这是一份关于在 CHS 中使用双重离子束探头进行波动测量的报告。观察结果表明，在电子回旋加速器加热的等离子体中，数十种具有间歇性的相干模式共存。发现这些模式在环形方向上具有长距离相关性。模式的径向结构是通过电位波动来评估的。其特征与测地线声学模式的特征一致。
This is a report on fluctuation measurements using twin heavy ion beam probes in CHS. The observation shows that dozens of coherent modes with intermittent nature co-exist in an electron cyclotron heated plasma. The modes are found to have a long-distance correlation in the toroidal direction. The radial structure of the modes is evaluated in potential fluctuation. The characteristics are consistent with those of the geodesic acoustic modes.
