Comparison of transient electron heat transport in LHD helical and JT-60U tokamak plasmas
Description
Full text: Transient transport experiments are performed in plasmas with and without Internal Transport Barrier (ITB) on LHD and JT-60U. In the no-ITB plasmas, two different types of non-linearity of the electron heat transport are observed from cold pulse propagation. The heat diffusivity depends weakly on both of electron temperature and temperature-gradient in LHD, while the heat diffusivity depends strongly on the temperature-gradient in JT-60U. In the ITB plasmas, a cold pulse growing driven by the negative temperature dependence of heat diffusivity is commonly observed both in LHD and JT-60U. (author)
