Claims
- 1. Apparatus for generating high-intensity x-rays comprising:an electron beam source comprising a betatron having a toroidal ring for generating an electron beam; an x-ray source comprising a thin radiator for generating x-rays from said electron beam; wherein said thin radiator is placed inside said betatron toroidal ring such that the path of said electron beam intersects said thin radiator.
- 2. Apparatus as in claim 1, wherein said thin radiator is designed to be thin enough such that individual electrons in said electron beam penetrate and pass through said thin radiator a plurality of times while orbiting inside said betatron toroidal ring.
- 3. Apparatus as in claim 1, wherein said thin radiator comprises a thin crystal oriented such that the electron beam direction and the exit port or slits relative to the crystal planes are at the Bragg condition either in the Bragg geometry or the Laue geometry; and x-ray emission known as parametric x-ray emission is generated.
- 4. An apparatus as in claim 1 where the target comprises a crystal oriented such that the electron-beam direction is along one axis of the crystal and that the said electron-beam is captured and channeled along the said crystal axis; and x-ray emission known as channeling radiation is generated.
- 5. Apparatus as in claim 1, wherein the target comprises a foil stack composed of series of thin foils such the electron beam penetrates and passes through said foils generating x-ray emission known as transition radiation.
- 6. Apparatus as in claim 1, wherein said thin radiator is selected from the group consisting of a channeling radiator, a parametric radiator, a transition radiator, a resonance transition radiator, or a combination thereof.
