New Classes of Quasi-helically Symmetric Stellarators

[摘要] New classes of quasi-helically symmetric stellarators with aspect ratios ??�� 10 have been found which are stable to the perturbation of magnetohydrodynamic modes at plasma pressures of practical interest. These configurations have large rotational transform and good quality of flux surfaces. Characteristics of some selected examples are discussed in detail. The feasibility of using modular coils for these stellarators has been investigated. It is shown that practical designs for modular coils can be achieved.
