This results in a rippled toroidal field structure, and consequent distortions in fast ion orbits with potentially rapid loss of the affected ions. The ripple loss is an important issue for the design of future tokamak reactors such as ITER because it results in reduced alpha heating as well as potentially severe localized wallreactors.展开更多

In order to sustain the RS operation towards steady-state, off-axis current drive with lowerhybrid (LH) wave at 2.45 GHz is used to control the current profile.展开更多
