We report on the current status of our experiment employing a hybrid atom-ion trap for investigating the interaction between OH− anions and rubidium atoms. The experimental configuration consists of an octupole rf ion trap with thin wires. The design provides a large field-free center as well as sufficient optical access to combine the ion trap with a magneto optical trap (MOT) for the atoms. The MOT can be extended to a Dark Spontaneous Force Optical Trap.
