Abstract: An x-ray device utilizes a band of material to exchange charge through tribocharging within a chamber maintained at low fluid pressure. The charge is utilized to generate x-rays within the housing, which may pass through a window of the housing. Various contact rods may be used as part of the tribocharging process.

Abstract: The present disclosure relates to multi-layer X-ray sources having decreased hydrogen within the layer stack and/or tungsten carbide inter-layers between the primary layers of X-ray generating and thermally-conductive materials. The resulting multi-layer target structures allow increased X-ray production, which may facilitate faster scan times for inspection or examination procedures.

Abstract: According to one embodiment, a device includes an instruction unit which records in a recording medium, event-related data of when an event is detected and monitoring data of when the event occurs, and a display data output unit which outputs from the recording medium and plays as display data, the event-related data and a part of the monitoring data corresponding to the event-related data. If there is a specification input to the displayed event-related data, the monitoring data corresponding to the event-related data is played.

Abstract: Systems and methods are provided for generating X-ray pulses during X-ray imaging. A high voltage of an X-ray tube is automatically switched off. The tube voltage decays and upon reaching a predefined threshold value of the tube voltage or a predefined waiting time after switching off the high voltage, a grating voltage of a grating arranged between an emitter and an anode of the X-ray tube is automatically switched on. No electrons reach the anode from the emitter, and the tube current drops to the value zero.

Abstract: The present disclosure provides a reliable X-ray generating tube that forms a focus with a stable size and shape. The X-ray generating tube includes an electron gun including an electron emitting portion, a plurality of grid electrodes, and an insulating support member that supports the plurality of grid electrodes. The electron gun includes a conductive section that hides the insulating support member to prevent the insulating support member from being directly viewed from an electron through path of electrons emitted from the electron emitting portion and passing through the grid electrodes.

Abstract: Improved heat transfer from an x-ray tube can be accomplished with a heatsink surrounding at least part of an x-ray tube. The heatsink can be electrically connected to an anode of the x-ray tube and can be an electrical current path. The heatsink can include a plurality of protrusions extending radially outward from the x-ray tube and can be a single, integral substance extending from an inner-surface of the heatsink to a distal-end of the protrusions.

Abstract: An x-ray tube can provide x-ray spot stability, even for a small x-ray tube. The x-ray tube can have small target displacement, where target displacement is a displacement of the target material, towards the electron-emitter, along a longitudinal-axis of the anode, from x-ray powered-off state to stable operation, based on elongation of the anode. The x-ray tube can include a heatsink with an array of fins extending away from a base in opposite directions. A first fan can be attached to one end of the array of fins, oriented to face the base, and configured to direct an airstream towards the base. A second fan can be attached to opposite ends, oriented to face away from the base, and configured to draw the airstream from the base. Plate(s) can be located on sides of the fins to direct air flow from the first fan to the second fan.

Abstract: An X-ray emitter has an X-ray tube which contains a vacuum envelope in which an emitter and an anode are disposed. The emitter can be heated by an external flat emitter filament supply. Accordingly the emitter is configured as a filament emitter and an interface circuit is arranged between the filament emitter and the flat emitter filament supply. In this manner, a flat-emitter-based X-ray emitter can be replaced by a filament-emitter-based X-ray emitter in an X-ray emitter system without any configuration changes.
