Description

In JF2M, the characteristics of the high confinement mode (H-mode) have been studied in the various plasma conditions. The results of these studies indicate that the quiescent H-mode (H-mode without ELM's) phase was terminated by the large increment of radiation losses during the quiescent H-mode phase. Thus, it appears that the impurity problem is one of the most serious problems to obtain the longer duration of the quiescent H-mode phase. In this paper we present the experimental results concerned with the impurity behavior during the quiescent H-mode phase by using spectroscopic method in JFT-2M. (author) 2 refs., 5 figs
