  A new linked mirror device for magnetic confinement experiment is proposed.
The new linked mirror device consists of two straight magnetic mirrors
connected by two half-torus. The structure of the configuration as a whole is
three dimensional because the two linear mirror sections are not parallel. The
angle between the two mirror sections generates rotational transform which
results in good magnetic confinement of toroidally processing passing
particles. In this way the usual loss cone of the traditional linear mirror
machines is eliminated. The single particle confinement is similar to that of
tokamaks with most of particles well confined. The calculated neoclassical
confinement is very good and is even better than that of an equivalent tokamak.
Potentially the proposed linked mirror configuration can allow MHD stable high
beta equilibria with good plasma confinement suitable for neutron sources and
magnetic fusion reactors.
