摘要
天环一号(CAT-1)是国内首个采用磁悬浮偶极场磁体设计的磁约束等离子体装置.根据CAT-1装置总体目标和参数设计要求,采用线电流简化模型,基于矢量磁场、力学平衡及动力学等方法,对悬浮磁体稳定性进行了分析计算,给出了装置悬浮磁体、托举线圈和状态调节线圈的总体尺寸、空间位置与布局、电流、重量、特征稳定性能及作用关系等设计参数.结果表明:对于CAT-1装置的悬浮磁体1 200 kg、电流5 MA、悬浮距离2.0 m设计目标,托举线圈半径最优值为1.7 m,相应的电流为3.49 kA,为实现对悬浮磁体偏移运动的有效阻减及控制,平衡点附近工作区域应限制在|Δz|＜100 mm、|Δer|＜50 mm、|Δα|＜π/24.
Abstract
The Tianhuan One is the first magnetically-confined plasma device in China using a magnetically floating dipole field magnet.According to the overall objectives and design requirements of the CAT-1(China Astro Torus-1)device,a sim-plified linear current model was used to analyze and calculate the stability of the floating magnet based on methods such as vector magnetic field,mechanical balance and dynamics.The design parameters of the floating magnet,levitation coil,and Tilt-Slider-Rotation coil in the device were given,including the overall size,spatial position and layout,current,weight,characteristic stability performance and their relationship.The results show that the optimal value of the levitation coil radius is 1.7 m and the corresponding current is 3.49 kA for the design goals of the floating magnet with the weight of 1 200 kg,current of 5 MA and sus-pension height of 2.0 m.In order to achieve effective resistance and control of the floating magnet offset movement,the working area near the balance point should be limited to|Δz|＜100 mm,|Δer|＜50 mm and|Δα|＜π/24.
