Abstract

We report the trapping and laser cooling of Ca+ in a linear Paul trap connected to an ICP-MS as an ion source. The ICP-MS enables the stable and efficient loading of Ca+ into the trap from outside of the vacuum chamber. The trapped ions are laser-cooled and their laser induced fluorescence (LIF) is observed. The odd isotope 43Ca+ and the least abundant isotope 46Ca+ are trapped and laser-cooled successfully without the use of isotopically enriched samples.
