In this Letter we report measurements of collective Thomson scattering (CTS) spectra with clear signatures of ion Bernstein waves and ion cyclotron motion in tokamak plasmas. The measured spectra are in accordance with theoretical predictions and show clear sensitivity to variation in the density ratio of the main ion species in the plasma. Measurements with this novel diagnostic demonstrate that CTS can be used as a fuel ion ratio diagnostic in burning fusion plasma devices.
在这封信件中，我们报告了托卡马克等离子体中集体汤姆逊散射（CTS）谱的测量结果，这些结果具有清晰的离子 Bernstein 波和离子回旋运动特征。所测量的谱与理论预测相符，并清楚地显示出对等离子体中主要离子种类密度比变化的敏感性。使用这种新型诊断方法的测量表明，CTS 可以用作燃烧聚变等离子体装置中的燃料离子比诊断。
