      abstract     = {A design for a manipulator system for manipulating bare
                      scanning tunneling microscopy (STM) tips without any tip
                      holder is presented. The extremely stiff and rigid system
                      consists of an ultrahigh vacuum compatible fully
                      three-dimensionally movable gripper module driven by
                      stepping motors and piezomotors. The tips are clamped by
                      hardened tool steel gripper jaws, which are controlled by a
                      stepping motor through levers. The system allows the
                      reproducible manipulation of bare tungsten tips made of
                      wires with diameters of 0.25 nm and having length of only up
                      to 3 mm without damaging the tip or the STM. The tip
                      manipulators' advantage is that the total mass of the
                      scanning piezotube is reduced by removing the mass of a
                      separate tip holder. Thereby, it becomes possible to further
                      increase the resonance frequencies of the STM.},
