    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: Examples of a plasma acceleration and compression device are described. The device includes a plasma accelerator with a high compression funnel section extending from an inlet of the accelerator and an elongated section connected to the high compression funnel section that can extend from the end of the funnel section to an accelerator's outlet. The funnel section can be a cone with a steep tapering while the elongated section can have a mild, gentle, tapering along its length toward the outlet. The device further includes a power source for providing a current pulse to the accelerator to generate a pushing flux to accelerate and compress a plasma torus throughout the accelerator. The current pulse can be so shaped so that the current pulse behind the plasma torus at the outlet of the elongated section is significantly smaller than the current pulse at the first end of the elongated section while the pressure of the plasma torus at the outlet of the elongated section is greater than the pressure of the plasma torus at the beginning of the elongated section.
