本文描述了在Heliotron E的束流加热无电流等离子体中首次测量β和抗磁性。这些测量是用抗磁线圈进行的（1984-1985）。推断的体积平均β显示出良好的协议与动力学β确定的汤姆逊散射电子温度和密度和离子温度分布。在0.94T、3.6MW的中性束注入加热条件下，获得了体积平均β = 0.7-0.9%的γ βτ α DIA。观测到的最大抗磁性β接近并略低于理论MHD预测的值。反磁β和观测到的MHD波动之间的相关性进行了讨论。本文介绍了一种分析螺旋管装置中等离子体抗磁性的一般方法。
The paper describes the first measurements of beta and diamagnetism in beam heated current-less plasmas of Heliotron E. These measurements were performed with a diamagnetic coil (1984–1985). The inferred volume average beta shows good agreement with the kinetic beta determined from the Thomson scattering electron temperature and density and the ion temperature profiles. A volume average beta of ⟨βτ⟩DIA = 0.7–0.9% is obtained with 3.6 MW of neutral beam injection heating at 0.94 T. The observed maximum diamagnetic beta is close to and slightly below the value predicted by theoretical MHD predictions. The correlation between the diamagnetic beta and observed MHD fluctuations is discussed. The paper includes a general technique used to analyse the diamagnetism of the plasma confined in a helical heliotron device.
