Abstract

The design process regarding ferritic insertion in the JT-60U is described from the viewpoint of the behavior of energetic ions. The confinement of energetic ions and the absence of unfavorable heat flux on the first wall were assessed using the Fully Three-Dimensional magnetic field OFMC code, which was developed for the toroidal field ripple reduction experiment program utilizing ferritic inserts in the JFT-2M. In the final design, the absorbed power in the neutral beam injection is improved by a factor of about 1.3 in a large volume plasma with Bt0 = 1.9 T.
