Abstract:
Disclosed are apparatus and method for obtaining energy from high electrical charge density entities. The energy may be received by the conductor of a traveling wave device positioned along the path which the propagating entities follow. Multiple traveling wave devices may be combined. Energy output from a traveling wave device may also be directed to the generation of a subsequent such entity. Thermal energy may also be obtained from an EV.
Abstract:
A method and apparatus are disclosed for producing microwave radiation wherein a generally stable, high-beta, relativistic electron plasma is formed in a static magnetic field of a suitable enclosure either by an external microwave source or in situ within the plasma by means of at least one pair of steady-state interacting energetic electron beams, a convectively unstable wave then being created in the confined plasma either internally in an oscillator mode or externally in an amplifier mode by means of an external launcher for producing a pulse of relatively intense microwave radiation at a frequency near a local electron gyrofrequency. The above steps or functions are preferably sequentially repeated with sequential pulses of microwave radiation being withdrawn from the enclosure, focused by quasi-optical means and directed toward a target including electronic circuitry, so that the beam of sequential pulses is coupled into the electronic circuitry for developing substantial amounts of energy therein.
