TRIX: Trapped Radium Ion eXperiments

The single trapped radium ion group is a recently started research project at the Accelerator Institute (KVI) of the University of Groningen (RUG), as a collaboration between TRIµP and the theory group. The TRIµP (Trapped Radioactive Isotopes: μicro-laboratories of fundamental Physics) program is concerned with low-energy tests of the Standard Model, in particular the search for violation of parity and time-reversal symmetries. The goal of TRIX is to find a low-energy value of the Weinberg angle, as a check of the value predicted by the Standard Model. This will be done by measuring atomic parity violation (APV) in a single trapped radium ion. As a possible spin-off we investigate the possibility of using radium as a new frequency standard, or atomic clock.

This project is funded by FOM, Rijksuniversiteit Groningen and NWO.
