The final plasma pressure of the [theta]-pinch exceeds the magnetic pressure so that the [theta]-pinch then expands-the only confinement is inertial. Magnetic confinement involving pressure balance equilbirium for a sufficient time to achieve breakeven with deuterium/tritium is not possible within the limits of present pulse-power technology, whereas with inertial confinement only, our calculations indicate that breakeven can be exceeded with the present state of the art. If the preheat due to Ohmic heating can be eliminated, for example by seeing with high Z impurities to achieve radiative cooling, an energy-gain factor of 8 is predicted. For ion acceleration an ion beam is injected and trapped inside this rising magnetic field. Due to the conservation of canonical-angular momentum the ions are accelerated to a final azimuthal energy a hundred momentum to a thousand time greater than their initial energy ([ital E][theta][sub final]=10's of MeV/amu). Such high energy ion beam could be used to produce intense X-ray radiation. [copyright]American Institute of Physics
