Traveling-wave deceleration of SrF moleules — •Sreekanth Mathavan, Joost van den Berg, Corine Meinema, Artem Zapara, Klaus Jungmann, Ronnie Hoekstra, and Steven Hoekstra — University of Groningen, The Netherlands

We work on the development of methods to cool and trap selected diatomic molecules suited for precision measurements, exploiting the long coherence time offered by cold, trapped molecules.

Traditional stark decelerators are inefficient for the deceleration of heavy diatomics such as SrF, due to instabilities. We have built a traveling-wave decelerator in our lab for the deceleration of heavy diatomics, which is inherently stable. We are improving the molecular source in order to achieve optimal rotational cooling and molecular density. Following the deceleration, we will laser cool the molecules to prepare them for a parity violation measurement.

We present the status of the experiment and present the first results on the deceleration of SrF molecules in a traveling-wave decelerator
