A new scheme to achieve controlled thermonuclear fusion, based upon the hybrid concept of the Z-{Theta} pinch, is described. In this scheme fusion conditions may be achieved by placing a small diameter fiber or straw coaxial with an annular gas puff Z-pinch and axial magnetic field. The imploding annular Z-pinch entrains the axial field compressing it rapidly to megagauss values. This induces an azimuthal {theta} pinch current on the fiber surface with a rise time at least an order of magnitude faster than the Z-current rise time. The ultrahigh magnetic field traps fusion alpha particles and the sheared magnetic field is more stable than linear pinch configurations. Preliminary experimental data, obtained using the UCI Z-pinch facility, confirm the qualitative features of this concept including the generation of the fiber plasma and improved stability. We have modeled this coupled Z-{Theta} pinch system, including major heating and energy loss mechanisms, and developed basic scaling laws for this scheme. This paper summarizes results obtained to date.
