X-ray micro-target source

摘要

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.
