  • Thermal cycle recirculating pump for isotope purifier
    Patent number: 4758721
    Abstract: A magnetic mass spectrometer used to purify ions in a polyisotopic mixture wherein non-ionized particles which exit the ion source are collected in the vacuum chamber and are then introduced into a thermal cycle pump and returned to the ion source to increase the yield. This purifier will both separate a desired isotope, such as iodine-123, from the polyisotopic mixture produced by a conventional small cyclotron, and increase the recovery rate, thus making feasible its use in nuclear medicine.
