Collection of separated isotopes for radioactive target production at RIA Original Research Article

The Rare Isotope Accelerator (RIA) is designed to deliver unprecedented intensities and a wide variety of radioactive beams. There is interest in collecting many of the highest intensity, long-lived (t1/2≳1 day) mass- and recoil-separated beams for the production of radioactive targets or for applications where high specific activity sources are needed. Based on an intensity of ≳1011/s, collection rates of ∼ 2 μg/day or more are possible. Herein, we consider the primary or parasitic collection of mass-separated beams on either the ISOL mass separator or the recoil separator. Once the desired activity is collected, it may be used directly as a target or will be moved to a hot cell for radiochemical purification and target preparation. A concept for the collection and preparation of radioactive samples is outlined.
