Title:

Some Features of Particle Orbit Behavior in LHD Configurations

Date of publication:

Mar. 1993

Key words:

helically trapped particles, radial electric field, heliotron/torsatron, ion orbit loss

Abstract:

Localizations of helically trapped particle losses on the last closed magnetic surface in different LHD configurations are studied. The effects of electric field, finite beta and bootstrap current are taken into account. It is shown that the angular location of the helically trapped particle losses may be controlled by the change of vertical field coil currents.
