一、引 言 在一些较大型的托卡马克装置上的研究业已表明,应用外激发离子伯恩斯坦波(IBW)对托卡马克等离子体进行辅助加热是一种极具有竞争力的方法。然而,对在托卡马克位形的等离于体中,IBW的激发、传播等一些基本过程,仍需做进一步的实验研究。我们利用小型装置的低温、低密度特点,采用高空间分辨的射频(RF)电探针作为IBW的主要探测 I. INTRODUCTION Studies in some of the larger tokamak devices have shown that it is a very competitive method to apply auxiliary heating of tokamak plasma using the out-excited ion Bernstein wave (IBW). However, some basic processes such as excitation and propagation of IBW in the tokamak shape are still subject to further experimental study. We use low-temperature, low-density features of small devices, using high-spatial resolution radio frequency (RF) probes as the primary detection of IBW
