在NIFS设计了一种准轴对称结构的低纵横比仿星器CHS-qa，其主要目的是对约束改善进行实验研究。利用HINT代码，不需要假定磁面嵌套，得到了高β平衡。采用SPBSC代码计算带自举电流的平衡态，并采用TERPSICHORE代码评估其全局MHD稳定性。研究了磁场的边界结构，确定了分流剂的选择范围。提出了一种计算极小非轴对称环面结构新经典输运性质的新方法。提出了结构性质的控制旋钮，用于研究改进约束。
A low aspect ratio stellarator CHS-qa with a quasi-axisymmetric configuration has been designed at NIFS, whose main objective is the experimental study of confinement improvement. The high beta equilibrium was obtained with the HINT code which does not require the assumption of nested magnetic surfaces. The equilibria with bootstrap current were calculated using the SPBSC code and their global MHD stability was evaluated with the TERPSICHORE code. The boundary structure of the magnetic field was examined to scope divertor options. A new method of calculating the neoclassical transport properties was developed for toroidal configurations with very small non-axisymmetry. The control knobs of the configuration properties are proposed for the study of improved confinement.
