Abstract: A device for providing for electron excited x-ray fluorescence may include means for driving two contacting surfaces against each other in a low fluid pressure environment, such that high energy electrons strike a sample under test and provide for x-ray fluorescence of the sample. The sample under test may be in or on a sample holder, whose position with respect to the contacting surfaces is adjustable. For example, the sample holder may be positionable to be a different distances from the contacting surfaces.

Abstract: A portable CT scanner may include a rotatable frame with separable portions. An x-ray source may be coupled to one portion of the rotatable frame, and an x-ray detector may be coupled to another portion of the rotatable frame. During storage and transportation, one portion of the rotatable frame may be housed in a first enclosure, and another portion of the rotatable frame may be housed in a second enclosure. When operation of the scanner is desired, the two enclosures may be connected, and/or the rotatable frame portions may be connected with the enclosures abutting one another, to allow for rotation of the rotatable frame about an aperture formed by the enclosures.

Abstract: A device for generating x-rays has an enclosing vessel having a structure suitable to provide an enclosed space at a predetermined fluid pressure, wherein the enclosing vessel has a window portion and a shielding portion in which the shielding portion is more optically dense to x-rays than the window portion; a mechanoluminescent component disposed at least partially within the enclosing vessel; and a mechanical assembly connected to the mechanoluminescent component. The mechanical assembly provides mechanical energy to the mechanoluminescent component while in operation, and at least some of the mechanical energy when provided to the mechanoluminescent component by the mechanical assembly is converted to x-rays.

Abstract: A high energy radiation generator utilizes sliding friction in a low pressure environment to generate high energy radiation, for example x-rays. The sliding friction may be generated by sweeping one material against a second material, for example rotating a surface of a rotor against a membrane, in the presence of an electron target, which may be one of the first material or the second material, or a different material.

Abstract: An x-ray source for generating x-rays with at least one narrow energy band includes an enclosing vessel, a first contact arranged with a first contact surface in the enclosing vessel, a second contact arranged with a second contact surface in the enclosing vessel, and an actuator assembly operatively connected to at least one of the first and second contacts. The actuator assembly is structured to cause the first contact surface and the second contact surface to repeatedly come into contact, and separate after making contact, while in operation. The first contact surface is a surface of a first triboelectric material and the second contact surface is a surface of a second triboelectric material, the surface of the first triboelectric material having a negative triboelectric potential relative to the surface of the second triboelectric material.

Abstract: An x-ray source includes an enclosing vessel, a first roller arranged at least partially within the enclosing vessel, a second roller arranged at least partially within the enclosing vessel and to be in rolling contact with the first roller, and a drive assembly operatively connected to at least one of the first and second rollers. The drive assembly causes the first and second rollers to rotate while in contact to bring portions of the first and second rollers into and out of contact within the enclosing vessel as the first and second rollers rotate. The first roller has a surface at least partially of a first triboelectric material and the second roller has a surface at least partially of a second triboelectric material, the first triboelectric material having a negative triboelectric potential relative to the second triboelectric material.
