A new apparatus for trapping single strontium atoms in arrays of optical microtrapsTobias Kree, •Felix Rönchen, Jonas Schmitz, and Michael Köhl — Physikalisches Institut Bonn

We present the design and implementation of the vacuum system featuring a custom designed titanium vacuum chamber with optical access along six different axes. The apparatus offers space to incorporate two high-NA objectives (NA > 0.65) to manipulate and read out atoms cooled to the motional ground state. One of the two objectives is characterized and currently being installed. In addition we describe the sequence of cooling steps we implemented to rapidly cool thermal Strontium atoms to microkelvin temperatures. To produce optical dipole traps we set up and characterized a liquid-crystal based spatial light modulator. We are able to produce highly uniform one-, two- and three-dimensional geometries of hundreds of optical foci. The system will be integrated into the main experiment in the upcoming months. In the future the experiment will be used as a quantum simulator profiting from the powerful combination of high imaging efficiency and arbitrary arrangements of single atoms.
