在Heliotron J中研究了氢同位素（氢和氘）在电子回旋共振加热等离子体中的影响。为了分别评估粒子扩散率和对流速度，进行了密度调制实验。应用不同的调制频率（50、100和125 Hz）以确认结果。一个较小的扩散系数和一个较低的向内指向的对流速度在50 Hz调制氘为主的等离子体比在氢为主的等离子体，而没有发现明显的差异在100和125 Hz。估计值的差异可能是由于每个频率处的不同空间响应。结果表明，在Heliotron J中存在着粒子约束的同位素效应。
The effects of hydrogen isotopes (hydrogen and deuterium) were investigated in electron-cyclotron-resonance-heated plasma in the Heliotron J. In order to evaluate particle diffusivity and convection velocity separately, density modulation experiments were performed. Different modulation frequencies (50, 100, and 125 Hz) were applied in order to confirm the results. A smaller diffusion coefficient and a lower inwardly directed convection velocity were obtained at 50 Hz modulation in deuterium-dominant plasma than in hydrogen-dominant plasma, while clear differences were not found at 100 and 125 Hz. The difference in the estimated values is likely to be due to a different spatial response at each frequency. The results suggest that an isotope effect on particle confinement exists in Heliotron J.
