These two patents described here are interrelated and they cover a "newused" way of X-ray generation. I say "newused" because it picks up where Sir William Crookes and William Konrad Roentgen left it. Although X-ray were first produced in gas discharge tubes, the need for narrow and well focused X-ray beams led to the modern X-ray tube which is polarized (DC operation only) and outputs a very narrow X-ray beam. My friend and colleague Ray Fleming was asked to review an idea of a food sterilization apparatus. What was needed to irradiate foodstuffs on a moving conveyor belt was an X-ray tube emitting a wide X-ray beam at high intensity.
So Ray went back to the basics and he asked himself why not use an electrical discharge in a rarefied gas to generate X-rays. Such an X-ray tube would have a wide beam (in fact it would generate X-rays all around its cylindrical axis) and it would be capable in principle at least to output higher radiation intensities since the X-ray generation would occur over the whole tube volume as opposed to a narrow spot n standard X-ray tubes.
Over the next 18 months we experimented with gas discharges in rarefied gases. We proved that AC is much more efficient than DC and we observed a very interesting resonant phenomenon inside the tube. Our prototype produced X-ray as pedicted, at high intensities which proved to be scary at times.
In the end we had invented a new way of producing vacuum arc discharges, where not only was the power supply resonant but one of the resonant circuit components is the gas discharge tube. We also invented an X-ray tube which used resonant plasma as an X-ray source.
My contribution to this endeavor was three pronged: the power supply, using AC driving instead of DC (which I share with Ray) and separating with appropriate reactances the tube and power supply in such a way that the tube resonates both by itself at high frequencies and in tandem with the power supply at lower frequencies.
You can read more about it, in greater detail at our "mad science" site.
You can check out our patents at the United States Patent and Trademark Office Home Page by searching for numbers: 6,630,799 and 6,765,987.
I also have a mirror of those files on this site: 6,630,799 and 6,765,987.
The pages are stored as TIFF images and you need to install a viewer plugin: for IE IE alternatiff and for the Mozilla family Mozilla alternatiff.
