This project will fabricate and characterize a high efficiency, high charge state, permanent magnet electron cyclotron resonance ion source. This ion source system will be used for the production of rare isotope ion beams and other heavy ion accelerators for nuclear science research supported by the Department of Energy. Phase I determined a set of optimum parameters for the ion source and developed a hot liner and a medium temperature oven for the production of solid isotopes. The engineering design and the cost estimates for the ion source system were completed. In the design, the ion source was placed at an adequate distance from the production target, through a thermal transfer line, to reduce radiation damage to the ion source magnets. Phase II will fabricate the permanent magnet electron cyclotron resonance ion source system designed in Phase I to demonstrate and characterize its high ionization efficiency and other capabilities. Tests will be conducted to determine the ability of the ion sources to produce intense intermediate and high charge state heavy ion beams in continuous and pulsed modes. The tests will be conducted at the Department of Energy's Argonne National Laboratory to demonstrate the high ion efficiencies of the ion source.
Commercial Applications and Other Benefits as described by the awardee: In addition to the applications in nuclear and atomic physics and applied science, the electron-cyclotron-resonance ion source should find application in industry for high energy ion implantation, ion milling, and surface modification.
