Abstract: In an X-ray radiation source, a counter wall made of alkali-containing glass, out of walls of a housing of an X-ray tube, is sandwiched between a filament and an electric field control electrode to each of which a negative high voltage is applied. This configuration prevents an electric field from being generated in the counter wall and thus suppresses precipitation of alkali ions from the glass. Therefore, it prevents change in potential relationship between electrodes at different potentials such as the filament, grid, and target and enables stable operation to be maintained, without occurrence of a trouble of failure in maintaining a desired X-ray amount.

Abstract: An inspection system for scanning cargo and vehicles is described which employs an X-ray source that includes an electron beam generator, for generating an electron beam; an accelerator for accelerating said electron beam in a first direction; and, a first set of magnetic elements for transporting said electron beam into a magnetic field created by a second set of magnetic elements, wherein the magnetic field created by said second set of magnetic elements causes said electron beam to strike a target such that the target substantially only generates X-rays focused toward a high density section in the scanned object, which is estimated in a second pulse using image data captured by a detector array in a first pulse. The electron beam direction is optimized by said X-ray source during said second pulse to focus X-rays towards said high density section based on said image data in said first pulse.

Abstract: An x-ray source comprising a housing, in which a target in the form of an ionized cloud based on metal vapour is provided. The ionized cloud can be excited by means of an electron beam for emitting monochromatic x-rays. The low atom density advantageously produces only a little braking radiation. The robustness of the plasma with respect to the inevitable thermal energy input is also advantageous with respect to the solid target materials. The cloud can be filled at any time with target material which can be vaporised by means of an electric arc. A method for producing x-rays with the above-mentioned x-ray source is also provided. The use of an x-ray source for emitting monochromatic x-rays for x-raying a body is further provided.
