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: 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: A therapeutic radiation source includes a spiral-shaped, laser-heated thermionic cathode. A fiber optic cable directs a beam of radiation, having a power level sufficient to heat at least a portion of the electron-emissive surface to an electron emitting temperature, from a laser source onto the cathode. The cathode generates an electron beam along a beam path by thermionic emission, and strikes a target positioned in its beam path. The target includes radiation emissive material that emits therapeutic radiation in response to incident accelerated electrons from the electron beam. The spiral-shaped conductive element has a plurality of spaced apart turns, and is disposed in a vacuum. An interstitial spacing is defined between adjacent turns, so that heat transfer across the spacing between each adjacent turn is essentially eliminated, thereby substantially reducing heat loss in the cathode caused by thermal conduction.
