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 include an electron-emitter, which can include a tube-shape with a minimum inside diameter of at least 0.5 millimeters. The electron-emitter can provide field-emission of electrons, and thus can avoid the electrical power required for heating, and can avoid degradation due to high temperature of, a thermionic-emission electron-emitter. This type of electron-emitter, with a tube-shape, can have a relatively large electron-emission region, allowing high electrical current without excessive current density.

Abstract: An electrostatic dissipation device 10 can comprise an elongated enclosure 11 with a longitudinal axis 12. An x-ray source 13 can be oriented to emit x-rays 16 inside of and along the longitudinal axis 12. A fluid-flow device 14 can be oriented to cause fluid to flow across the x-ray source 13 then inside of and along the longitudinal axis 12, the fluid being ionized by the x-rays 16, forming ionized fluid, then out of the elongated enclosure through outlet opening(s) 15. The arrangement of the x-ray source 13 and the fluid-flow device 14 can allow (1) fluid from the fluid-flow device 14 to cool the x-ray source 13, and (2) ion generation along the length of the elongated enclosure 11.

Abstract: X-ray transparent insulation can be sandwiched between an x-ray window and a ground plate. The x-ray transparent insulation can include aluminum nitride, boron nitride, or polyetherimide. The x-ray transparent insulation can include a curved side. The x-ray transparent insulation can be transparent to x-rays and resistant to x-ray damage, and can have high thermal conductivity. An x-ray window can have high thermal conductivity, high electrical conductivity, high melting point, low cost, and matched coefficient of thermal conductivity with the anode. The x-ray window can be made of tungsten. For consistent x-ray spot size and location, a focusing plate and a filament can be attached to a cathode with an open channel of the focusing plate aligned with a longitudinal dimension of the filament. Tabs of the focusing plate bordering the open channel can be bent to align with a location of the filament.

Abstract: A shield around an x-ray tube, a voltage multiplier, or both can improve the manufacturing process by allowing testing earlier in the process and by providing a holder for liquid potting material. The shield can also improve voltage standoff. A shielded x-ray tube can be electrically coupled to a shielded power supply.

Abstract: In order to reduce the amount of electrical insulation needed for voltage isolation of large voltages generated by a voltage multiplier, the voltage multiplier can be shaped to smooth out electric field gradients. The voltage multiplier can comprise multiple sections, each section located in a different plane. The voltage multiplier can comprise a negative voltage multiplier and a positive voltage multiplier, each inclined at different angles with respect to each other. The voltage multiplier can include a curved shape.
