| Abstract Scope |
Californium-249/250/251 (mixed) targets are one option for continued work on the study and discovery of superheavy elements. Previously, mixed 249/250/251Cf material was recovered and purified from decayed 252Cf sources stored at Oak Ridge National Laboratory (ORNL). This purified material was electrodeposited onto thin titanium foils (1.5 μm thick) and assembled into target segments. In 2015, the targets were irradiated with a 48Ca beam at the Joint Institute for Nuclear Research. A decrease in the quality of the alpha spectra of the targets was noticed after several months of irradiation. Visual inspection showed that a film of unknown composition and origin had formed on significant portions of several target segments. The target segments were shipped back to ORNL for recovery of the californium material to produce new target segments. This presentation will address changes in the target production process to avoid the use of silicone gaskets in the final target segments. |
