Towards direct frequency comb spectroscopy on ions in a linear Paul trap

Abstract

In 1999, Webb et al. claimed a possible variation of the fine structure constant on cosmological time scales [1]. These results are based on a so-called many-multiplet method, comparing quasar lines from many atoms and ions with laboratory values. However, this claim has also been disputed (for example in [2]). Currently, many ionic lines that are interesting for this analysis are only known to a precision of a few tens of MHz. We plan to measure some of these ionic transitions to higher precision, enabling a more precise comparison. For this purpose, a multi-species linear Paul trap has been constructed.
