Asymmetric Mirror Confinement

Mirror machines are generally symmetric both azimuthally and axially. However, an axial asymmetry can be introduced either through asymmetric mirror ratios at the opposite ends or in the shape of the strength of the axial magnetic field even at the same mirror ratio. In either case, there is the opportunity for selective detrapping at one end or the other. A potential application of asymmetrical mirror particle transport is the generation of a toroidal current in a bumpy torus.
