Therefore a much higher accuracy of beam profile measurement than actually achievable by the current wire scanner is required. The new performance demands a wire travelling speed up to 20 m/s and a position measurement accuracy of the order of 1 µm. In order to minimize the error source of the wire position measurement, a challenging concept has been developed which consists of the placement of the motor rotor and the angular position sensor in vacuum. The implementation of this new concept requires the use of a magnetic brake, hybrid vacuum bearings, the design and production of very thin (<0.5mm) wall vacuum chamber regions and the production of titanium components by 3D additive technologies. The implementation of this new concept has required different optimization processes as the structural optimization under dynamic load of the most critical rotating elements or the optimization of the control system and the motion pattern. This contribution gives an overview of the new device design and shows the different technical solution applied to develop the new concept in a successful way.
