Abstract:
1. X-ray generation apparatus including: an elongated target body and a mount from which the body projects to a tip remote from the mount, said mount providing a heat sink for said target body, the target body including at least one layer, displaced from said tip along a longitudinal axis of the elongated target body, of a substance that, on being irradiated by a beam of electrons of suitable energy directed onto the target body from laterally of the elongate target body, generates a source of x-ray radiation from a volume of interaction of the electron beam with said at least one layer of the target body; and an aperture spaced from said tip in the longitudinal direction of said target body, to define a beam or cone of said x-ray radiation emitted generally about said tip.
