Abstract: The present invention relates to an X-ray tube, having a structure enabling capturing of a clear magnified transmission image and enabling increase of a magnification factor of the magnified transmission image, and an X-ray source including the X-ray tube. In the X-ray tube, X-rays are generated by making electrons from an electron gun incident onto an X-ray target of an anode, disposed inside an anode housing unit, and the generated X-rays are taken out from an X-ray emission window. In particular, the anode housing unit has a pair of conductive flat portions disposed parallel to a reference plane, orthogonal to an electron incidence surface of the X-ray target, and so as to sandwich the X-ray target. The reference plane contains a first reference line, joining an electron emission exit center of the electron gun and an electron incidence surface center of the X-ray target, and a second reference line, being a straight line intersecting the first reference line on the electron incidence surface of the X-ray target and joining the electron incidence surface center and an X-ray emission window center.

Abstract: The present invention aims to suppress calorific value and prolong a lifetime of an apparatus that generates soft X-rays. Thus, the present invention provides a static elimination apparatus that includes an emitter as an electron emitting portion and a target, in which a thin film formed of diamond particles each having a particle size of 2 nm to 100 nm is formed on a surface of the emitter. The thin film has a diamond XRD pattern in an XRD measurement and, in a Raman spectroscopic measurement, a ratio of an sp3 bonding component to an sp2 bonding component within the film of 2.5 to 2.7:1. When a DC voltage is applied to the emitter, with a threshold electric field intensity of 1 V/μm or less, electrons larger in number than the prior art are emitted from the emitter and moreover, a temperature of the emitter is hardly increased, thus obtaining a longer lifetime.

Abstract: Generation of 2 μW average output power at 13.9 nm from a table-top laser-pumped Ni-like Ag laser operating at 5 Hz repetition rate using a silver-coated helical target which is rotated and advanced such that the target surface is renewed between pulses, is described. Greater than 2×104 soft x-ray laser pulses were obtained using a single target. Similar results were obtained at 13.2 nm for Ni-like Cd using a cadmium-coated target. Uninterrupted operation of laser-pumped soft x-ray lasers at a repetition rates of about 10 Hz for periods of several hours enables the generation of pulsed, high average power soft x-rays for applications. Other embodiments of the renewable laser target are described.

Abstract: An anode for an X-ray source is formed in two parts, a main part and a collimating part. The main part has the target region formed on it. The two parts between them define an electron aperture through which electrons pass to reach the target region, and an X-ray aperture through which the X-rays produced at the target leave the anode. The anode produces at least the first stage of collimation of the X-ray beam produced.
