    Abstract: This invention relates to the use of thick target materials 50 microns and thicker for an x-ray transmission tube; to possible target material compositions including various elements and their alloys, eutectic alloys, compounds, or intermetallic compounds; and applications for utilizing such thick target transmission x-ray tubes. The target comprises at lease one portion of the target with a thickness of 50 microns or greater. The target can be optionally attached to a substrate end-window essentially transparent to x-rays or be thick enough so that no such substrate is required. Applications include producing a high percentage of monochromatic line mission x-rays of said thick target for use in reduced dose medical imaging and other non-destructive testing applications.

    Abstract: The embodiments disclosed herein relate to the controlled generation of X-rays and, more specifically, to the control of electron beams that are used to produce X-rays using one or more electron beam manipulation coils. For example, methods and devices for driving an electron beam manipulation coil, as well as systems using these devices, are provided. The systems are generally configured to maintain a first current though an electron beam manipulation coil using a first voltage source and to switch the first current to a second current using a second voltage source.

    Abstract: A compact apparatus can form multi-X-ray beams with good controllability. Electron beams (e) emitted from electron emission elements (15) of a multi-electron beam generating unit (12) receive the lens effect of a lens electrode (19). The resultant electron beams are accelerated to the final potential level by portions of a transmission-type target portion (13) of an anode electrode (20). The multi-X-ray beams (x) generated by the transmission-type target portion (13) pass through an X-ray shielding plate (23) and X-ray extraction portions (24) in a vacuum chamber and are extracted from the X-ray extraction windows (27) of a wall portion (25) into the atmosphere.

    Abstract: In one example, an x-ray tube includes an evacuated enclosure and an anode disposed with the evacuated enclosure. The anode is configured to receive electrons emitted by an electron emitter. The x-ray tube also includes an evacuated enclosure window disposed within a port of the evacuated enclosure. The evacuated enclosure window includes first and second axes, the first axis being relatively shorter than the second axis. The x-ray tube also includes means for directing coolant flow. The means for directing coolant flow causes coolant to flow across an exterior surface of the evacuated enclosure window in a direction substantially parallel to the first axis.

    Abstract: A multiple wavelength x-ray source includes a multi-thickness target, having at least a first and a second thickness. The first thickness can substantially circumscribe the second thickness. An electron beam can be narrowed to impinge primarily upon second thickness or expanded to impinge primarily upon the first thickness while maintaining a constant direction of the beam. This invention allows the target thickness to be optimized for the desired output wavelength without the need to redirect or realign the x-rays towards the target.
