Loading methods involving metallic barium, such as conventional electric ovens, are inappropriate for use with 133Ba+. Its radioactive nature limits the maximum sample size, increasing its surface-to-mass ratio and speeding up the oxidation rate. Here we present our work towards loading 133Ba+ by ablating barium salt targets. To build isotopically pure crystals, we load and then confirm the species of each ion before merging into a storage zone.
