无电流等离子体的辐射（RF）加热在基本电子回旋频率下进行。吸收功率分布是根据RF脉冲关闭后电子内部能量分布的衰减来确定的。在回旋共振层的各个位置处的吸收功率分布的测量值与由射线跟踪代码预测的单程吸收分布进行比较。研究了电子温度、密度和离子温度随吸收功率、径向分布和电子线平均密度的变化规律。最后，通过回归分析得到的能量约束时间的缩放进行了比较与中性束加热等离子体的缩放。
Radiofrequency (RF) heating of currentless plasmas is performed at the fundamental electron cyclotron frequency. The absorbed power profile is determined from the decay of the electron internal energy profile immediately after the RF pulse is turned off. Measurements of the absorbed power profile at various positions of the cyclotron resonance layer are compared with single-pass absorption profiles predicted by a ray tracing code. The profiles of electron temperature, density and ion temperature are studied as a function of the absorbed power, its radial profile and the electron line averaged density. Finally, a scaling of the energy confinement time obtained by regression analysis is compared with a scaling for neutral beam heated plasmas.
