Abstract
Abstract An X-ray source for producing high intensity X-rays. The X-ray source includes a vessel filled with an inert gas. An energizing mechanism such as a magnetic coil causes the gas to enter a pinch, plasma state which produces high intensity X-rays. The vessel includes a window through which the X-rays are radiated. In a second embodiment, a laser or electron beam bombards a crystal of selected material to produce the X-rays. The material, when gasified, does not interfere with radiation of the X-rays.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
110 words
An X-ray source comprising a vessel, inert gas filling said vessel, and energizing means for causing said inert gas to enter a plasma state, said inert gas when placed in a plasma state producing X-rays, said vessel including window means for permitting said X-rays to radiate out of said vessel, said energizing means including a pair of spaced electrodes on said vessel, said electrodes, when energized, causing said inert gas to enter the plasma state, said energizing means further including coil means around said vessel for generating a magnetic field to cause said plasma to enter the pinch state so that X-rays are produced and radiated through said window means.
