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： A neutron generator includes a sealed envelope providing a low pressure environment for a gas of hydrogen isotope(s). One end of the envelope defines an ion source chamber. A target electrode is disposed at the other end of the envelope. An extraction electrode is spaced apart from the target electrode by an accelerating gap. The extraction electrode bounds the ion source chamber. An RF antenna is disposed external to the sealed envelope in the vicinity of the ion source chamber. The RF antenna is used to transmit time-varying electromagnetic fields within the ion source chamber for producing plasma therein. The extraction electrode operates at a positive high voltage potential and the target electrode operates at or near ground potential in order to provide an electric field gradient that accelerates ions of the plasma towards the target electrode to induce collisions of ions with target material, thereby causing fusion reactions that generate and emit neutrons from the target material. High voltage insulation is disposed between the RF antenna and both the ion source chamber and the extraction electrode for electrically insulating the RF antenna operating at or near ground potential from the high voltages of the ion source chamber and the extraction electrode.
