We present an experimental setup for the preparation and detection of Rydberg states with chiral properties [1] using a novel excitation scheme. We have achieved the loading of Rubidium atoms from a MOT to a crossed dipole trap, to carry out subsequent two-photon excitation into Rydberg states. The dipole trap has been characterized in terms of atom number and temperature using absorption imaging. Subsequently, a superposition of circular states can be generated to realize Rydberg wave functions with chiral signatures. The design of a field ionization setup for state selective detection is presented.
