A direct converter for an axisymmetric mirror confinement system provides a set of radially symmetric vanes charged to capture ions escaping along the axis of the confinement system and to convert their energy to electrical power. An electron trap positioned before the charged vanes uses a magnetic field to divert and collect electrons, separating them from the ions, and may support a radial electric field providing plasma control. The charged vanes may be constructed of or have a coating of a getter material absorbing neutrals derived from those ions after capture.

A quasi-pulsed FRC deuterium-deuterium fusion reactor and its self-sustaining nuclear fuel cycle steady-state power generation method are disclosed. The reactor comprises a linear vacuum chamber, an FRC plasma formation zone, a collision fusion zone, a conical transition section, a plasma formation coil, a fast compression coil, a magnetic mirror coil assembly, a deuterium-tritium feeding system, a zoned vacuum pumping system, and a pulsed power control system. The magnetic mirror coil assembly is located near the collision fusion zone in the conical transition section. Within a single pulse cycle, it sequentially executes four functional modes: compression assistance, magnetic mirror reflection, magnetic bottle confinement, and recovery attenuation. During the recovery attenuation mode, it is reused as a direct energy conversion induction coil. The operation mode employs a trace amount of tritium to catalyze deuterium-deuterium fusion. Tritium and helium-3 are confined to participate in the secondary reaction through magnetic mirror confinement. Between pulses, the difference in chemical adsorption of tritium and the difference in cryogenic condensation of helium-3 are utilized to achieve selective recovery of the two components, forming a quasi-pulsed self-sustaining operation. The power is then converted into steady-state electrical power and connected to the grid via a rectification-storage-inverter system, realizing the internal recycling of tritium and helium-3.
