| Abstract | We report on recent progress in the evaluation and reduction of the systematic shifts of the strontium ion clock, addressing effects such as the collisional frequency shift, the servo tracking errors, and the blackbody radiation (BBR) shift. The total uncertainty is currently dominated by the BBR field evaluation. All the other known contributions are at least one order of magnitude smaller. Experiments are underway to improve the BBR field evaluation using thermal imaging of a dummy ion trap. |
