A composite target for an x-ray tube has a graphite substrate portion and a metal portion, the two portions being bonded together by a platinum braze. A tantalum wetting agent layer on the graphite acts to improve the bond by causing the platinum to better wet the graphite portion.

A high voltage cable connector has a flanged insulating sleeve terminating the cable. The sleeve inserts in an insulating receptacle with some clearance space around it for being occupied by a fluid dielectric medium. The receptacle has a flange which is axially spaced from the flange on the sleeve when the sleeve is fully inserted and secured in the receptacle. A ring element is sealed between the flanges. It defines an annular chamber which communicates with the dielectric medium filled clearance space. A compressible element such as a bellows or diaphragm is disposed in the chamber for accommodating thermal expansion and contraction of the medium or the connector assembly to allow sealing of the system to prevent loss of dielectric and thereby prevent formation of cavities in the medium which could cause electrical breakdown.

High voltage connector for x-ray equipment

A detector for X-radiation or other ionizing radiation comprises a pair of curved metal bars lying in spaced apart parallel planes. Ceramic members are bonded to the respective bars in facing relationship. Each ceramic member has a plurality of radially extending circumferentially spaced grooves facing similar grooves in the other member. A plurality of electrode plates are held in juxtaposed and circumferentially spaced apart relationship by disposing their respective upper and lower edges in the grooves of opposed ceramic members. The faces of adjacent electrode plates define gas-filled gaps in which photoelectron-ion pairs are produced when radiation enters from the front edges of the plates. The above described assembly is disposed within a pressurized gas-filled chamber having an X-ray transmissive window adjacent the front edges of the plates. A cover encloses the chamber. It has insulator feed-throughs for connecting the electrode plates with external electric circuits. Photoelectrons and/or ions, created by the ionizing radiation, are collected on the electrode plates and thereby generate an electrical signal which corresponds to the incident ionizing radiation.

Multicell X-ray detector

An x-ray tube anode has a body or substrate comprised of molybdenum or an alloy thereof and a surface layer on which an electron beam impinges to generate x-rays, comprising an alloy of tungsten, rhenium and molybdenum. A method of making the anode is also disclosed.
