将离子回旋加热应用于大螺旋装置。当质子-回旋加速器共振在磁场强度面鞍点附近时，离子-回旋加速器发生强阻尼。在这些条件下，有效的等离子体加热时间超过一分钟。观察到一个高能离子尾巴，有效尾巴温度由波加速度和电子拖弛豫之间的平衡决定。在0.8 ~ 1.3x10(19) m（-3）的密度范围内，没有明显的粒子轨道损失效应。
Ion-cyclotron heating was applied to the Large Helical Device. When the proton-cyclotron resonance was near the saddle point of the magnetic field-strength plane, strong ion-cyclotron damping occurred. Under these conditions efficient plasma heating was achieved for more than one minute. A high-energy ion tail was observed, and the effective tail temperature was determined by a balance between the wave acceleration and the electron-drag relaxation. There was no apparent sign of particle orbit loss effect in the investigated density range of 0.8-1.3x10(19) m(-3).
