A system and apparatus for controlled fusion in a field reversed configuration (FRC) magnetic topology and conversion of fusion product energies directly to electric power. Preferably, plasma ions are magnetically confined in the FRC while plasma electrons are electrostatically confined in a deep energy well, created by tuning an externally applied magnetic field. In this configuration, ions and electrons may have adequate density and temperature so that upon collisions they are fused together by the nuclear force, thus forming fusion products that emerge in the form of an annular beam. Energy is removed from the fusion product ions as they spiral past electrodes of an inverse cyclotron converter. Advantageously, the fusion fuel plasmas that can be used with the present confinement and energy conversion system include advanced (aneutronic) fuels.

A high performance field reversed configuration (FRC) system includes a central confinement vessel, two diametrically opposed reversed-field-theta-pinch formation sections coupled to the vessel, and two divertor chambers coupled to the formation sections. A magnetic system includes quasi-dc coils axially positioned along the FRC system components, quasi-dc mirror coils between the confinement chamber and the formation sections, and mirror plugs between the formation sections and the divertors. The formation sections include modular pulsed power formation systems enabling static and dynamic formation and acceleration of the FRCs. The FRC system further includes neutral atom beam injectors, pellet or CT injectors, gettering systems, axial plasma guns and flux surface biasing electrodes. The beam injectors are preferably angled toward the midplane of the chamber. In operation, FRC plasma parameters including plasma thermal energy, total particle numbers, radius and trapped magnetic flux, are sustainable at or about a constant value without decay during neutral beam injection.

The invention discloses a magnetized plasma fusion ignition device and an inertial magnetic confinement fusion method. The method comprises a field-reversed configuration (FRC) forming and accelerated transmission system, a merging collision system, and an implosion and compression system. The forming and accelerated transmission system is distributed on two sides symmetrically. The merging collision system is in the middle and comprises a metal sleeve, a coil sleeving the outer side of the metal sleeve, and magnetic mirror coils on two ends. The implosion and compression system comprises the metal sleeve and electrodes, and the electrodes are connected with a pulse driving power source capacitor set. The method comprises the following steps: by means of FRTP technology, initial FRC plasmas are formed and head-to-head collision is induced; in the space, the plasmas are merged into high-temperature high-density magnetized plasma targets with higher density and temperature than a single FRC plasma before collision; and the external pulse driving power source discharges to drive implosion in a solid sleeve to conduct quasi-adiabatic compression of the high-temperature high-density magnetized plasma targets, so that the temperature and density of the plasma targets rise to meet fusion ignition conditions.
