Abstract
X-ray generation apparatus including an elongated target body and a mount from which the body projects to a tip remote from the mount. The target body includes 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 the target body. The mount provides a heat sink for the target body.

X-ray generation apparatus comprising:
- an elongated target body, the target body having a length and a width and formed of respective contiguous layers extending substantially wholly across the width of the body and arranged successively in the longitudinal direction of said target body, each layer comprising a substance that, on being irradiated by a beam of electrons of suitable energy directed onto the target body from laterally of the elongated target body, generates a source of x-ray radiation from a volume of interaction of the electron beam with the respective layer;
- 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;
- and
- wherein the characteristic energies of the x-ray radiation generated by the respective contiguous layers differ for a given incident electron energy.
A method of generating x-ray radiation comprising directing a beam of electrons of suitable energy onto an elongate target body from laterally of the target body, wherein said target body projects from a mount for the body to a tip remote from the mount, and wherein the target body has a length and a width and is formed of respective contiguous layers extending substantially across the width of the body and arranged successively in the longitudinal direction of said target body, each layer comprising a substance that, on being irradiated by said beam of electrons, generates a source of x-ray radiation, said mount providing a heat sink for said target body, wherein the characteristic energies of the x-ray radiation generated by the respective contiguous layers differ for a given incident electron energy.
