Abstract

Progress on the realization of an experimental setup for the simultaneous creation of quantum degenerate samples of fermionic ⁴⁰K and bosonic ⁸⁷Rb is presented. The apparatus is based on a double MOT design with a 2D source MOT and a 3D collection MOT both acting on both species. After laser cooling selective forced microwave evaporative cooling of ⁸⁷Rb on the hyperfine transition is planned in a magnetic Ioffe-Pritchard trap. The fermionic ⁴⁰K component will be sympathetically cooled by the rubidium atoms without additional loss of particles until quantum degeneracy is reached. A high number of fermions is expected by using isotope enriched ⁴⁰K dispensers for feeding the 2D source MOT.
