    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.
