Abstract: Examples of a pressure wave generator configured to generate high energy pressure waves in a medium are disclosed. The pressure wave generator can include a sabot carrying a piston. The sabot can further comprise a locking means to lock the piston in a fixed position when the locking means are activated. When the locking means are in a deactivated position, the piston can be released and can move at least partially away from the sabot. The sabot carrying the piston can be disposed within an inner bore of a housing of the pressure wave generator and can move within the inner bore of the housing from its first end toward its second end along a longitudinal axis of the bore. A transducer can be accommodated in the second end of the housing. The transducer can be coupled to the medium and can convert a portion of the kinetic energy of the piston into a pressure wave in the medium upon impact of the piston with the transducer. The sabot carrying the piston can be accelerated by applying a motive force to the sabot. Once accelerated within the inner bore of the housing the sabot can be decelerated by applying a restraining force to the sabot while the piston can be released at least partially from the sabot to continue to move toward the transducer until it impacts the transducer. Examples of methods of operating the pressure wave generator are disclosed.

Abstract: A plasma compression driver is connected to a plasma containment vessel containing a liquid medium that forms a liquid liner containing plasma, and comprises a pair of coaxially aligned pistons that are sequentially driven towards the liquid liner. A pusher bore containing a pusher piston is coaxial with and has a smaller diameter than a driver bore containing a driver piston such that an interconnecting annular face surface is defined at the junction of the driver and pusher bores. During the compression operation, a prime mover accelerates the driver piston towards the pusher piston and compresses a compression fluid, which accelerates the pusher piston and pushes the liquid medium in the pusher bore into the vessel, causing the liquid liner to collapse, and compressing the plasma. Outward forces on the vessel wall caused by compression driver recoil and increased vessel pressure is counteracted by an inward force applied by the compression fluid on the annular face surface during the compression operation.

Abstract: 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.

Abstract: Examples of a jet control device are described. The jet control device can comprise a jet deflecting member that is configured to intercept and/or collide with a high speed jet emerging from a jet formation location. The interaction of the jet deflecting member and the jet can cause the high speed jet to be dispersed into a plurality of jets with a number of flow directions which may be sideways to an initial direction of the high speed jet. In one embodiment the deflecting member can include a liquid guide formed by injecting a fluid out of an outlet nozzle so that the liquid guide extends longitudinally away from the outlet nozzle. In another embodiment the deflecting member can include an array of solid pellets injected through an outlet in a direction of the emerging high speed jet and configured to collide with the emerging jet thereby deflecting its initial direction.

Abstract: A method and system for stably generating and accelerating magnetized plasma comprises ionizing an injected gas in 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.
