Abstract: A device and method for the generation of thermonuclear fusion through the resonant excitation of plasma. A resonant “bounce” effect is observed in shock-heated plasmas driven by a single current pulse with fast current rise-time. The present invention discloses means for resonant excitation of plasma at frequency derivatives of the bounce frequency including harmonics and subharmonics of the fundamental bounce frequency. The resonant excitation power circuit may employ a closed loop feedback circuit with an operational amplifier or be open loop employing a frequency reference and may include any configuration of inductors and capacitors. The reactor may be of any geometry and or configuration including linear pinch, theta pinch, toroidal pinch such as field-reversed configuration, magnetically stabilized pinches such as the tokamak, or may be steady state reactors.
