X-ray source voltage shield
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.
X-RAY MACHINE
An x-ray apparatus includes a vacuum chamber that includes a window for exit of x-rays. Electrons are generated at a cathode within the vacuum chamber and accelerated toward a target anode associated with the window. An x-ray generating layer is included as a surface of the target anode to receive the electrons emitted by the cathode and to create x-rays. A blocking path blocks over 70% of the free electrons reaching said target anode from continuing on to exit through the window, while allowing x-rays leaving the x-ray generating layer to continue along the selectively blocking path to exit through the window. The x-ray apparatus is capable of operating at low voltage and relatively high power to reduce the necessary shielding and the corresponding weight of the apparatus yet allow more ready absorption of x-rays by items being irradiated.
COMPONENT OR ELECTRON CAPTURE SLEEVE FOR AN X-RAY TUBE AND X-RAY TUBE HAVING SUCH A DEVICE
A component part in a vacuum area of an X-ray tube with an opening through which an electron beam is guided. The component part includes a base body made of a first material, wherein the first material is a metal. Arranged on a surface forming the opening is a second material having an atomic number which is smaller than an atomic number of the first material. A target support is attached to an end of the component part. The target support supports a target which is aligned with a lens diaphragm formed at the end of the component part. The target support has a base body made of a first material which is a metal, and a second material formed on a surface of the base body that is selectively exposed to the electron beam and which extends between the target and the lens diaphragm.
A SHIELDED X-RAY RADIATION APPARATUS
A shielded X-ray radiation apparatus is provided comprising an X-ray source, an X-ray attenuation shield including an elongate cavity to house the X-ray source and incorporating a region to accommodate a sample, a neutron attenuation shield, and a gamma attenuation shield. The neutron attenuation shield is situated adjacent to and substantially surrounds the X-ray attenuation shield and the gamma attenuation shield is adjacent to and substantially surrounds the neutron attenuation shield. In some embodiments a removable sample insertion means is provided to insert samples into the elongate cavity and which is composed of adjacent blocks of material, each respective block having a thickness and a composition which substantially matches the thickness and a composition of one of the X-ray attenuation, neutron attenuation and gamma-ray attenuation shields.

Methods and systems for composite radiation shielding parts
Various methods and systems are provided for a radiation shielding component including a plurality of parts fused together by metal infiltrated through junctions between adjacent, interconnected parts. In one embodiment, members on a side of a panel may be interlocked with indentations on a side of another and then metal may be infiltrated through a junction between the two panels to fuse the adjacent panels.

An X-ray beam is generated in an interaction zone of an electron beam and a target, the zone being an annular layer of a molten fusible metal in an annular channel of a rotating anode assembly. The channel has a surface profile which prevents slopping of the molten metal in the radial direction and in both directions along the rotation axis. The liquid-metal target forms a circular cylindrical surface due to the centrifugal force acting thereupon. The linear velocity of the target is preferably higher than 80 m/s; in a vacuum chamber, a changeable membrane made of carbon nanotubes is installed in the X-ray beam path and a protective screen with apertures for electron beam entry and X-ray beam exit is arranged around the interaction zone. The technical result consists in an X-ray source with increased power, brightness, lifetime and ease of use.
