Abstract: Provided herein are approaches for improving ion beam extraction stability and ion beam current for an ion extraction system. In one approach, a source housing assembly may include a source housing surrounding an ion source including an arc chamber, the source housing having an extraction aperture plate mounted at a proximal end thereof. The source housing assembly further includes a vacuum liner disposed within an interior of the source housing to form a barrier around a set of vacuum pumping apertures. As configured, openings in the source housing assembly, other than an opening in the extraction aperture plate, are enclosed by the extraction aperture plate and the vacuum liner, thus ensuring appendix arcs or extraneous ions produced outside the arc chamber remain within the source housing. Just those ions produced within the arc chamber exit the source housing through the opening of the extraction aperture plate.

Abstract: The invention comprises a tandem accelerator method and apparatus, which is part of an ion beam injection system used in conjunction with multi-axis charged particle radiation therapy of cancerous tumors. The negative ion beam source includes an injection system vacuum system and a synchrotron vacuum system separated by a foil, where negative ions are converted to positive ions. The foil is sealed to the edges of the vacuum tube providing for a higher partial pressure in the injection system vacuum chamber and a lower pressure in the synchrotron vacuum system. Having the foil physically separating the vacuum chamber into two pressure regions allows for fewer and/or smaller pumps to maintain the lower pressure system in the synchrotron as the inlet hydrogen gas is extracted in a separate contained and isolated space by the injection partial vacuum system.

Abstract: The invention comprises a negative ion beam source vacuum method and apparatus used as part of an ion beam injection system, which is used in conjunction with multi-axis charged particle or proton beam radiation therapy of cancerous tumors. The negative ion beam source contains a vacuum chamber isolated by a vacuum barrier from the vacuum tube of the synchrotron. The negative ion beam source vacuum system preferably includes: a first pump turbo molecular pump, a large holding volume, and a semi-continuously operating pump. By only pumping ion beam source vacuum chamber and by only semi-continuously operating the ion beam source vacuum based on sensor readings about the holding volume, the lifetime of the semi-continuously operating pump is extended.

Abstract: A particle source in which energy selection occurs by sending a beam of electrically charged particles eccentrically through a lens so that energy dispersion will occur in an image formed by the lens. By projecting this image onto a slit in an energy selecting diaphragm, it is possible to allow only particles in a limited portion of the energy spectrum to pass. Consequently, the passed beam will have a reduced energy spread. The energy dispersed spot is imaged on the slit by a deflector. When positioning the energy dispersed spot on the slit, central beam is deflected from the axis to such an extent that it is stopped by the energy selecting diaphragm. Hereby reflections and contamination resulting from this beam in the region after the diaphragm are avoided. Also electron-electron interaction resulting from the electrons from the central beam interacting with the energy filtered beam in the area of deflector is avoided.
