Description
This paper review solid beam operations from the Superconducting ECR ion source at the Facility for Rare Isotope Beams (FRIB) at Michigan State University. FRIB delivers beams for nuclear physics experiment after acceleration through a superconducting linac. The current beam list is composed of 25 different isotopes out of which two third are solid elements. This list will continue to expand over the next few years to reach over 30 isotopes. Three types of oven are used at FRIB for the production of vapor depending on the temperature needed to reach a vapor pressure typically in the 1-10 mTorr range. A cartridge-based oven is used in the lower temperature range up to 600 ⁰C suitable for element such as Zinc, Selenium or Calcium. A new version is in development to extend operation of this design to approximately 800 ⁰C that we intend to use for the production of Molybdenum from Molybdenum Trioxide. A simple resistive oven is used to cover the range of 800 ⁰C to 1200 ⁰C which works well for Lead, Bismuth, Samarium or Silicon while an inductive oven is used up to 2000 ⁰C primarily used for Uranium production from uranium oxide but also used for Nickel, Germanium and Platinum. This paper review the operations of these oven as well as performances and efficiencies achieved for the solid beams.
