In both operations of the Tokamak and the stallarator, ion heating efficiency of bar n (e) delta T (i)/p (net) = 1.2 x 10 to the 13th power eV x 1/kW/cu cm is observed at a power level of 160 kW to 180 kW. The ion absorption efficiency of RF power in the stallarator is two thirds as large as that in the Tokamak. It is confirmed that the perpendicular energetic ion tails are produced near the plasma center and suffered from the pitch angle scattering to the parallel direction, and at the same time, energetic ions escape out of the plasma due to delta B drift. 收起
