| Research Abstract |
The closed helical divertor (CHD) which was based on the outstanding results of the local island divertor (LID) has been developed to be applied to the steady-state operation. The installation of CHD to the Large Helical Device has been performed step by step. In the initial experiment, the sufficient neutral gas compression, as expected in the numerical simulation, was observed in CHD. In addition, it was demonstrated that the edge energy and particle transport can be controlled by changing the edge magnetic ergodicity with resonant magnetic perturbations applied with LID coils.
