
