K. Yatsu et al., MAGNETIC-FIELD CONFIGURATION FOR TANDEM MIRROR WITH AXIALLY DISTRIBUTED MULTIPOLE FIELD, Plasma physics reports, 23(9), 1997, pp. 774-777
A magnetic field configuration for a tandem mirror is proposed in whic
h weak multipole fields are applied to all minor cells of a tandem min
or. The MHD stability criterion of the magnetic field is studied. An M
HD stable configuration is not yet obtained but hopefully will be obta
ined by further study.
