    Abstract: An electron-beam controller (EBC) capable of controlling the power in an electron-beam is disclosed. The EBC can be implemented with an emitter, an extractor, a current mirror, and an input current having a magnitude responsive to the desired electron beam current. An EBC suited for low-efficiency emitters is also disclosed. A method for controlling the power intensity of an electron-beam over time is also disclosed. The method includes the steps of: (1) providing an emitter at a first voltage, (2) providing a target at a second voltage, (3) introducing an extractor at a controllable third voltage, (4) estimating the actual electron beam energy by sensing the emitter current; and (5) adjusting the third voltage in response to the sensed emitter current.

    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.
