Abstract: An X-ray tube includes an electron gun unit, a target that generates X-rays, and a vacuum housing unit. The vacuum housing unit has a metal housing unit for supporting the target and a bulb unit formed of an insulating material and connected to the metal housing unit. The electron gun unit has a focusing electrode portion at an end portion on an emission side of the electrons, the focusing electrode portion having a tubular shape for focusing the emitted electrons. In the electron gun unit, at least a part of the focusing electrode portion is supported by the bulb unit so as to be located in the metal housing unit. When viewed from an X-ray generation position on the target, the focusing electrode portion blocks a line of sight from the X-ray generation position to the bulb unit.

Abstract: A portable XRF analyzer includes a hand shield and a handle. In one embodiment, the XRF analyzer further comprises a power component spaced-apart from an engine component. The handle and the hand shield extend in parallel between the engine component and the power component, attaching the engine component to the power component. In another embodiment, the XRF analyzer further comprises two housing portions, each integrally formed in a single, monolithic body formed together at the same time. The two housing portions are joined together to form an XRF analyzer housing. In another embodiment, the hand shield is shorter than the handle.

Abstract: A method for inducing chemical reactions using X-ray radiation comprises generating an irradiation volume within the interior of a reaction vessel by introducing X-ray radiation into the volume, in which two or more reactants are introduced. With respect to the two or more reactants and any subsequently created intermediate reactant or reactants, the aggregate extent to which the foregoing reactants are to be ionized to any degree is selectively controlled, and the average degree of ionization in the irradiation volume, from partial to total, of that portion of the foregoing reactants which is to be ionized is selectively controlled, through control of the fluence and energy of the X-ray radiation, to thereby induce selective reactions of reactants to occur in the irradiation volume. One or more reactants may be delivered through a double-walled pipe containing X-ray shielding to prevent their premature irradiation before being injected into the irradiation volume.
