Experimental Study of Potential Confinement of ICRF-Heated Plasma in GAMMA 10

概要

論文の詳細を見る
Potential confinement of an ICRF-heated plasma in GAMMA 10 is experimentally studied. The potential confinement was shown from data of one-end plugging and both-end plugging. The waveform of end loss current and an analysis of end loss ion energies have also indicated potential formation and confinement. Central cell line density increases 50% by the potential confinement. Some radial loss was observed and a radial ion-current ratio due to the radial loss was measured by using the data from one-end plugging. The radial ion-current ratio of the shot with an increase in the line density by 50% was estimated to be less than 3%.
