Research output: Contribution to journalArticlepeer-review


A single-null divertor configuration in the l-2 helical-heliotron/torsatron (l: multipolarity of the field) is studied. The l=1component is introduced by placing two helical windings with a small asymmetry. This can be also realized by imposing the distributed current of coils in the poloidal direction. In this configuration, the connection length of the field line outside of the separatrix becomes longer, and the access of the heating (such as ICRF wave) from the low-field side is possible.
