Abstract Text:
The proposed scheme uses centrifugal confinement of the target
plasma in a MIF scheme. The rotating mirror target has good stability and confinement, and the effect of velocity shear in suppressing instabilities should help to form a good contact surface between target and driver, as well as delaying the onset of
Rayleigh-Taylor instabilities. The supersonic rotation of the
target provides an additional degree of freedom in which energy can
be stored, transforming into thermal energy by viscous losses
during the late stages of the implosion. During the compression
phase the diamagnetic current and the FxB current due to
centrifugal force combine to cause field reversal, leading to an
FRC configuration in the final stages of compression. The
formation of an FRC improves the confinement and causes the
compression to scale faster than 1/r^2[1]. In addition, the
cylindrical geometry permits use of a modified Z-pinch driver,
eliminating some of the problems with blow-by that plague coaxial
plasma guns. The due to the cylindrical geometry the magnet design
is simple, and the reactor can be scaled in a simple manner by
increasing its length.
