DOI: 10.7566/jpsj.86.064501
Abstract: 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… read more here.
