TSCAC Two-species composite atomic clocks

This project will explore new techniques and methods to provide novel primary measurement standards for time and frequency. While today’s best optical clocks rely on the use of a single atomic reference transition, this project will investigate two-species composite atomic clocks that improve in terms of accuracy and frequency instability. The project fosters collaboration between leading scientists in the field with complementary expertise from NMIs, universities and research institutes. Besides work towards composite clocks based on established atomic clock species, new reference transitions will be explored in highly charged ions and initial spectroscopy of the low-energy 229Th nuclear transition prepared.
