Project Details
Description
Supporting the use of multi-species atomic clocks as future SI standards
Clocks and frequency standards are the most precise measurement devices available. While today’s best optical clocks rely on the use of a single atomic reference transition, two-species composite atomic clocks promise to achieve even better performance.
Project will focus on metrology research necessary to support the use of multi-species atomic clocks as future SI standards.
VTT MIKES investigates novel interrogation sequences for two-species, ion-based optical clocks, measures frequency shifts induced by laser radiation and assesses DC and AC Zeeman effects in single ion traps.

This project has received funding from the EMPIR programme co-financed by the Participating States and from the European Union’s Horizon 2020 research and innovation programme.
