Abstract: 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.

Abstract: The present disclosure describes a neutron generator including an ion source that generates ions; a target that outputs neutrons when the ions impact the target; one or more power supplies that supply electrical power to the ion source and the target; and a control system. The control system determines one or more rules that describe relationships between operational parameters, useful life, reliability, neutron output, environment, and constraints of the neutron generators; determines one or more operational parameter setpoints based at least in part on the one or more rules; and instructs the one or more power supplies to adjust electrical power supplied to the ion source, the target, or both based at least in part on the one or more operational parameter setpoints.
