Abstract: Heat dissipation of a target is enhanced in a transmissive X-ray generating apparatus where an anode member constitutes a part of a container. An anode member configured to hold a target is divided into an outer anode member, which is configured to hold the target and is connected to a container, and an inner anode member, which is joined to an insulating tube and is closer to an electron emitting portion than the outer anode member is. The outer circumferential surface of the inner anode member is joined to the outer anode member via a joining member. Heat generated by the electron emitting portion is dissipated mainly from the inner anode member via the insulating tube, or directly, to an insulating liquid.

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 x-ray source is described. During operation of the x-ray source, an electron source emits a beam of electrons. This beam of electrons is focused to a spot on a target by a magnetic focusing lens. In response to receiving the beam of focused electrons, the target provides a transmission source of x-rays. Moreover, a repositioning mechanism selectively repositions the beam of focused electrons to different locations on a surface of the target based on a feedback parameter associated with operation of the x-ray source. This feedback parameter may be based on: an intensity of the x-rays output by the x-ray source; a position of the x-rays output by the x-ray source; an elapsed time during operation of the x-ray source; a cross-sectional shape of the x-rays output by the x-ray source; and/or a spot size of the x-rays output by the x-ray source.
