Towards building and loading a Ioffe trap using a 2D MOT — •Benedikt Tscharn, Lukas Schumacher, Marcel Willig, Gregor Schwendler, and Randolf Pohl — Johannes Gutenberg-Universität Mainz, Institut für Physik, QUANTUM & Exzellenzcluster PRISMA+, Mainz, Germany

Unique information about atomic and nuclear structure of light atoms can be determined by precision laser spectroscopy and provide information about fundamental constants, interactions and properties [1]. We plan to build an apparatus for high-precision laser spectroscopy of ultracold ⁶Li at 670 nm in a magnetic Ioffe trap.

Only very slow atoms can be captured inside the Ioffe trap. Therefore, a 2D magneto-optical trap using permanent magnets was built that is used to precool hot lithium vapour which is subsequently transported into the Ioffe trap using a push laser beam [2].

In this contribution we provide an overview about the setup of the 2D MOT, the lasers and the cold lithium loading beam and give an outlook to the magnetic trap.
