System and method for plasma generation and compression

A system for generating and compressing magnetized plasma comprising:

• a plasma generator for generating magnetized plasma, the plasma generator having an outlet;
• an elongated central axial shaft extending along a longitudinal axis of the system;
• a plurality of gas valves configured to inject a gas in the plasma generator;
• a flux conserver having an inner evacuated cavity and an opening in fluid communication with the outlet of the plasma generator, the central axial shaft extending out of the plasma generator into the flux conserver such that an end of the central axial shaft being in contact with the flux conserver, the generated magnetized plasma being injected into the inner cavity of the flux conserver through the outlet of the plasma generator;
• a formation power circuit configured to provide a formation power pulse to the plasma generator to ionize the injected gas and generate magnetized plasma;
• a shaft power circuit configured to provide a shaft power pulse to the central axial shaft to generate a toroidal magnetic field into the flux conserver, a duration of the shaft power pulse being longer than a duration of the formation power pulse;
• a plasma compression driver configured to compress the plasma contained in the flux conserver during a plasma compression time;
• and
• a controller configured to control a trigger time of the formation power circuit to provide the formation power pulse separately from the shaft power pulse,
• wherein the shaft power circuit is configured to provide at least one additional shaft current pulse to increase a plasma toroidal field during the plasma compression time to maintain a ratio of the plasma toroidal field to a plasma poloidal field at a pre-determined value during the plasma compression time,
• wherein the controller is configured to provide timing of the at least one additional shaft current pulse based on at least one of a triggering time of the plasma compression driver and a compression trajectory.
