Experiment of stability operation region and MHD instability observation on HT-7
Description
Experiments about stability operation region (SOR) on HT-7 and high plasma parameters in Ohmic discharge are performed. Two boundaries of low density limit and Murakami density limit are scanned out through about 80 shots. The Murakami limit Mmax=2.96x1019 m-2/T and Hugill number H=9.5x1019 m-2/T are obtained. On the Murakami boundary, the radiation characters are specially analyzed. Coupling of m=1 and m=2 modes leads impurities from boundary to core, then line radiation of those impurities causes energy quenching inside and near q=1 surface and finally disruption occurs. This kind of disruption restricts Murakami density limit. (author)
