摘要： Disclosed is a radiation logging tool, comprising a tool housing; a compact generator that produces radiation; a power supply coupled to the compact generator; and control circuitry. Embodiments of the compact generator comprise a generator vacuum tube comprising a source generating charged particles, and a target onto which the charged particles are directed; and a high voltage supply comprising a high voltage multiplier ladder located laterally adjacent to the generator vacuum tube. The high voltage supply applies a high voltage between the source and the target to accelerate the charged particles to a predetermined energy level. The compact generator also includes an electrical coupling between an output of the high voltage supply and the target of the generator vacuum tube to accommodate the collocated positions of the generator vacuum tube and the high voltage power supply.

摘要： An electron acceleration portion of a Betatron having a vacuum chamber with an interior wall spaced from an exterior wall with a main electron orbit located approximate to the exterior wall and the interior wall. An electron injector has an anode structured and arranged adjacent a wall selected from the group consisting of the interior wall and the exterior wall that is shaped so as to not impede the main electron orbit. There is at least one electron deflection plate disposed approximate an anode end of the anode and the main electron orbit. There can be two electron deflection plates spaced apart that form a gap of a width effective to receive emitted electrons from the electron injector. Such that, there is a voltage potential between the two electron deflection plates that is effective to deflect emitted electrons towards the main electron orbit.

摘要： A multi-directional dispenser cathode has a cathode body that supports a plurality of electron emitters which spanning open portions of the cathode body. Each electron emitter has an inward facing surface and an outward facing surface wherein the inward facing surfaces and an interior wall of the body define an interior volume that contains a heater. To selectively accelerate emitted electrons, an electrically distinct biasing electrode is in spaced relationship to the outward facing surface of each electron emitter and coupled to a biasing power supply effective to provide an intermittent positive voltage potential to the biasing electrode. The distinct biasing electrodes are provided with a positive voltage potential at different times thereby causing an intermittent burst of electrons. Among the applications for intermittent bursts of accelerated electrons are to generate radiation from a particle accelerator.

摘要： A Betatron having a toroidal passageway disposed in a cyclical magnetic field with a main electron orbit circumnavigating the toroidal passageway. Within the toroidal passageway is a first electrode that is spaced apart from a second electrode. The combination of the first electrode and the second electrode define a central space having a first opening and a second opening. A cathode is disposed within the central space. This cathode has a first electron emitter aligned to inject electrons through the first opening and a second electron emitter aligned to inject electrons through the second opening. Electrons injected in a proper direction are accelerated in the main electron orbit. At a time of maximum electron acceleration, the electrons are deflected and impact a target that generates x-rays on impact.
