HSX是一种准螺旋对称（QHS）仿星器，目前正在威斯康星大学麦迪逊分校Torsatron-Stellarator实验室建造。该装置在其磁性设计方面是独特的，因为磁场谱仅具有单个主导（螺旋）分量。这种设计避免了与传统仿星器相关的大的直接轨道损失和低碰撞性新古典损失。约束磁场对称性的恢复使得该装置中的新经典约束类似于轴对称q=1/3托卡马克。HSX设备的设计具有一套明确的主要物理目标：论证了构造QHS装置的可行性，研究了注入离子的单粒子约束与磁场对称性破缺的关系，比较了螺旋对称系统与轴对称托卡马克和传统仿星器的密度和温度分布，研究对称与非对称仿星器系统中与L-H跃迁有关的电场和边缘偏置等离子体旋转，研究QHS对1/v区电子约束的影响，并研究如何大大减少新古典电子热导率相比，实验{chi}{sub e}的配置文件。参考文献3篇，图4，1个选项卡。
HSX is a quasi-helically symmetric (QHS) stellarator currently under construction at the Torsatron-Stellarator Laboratory of the University of Wisconsin-Madison. This device is unique in its magnetic design in that the magnetic field spectrum possesses only a single dominant (helical) component. This design avoids the large direct orbit losses and the low-collisionality neoclassical losses associated with conventional stellarators. The restoration of symmetry to the confining magnetic field makes the neoclassical confinement in this device analogous to an axisymmetric q=1/3 tokamak. The HSX device has been designed with a clear set of primary physics goals: demonstrate the feasibility of construction of a QHS device, examine single particle confinement of injected ions with regard to magnetic field symmetry breaking, compare density and temperature profiles in this helically symmetric system to those for axisymmetric tokamaks and conventional stellarators, examine electric fields and plasma rotation with edge biasing in relation to L-H transitions in symmetric versus non-symmetric stellarator systems, investigate QHS effects on 1/v regime electron confinement, and examine how greatly-reduced neoclassical electron thermal conductivity compares to the experimental {chi}{sub e} profile. 3 refs., 4 figs., 1 tab.
