Abstract

The success of many experiments at rare-isotope facilities, such as the National Superconducting Cyclotron Laboratory (NSCL), depends on achieving a level of statistics that is partly driven by the overall number of nuclei produced in the beam. One such future study at the NSCL requires maximizing the beam content of 34mCl. To prepare for this 34mCl study, an initial measurement to determine the 34mCl yields and overall beam purity was performed at the NSCL by utilizing a Beta-decay experimental station. Isotopes delivered to the experimental station were identified using standard time of flight and energy loss techniques. To explore ways of maximizing 34mCl production, 6 different beam energy settings that selected different rigidities for isotopic selection and altered its entrance angles before the beam went into the fragment separator, were utilized. The absolute intensity of the peak energies associated with the decay of 34mCl (1177, 2127, and 3304 keV) were determined, as well as the overall number of 34Cl atoms delivered, thereby enabling 34mCl yield and beam purity determinations for each beam setting.
