A system for generating magnetized plasma and sustaining plasma's magnetic field comprises a plasma generator for generating magnetized plasma and a flux conserver in which the generated magnetized plasma is injected and confined. A central conductor comprises an upper central conductor and a lower central conductor that are electrically connected forming a single integrated conductor. The upper central conductor and an outer electrode form an annular plasma propagating channel. The lower central conductor extends out of the plasma generator and into the flux conserver such that an end of the inner electrode is electrically connected to a wall of the flux conserver. A power system provides a formation current pulse and a sustainment current pulse to the central conductor to form the magnetized plasma, inject such plasma into the flux conserver and sustain plasma's magnetic field.

System and method for generating plasma and sustaining plasma magnetic field

A method and system for stably generating and accelerating magnetized plasma comprises ionizing an injected gas in a plasma generator and generating a formation magnetic field to form a magnetized plasma with a closed poloidal field, generating a reverse poloidal field behind the magnetized plasma and having a same field direction as a back edge of the closed poloidal field and having an opposite field direction of the formation magnetic field, and generating a pushing toroidal field that pushes the reverse poloidal field against the closed poloidal field, thereby accelerating the magnetized plasma through a plasma accelerator downstream from the plasma generator. The reverse poloidal field serves to prevent the reconnection of the formation magnetic field and closed poloidal field after the magnetized plasma is formed, which would allow the pushing toroidal field to mix with the closed poloidal field and cause instability and reduced plasma confinement.

System and method for generating and accelerating magnetized plasma

Examples of a system for generating and compressing magnetized plasma are disclosed. The system comprises a plasma generator with a first closed end and an outlet, and a flux conserving chamber that is in tight fluid communication with the outlet of the plasma generator such that the generated plasma is injected into an inner cavity of the flux conserving chamber. An elongated central axial shaft is also provided such that the central shaft extends through the outlet of the plasma generator into the flux conserver. The end of the central shaft in connected to the flux conserver. A power source that comprises a formation power circuit and a shaft power circuit is provided to provide a formation power pulse to the plasma generator to generate magnetized plasma, and a shaft power pulse to the central axial shaft to generate a toroidal magnetic field into the plasma generator and the flux conserving chamber. The duration of the shaft power pulse is longer than the duration of the formation power pulse to maintain plasma q-profile at a pre-determined range. During plasma compression the shaft power pulse is increased to match the raise of the plasma poloidal field due to the compression and thus maintain the q-profile of the plasma.

System and method for plasma generation and compression

Embodiments of systems and methods for compressing plasma are disclosed in which plasma can be compressed by impact of a projectile on a magnetized plasma in a liquid metal cavity. The projectile can melt in the liquid metal cavity, and liquid metal may be recycled to form new projectiles.
