Title:     Developments for molecular and actinide ion beams at CERN-ISOLDE

Abstract: The ISOLDE facility at CERN provides experiments with a wide range of isotopes across the nuclear chart, produced in reactions from 1.4 GeV protons with thick targets and delivered as charged atomic ions or molecular species. Forming and extracting volatile molecules has been used to extract otherwise refractory species. Molecules provide opportunities to search for fundamental symmetry violations and contribute to the development of new physics beyond the standard model. Recent studies of radium fluoride at ISOLDE demonstrate experimental capabilities to study beams of radioactive molecules produced at radioactive ion beam facilities. The development of molecular beams is motivated by beam extraction, purity, and physics opportunities presented by radioactive molecules.

We present the first results of ongoing work on molecular ion beams of heavy elements at ISOLDE. Uranium carbide targets were used to produce molecular beams via injection of reactive tetrafluoro methane (CF4) gas. The ion beam composition was studied using: the ISOLTRAP Multi-Reflection Time-of-Flight Mass Spectrometer (MR-ToF MS) for identification by ToF mass measurements, online gamma-ray spectroscopy at the ISOLDE tape station, and off-line alpha- and gamma-ray spectrometry of ion-implanted samples. The results contribute to beam developments for actinide elements and radioactive molecules for fundamental physics research.
