提出了一种求解二维场反位形（FRC）平衡问题的新工具（GSEQ-FRC），该工具分别基于固定边界和自由边界条件，包括外加线圈。GSEQ-FRC受益于双参数修正刚性转子（MRR）径向平衡模型和[Ma et al，Nucl. Fusion，61，036046，2021]提出的数值方法，用于定量研究FRC的平衡特性，并将用于快速FRC平衡重建。在GSEQ-FRC中，FRC平衡可以方便地由两个参数确定，即，在分界面$β_s$处的热压和磁压之间的比率，以及层（SOL）的归一化刮擦宽度$δ_s$。固定和自由边界条件下的例子来证明GSEQ-FRC的平衡计算的能力。利用该工具定量研究了影响FRC分界线形状的因素，揭示了FRC从跑道状到椭圆状的变化规律。
英文摘要：
A new tool (GSEQ-FRC) for solving two-dimensional (2D) equilibrium of field-reversed configuration (FRC) based on fixed boundary and free boundary conditions with external coils included is developed. Benefiting from the two-parameter modified rigid rotor (MRR) radial equilibrium model and the numerical approaches presented by [Ma et al, Nucl. Fusion, 61, 036046, 2021], GSEQ-FRC are used to study the equilibrium properties of FRC quantitatively and will be used for fast FRC equilibrium reconstruction. In GSEQ-FRC, the FRC equilibrium can be conveniently determined by two parameters, i.e., the ratio between thermal pressure and magnetic pressure at the seperatrix $β_s$, and the normalized scrape of layer (SOL) width $δ_s$. Examples with fixed and free boundary conditions are given to demonstrate the capability of GSEQ-FRC in the equilibrium calculations. This new tool is used to quantitatively study the factors affecting the shape of the FRC separatrix, revealing how the FRC changes from racetrack-like to ellipse-like.
