Patent ID: 7939809

Claim:
An apparatus for extracting a circulating charged particle beam from a synchrotron, said synchrotron having a center, said apparatus comprising: an extraction material; at least a one kilovolt direct current field applied across a pair of extraction blades; and a deflector, wherein the circulating charged particle beam passes through said extraction material resulting in a reduced energy charged particle beam, wherein the reduced energy charged particle beam passes between said pair of extraction blades, and wherein the direct current field redirects the reduced energy charged particle beam through said deflector, wherein said deflector yields an extracted charged particle beam, wherein a radio frequency voltage applied across a pair of betatron oscillation inducing blades induces a betatron oscillation on the circulating charged particle beam, wherein a first distance between said center of said synchrotron and said pair of extraction blades is less than a second distance between said center of said synchrotron and said pair of betatron oscillation inducing blades, wherein the circulating charged particle beam comprises a radius of curvature passing through said betatron oscillation blades, and wherein the reduced energy charged particle beam, resulting from transmission through said extraction material, comprises a radius of curvature passing through said extraction blades.
