Ultracold dipolar molecules constitute a promising system for the investigation of topics like ultracold chemistry, novel interactions in quantum gases, precision measurement and quantum information.

Here we report on the construction of a versatile transport apparatus for the production of ultracold YbRb molecules. This setup constitutes an improvement of our old apparatus, where the interactions in YbRb and possible routes to molecule production have already been studied extensively [1,2]. In the new setup a major goal is the efficient production of ground state YbRb molecules.

Separate production chambers allow the parallel production of Yb and Rb samples. Optical tweezers transport both species to a separate science chamber. This chamber provides excellent optical access and room for additional components in- and outside of the vacuum.
