Progress Towards Intra-Cavity Enhancement Cooling Ca⁺ in a Compact Penning Trap

Cold, trapped atomic ions are of interest for experiments in quantum simulation, sensing and metrology, and quantum information science. Compact Penning traps facilitate the generation of 2-D ion crystals through a combination of permanent magnet geometries and static electric fields. In addition to magnet geometry, additional design improvements can be made to optimize trap characteristics. Our novel trap design incorporates temperature-stable permanent magnets, interchangeable PCB electrodes, an in-vacuum optical cavity for all-infrared laser cooling enhancement and laser ablation loading. We present results on characterizing laser ablation loading and all-infrared cooling Ca⁺. We also discuss future steps to introduce ⁴³Ca⁺ and ⁴⁴Ca⁺ co-confinement for progress towards dual-species high-field atomic clock transitions.
