Abstract: An x-ray laminography imaging system that utilizes a nonplanar anode target to enable objects that are oblique to the direction of projection of electron beams onto the target to be precisely imaged. Because many objects that laminography techniques are used to inspect are oblique or have portions that are oblique, the nonplanar anode target of the present invention enables enables spot patterns to be traced that are parallel to the plane of the object, regardless of whether it is oblique or orthogonal.

Abstract: The invention relates to a device for generating X-rays (31). The device has a source (5) for emitting electrons (27) accommodated in a vacuum space (3). The X-rays are emitted by a liquid metal as a result of the incidence of the electrons. The liquid metal flows through a constriction (13) where the electrons emitted by the source impinge upon the liquid metal. The constriction is bounded by a thin window (23), which is made from a material which is transparent to electrons and X-rays and which separates the liquid metal in the constriction from the vacuum space, and by a wall (25) opposite to the window. According to the invention, the wall (25) has a profile (p) which matches a profile (p′) which the window (23) has, during operation, as a result of a deformation of the window caused by a pressure of the liquid metal in the constriction (13). Thus, it is achieved that the constriction has a predetermined intended cross-sectional area, and a decrease of the flow velocity and an accompanying excessive increase of the pressure at the location of the deformation of the window are prevented.

Abstract: An x-ray tube has a stationary vacuum housing, in which are arranged an electron-emitting cathode and a ring anode with an impact surface on which the electron beam, accelerated by an electrical field, is incident, as well as a deflection system to focus and deflect the electron beam. The ray exit window of the x-ray tube is round, lies in the plane perpendicular to the central axis of the x-ray tube, and terminates one side at the vacuum housing. The impact surface of the ring anode is beveled and is aligned to the ray exit window. A diaphragm is provided in front of the ray exit window that defines a circular opening for the x-ray radiation. The ring anode is surrounded by an annular anode cooling arrangement.

Abstract: A sleeve or cover for preventing the production of secondary x-ray signal contamination from an analytical x-ray tube is disclosed. The x-ray tube includes an evacuated enclosure in which is disposed a cathode and anode. The sleeve or cover is useful in applications such as x-ray fluorescence spectroscopy for improving the spectral purity of the primary stream of x-rays produced by electron bombardment of the anode target surface by the cathode. In one embodiment, the sleeve is disposed about a portion of the anode substrate, and is comprised of beryllium. Electrons back-scattered from the target surface are attracted to the anode substrate and impact the beryllium sleeve, producing secondary x-rays that are not detected by spectroscopic detectors and are therefore not contaminating to the primary x-ray stream.
