Abstract:
Beryllium-7 (7Be) was created by proton irradiation of natural (natB) and enriched (10B) boron targets. The targets were dissolved in nitric acid, and the 7Be was separated from the bulk boron target material by cation-exchange chromatography. An average recovery of (99.4 ± 3.7)% was obtained for 6 separations. The purified 7Be sample was placed into a batch-mode ion source to create a 7Be beam that was delivered at an average rate of 5 × 105 pps to end users at the National Superconducting Cyclotron Laboratory.
