Description

The Brunner group at McGill University has developed a laser ablation ion source in ultra-high vacuum followed by a mass filter, and is exploring the feasibility of using these to load radioactive Be-7 ions onto quantum sensors for use in the BeEST experiment. This work aims to expand the existing mass range of the setup to demonstrate that the instrument can be used to ablate, filter, and implant Li-7 ions (as a mass equivalent surrogate for Be-7). Details on the electronics upgrade and mass filter performance will be presented using results from a thermosilicate mixed alkali source.
