在利用鞍形环检测锁模时，如何去除由鞍形环拾取的轴对称平衡通量是一个有待解决的问题。当马鞍环附近有导电结构时，问题变得更加困难。在本文中，我们提出了一个基于集总涡流电路的解析模型，并用它来解释测量的平衡磁通和相应的涡流磁通。利用该模型，对联合德克萨斯实验托卡马克的鞍形回路实现了水平场线圈和环形场线圈诱导磁通的精确补偿，相对误差小于1%。本文还提出了一种补偿锁模检测器检测平衡磁通的新方法。
In the detection of locked modes using saddle loops, the problem of how to remove the axisymmetric equilibrium flux picked up by the loops has still to be solved. The problem becomes more difficult when there are conductive structures located near the saddle loops. In this paper, we present an analytical model based on lumped eddy current circuits and use it to interpret the measured equilibrium flux and the corresponding eddy current fluxes. Using this model, precise compensation for fluxes induced by the horizontal field coils and the toroidal field coils, with relative errors of less than 1%, has been realized for the saddle loops in the Joint Texas Experimental Tokamak. This paper also presents a new method to compensate for the detection of equilibrium flux by the locked mode detector.
