高次谐波快波（HHFW）加热已被提出作为一个特别有吸引力的手段，用于等离子体加热和电流驱动的高β等离子体中，可以实现在球形环（ST）设备。国家球形环实验（NSTX）[M. Ono，S. M. Kaye，S. Neumeyer等人，在Proceedings of the 18 th IEEE/NPSS Symposium on Fusion Engineering，阿尔伯克基，1999（IEEE，皮斯卡特维，NJ，1999），p.53）中描述的装置就是这样一种装置。在NSTX上安装了一个射频加热系统，以探索HHFW加热的物理特性，通过射频波进行电流驱动，并用作展示ST概念作为聚变装置的吸引力的工具。到目前为止，实验已经证明了许多理论预测的HHFW。特别是，在广泛的等离子体参数和波平行相速度，波加速的高能离子，和指示电流驱动定向波谱的电子上的强波吸收已被观察到。此外，HHFW加热还用于...
High harmonic fast wave (HHFW) heating has been proposed as a particularly attractive means for plasma heating and current drive in the high beta plasmas that are achievable in spherical torus (ST) devices. The National Spherical Torus Experiment (NSTX) [M. Ono, S. M. Kaye, S. Neumeyer et al., in Proceedings of the 18th IEEE/NPSS Symposium on Fusion Engineering, Albuquerque, 1999 (IEEE, Piscataway, NJ, 1999), p. 53] is such a device. An rf heating system has been installed on the NSTX to explore the physics of HHFW heating, current drive via rf waves and for use as a tool to demonstrate the attractiveness of the ST concept as a fusion device. To date, experiments have demonstrated many of the theoretical predictions for HHFW. In particular, strong wave absorption on electrons over a wide range of plasma parameters and wave parallel phase velocities, wave acceleration of energetic ions, and indications of current drive for directed wave spectra have been observed. In addition HHFW heating has been used to ...
