1. An x-ray generating device comprising:
- a sliding surface;
a frictional material band in contact with the sliding surface and at least partially encompassing the sliding surface;
a motor whose operation causes the frictional material band to rotate and to slide over the sliding surface, wherein the frictional material band and the sliding surface are comprised of materials such that varying the contact between the frictional material band and the sliding surface generates a relative charge imbalance; and
an electron target in proximity to a release point of the frictional material band when sliding over the sliding surface;
wherein at least the electron target and the release point are contained in a controlled fluid pressure environment.

Abstract
An x-ray device utilizes a band of material to exchange charge through tribocharging within a chamber maintained at low fluid pressure. The charge is utilized to generate x-rays within the housing, which may pass through a window of the housing. Various contact rods may be used as part of the tribocharging process.

11. A method of generating x-rays comprising:
-
providing a contact material sliding surface; providing a frictional material band, wherein the frictional material band comprises a loop with an interior and an exterior; sliding the interior of the frictional material band across the contact material sliding surface in a controlled, low fluid pressure environment, such that varying the contact between the frictional material band and the contact material sliding surface near an edge of the contact material sliding surface generates a relative charge imbalance, wherein the edge is defined as a portion of the contact material sliding surface in which the frictional material band releases contact therefrom; providing an electron target close to the edge of the contact material sliding surface such that the frictional material band exiting contact with the contact material sliding surface discharges electrons to the electron target; and generating x-rays from the collision of electrons with the electron target. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
