Abstract: The current disclosure is related to a downhole tool that comprises an electronic photon generator and at least one detector. The electronic photon generator comprises a cathode configured to emit electrons, a first target configured to generate photons when struck by the electrons, a second target configured to generate photons when struck by the electrons, and a beam steering device that directs the electrons to a first or second target. The at least one detector is configured to detect at least some of the photons emitted by the first target and at least some of the photons emitted by the second target.

Abstract: A radiation generator may include an elongate generator housing having a proximal end and a distal end, a target electrode within the housing at the distal end thereof, a charged particle source within the housing at the proximal end thereof to direct charged particles at the target based upon a first biasing potential, and a field shaping electrode within the housing and adjacent the source to shape a field within the housing. At least one accelerator electrode may be within the housing on an opposite side of the field shaping electrode from the source to accelerate charged particles from the source to the target based upon a second biasing potential different than the first biasing potential. The field shaping electrode may be electrically floating so that the charged particles are directed from the source to the target without applying a biasing potential to the field shaping electrode.

Abstract: A wellhead container for a geothermal system includes a base configured to engage a bottom of a recess within a ground. The recess extends vertically from the bottom of the recess to a surface of the ground, the base includes at least one first opening, and the at least one first opening is configured to receive a drilling string. The wellhead container includes a top configured to support a load applied by a drilling machine to the wellhead container. The top includes second openings, and each second opening is configured to receive the drilling string. The wellhead container includes a sidewall extending along a vertical axis between the base and the top. The sidewall is configured to position an upper surface of the top substantially flush with the surface of the ground, and the sidewall is configured to transfer at least a portion of the load to the base.

Abstract: A radiation generator is provided that includes a target, a cathode to emit electrons in a downstream direction toward the target, a first conductive member downstream of the cathode, and a second conductive member downstream of the cathode. The first and second conductive members have a potential difference with the cathode such that a resultant electric field accelerates the electrons toward the target. A diagnostic current in the second conductive member and a target current in the target may be measured, and an electrical property of the first conductive member may be adjusted based upon the diagnostic current and the target current.

Abstract: The present disclosure describes a downhole tool including an electrically operated radiation generator that selectively output radiation to a surrounding environment based at least in part on supply of electrical power; and a control system that determines likelihood of exposing living beings in the surrounding environment to output radiation by determining whether one or more check conditions is met; determine that each of the one or more check conditions is met before instructing the electrically operated radiation generator to output radiation; and instruct the electrically operated radiation generator to cease output of radiation when at least one of the one or more check conditions is no longer met.

Abstract: An energy management system for enhancing design and operation of a distributed energy resource system includes a two-level design system and a hierarchical optimization-based control system. The two-level design system includes a top-level designer configured to coordinate decentralized bottom-level designers for individual energy resources to seek a global target for the designed distributed energy resource system that satisfies the energy demand of a target deployment location within a confidence level, and multiple bottom-level designers configured to enhance detailed designs of local energy sub-systems. The hierarchical optimization-based control system include a primary controller configured to determine a long-term operational schedule based on long-term constraints and future events at a first level, one or more secondary controllers configured to control daily orchestrations of the distributed energy resource system during operation at a second level, and multiple tertiary controllers and aggregators configured to rapidly adjust various hardware at a third level.

Abstract: A downhole tool may include a high-voltage power supply disposed within a housing to transform input power to the downhole tool from a first voltage to a second voltage greater than the first voltage. The high-voltage power supply may include an array of capacitors, which may include multiple rows of capacitors. The rows of capacitors may be parallel with a symmetric cross section as viewed from an end of the array of capacitors. The high-voltage power supply may also include diodes electrically coupled to the array of capacitors.

Abstract: A system is disclosed for downhole logging. The system comprises a photon source configured to generate photons at different endpoint energies; at least one radiation detector configured to detect photons after interactions with a wellbore, a geological formation surrounding the wellbore, or both; an energy detection system configured to determine an endpoint energy of the photon source; and a processing system configured to determine properties of a wellbore, a geological formation, or both, based on photons detected at the at least one radiation detector and the endpoint energy determined by the energy detection system.
