"Ultra precision machining using atomic particle beams (UAT)"
Research programme funded by the BMBF (German Ministry of Education and Research) to improve collaboration between research institutions and local industry.
The research group focuses on researching and developing non-conventional methods for ultra-precision surface machining and shaping. Ion Beam Figuring (IBF) and Atmospheric Reactive Plasma Jet Machining (PJM) techniques are mainly used.

The properties of modern products are more and more determined by shape accuracy, structure, as well as functionality of its surfaces. Thus, the surface quality requirements are being tightened steadily. Surfaces exhibiting extraordinary shape are strongly demanded from different branches of industry. Examples of products with ultra-precision surfaces are optical elements like lenses and mirrors, or precision mechanical parts. Those products are applied in high-tech sectors like semiconductor industry or for scientific instrumentation (space applications, synchrotron radiation, etc.).
The increasing demands with respect to precision call for surface machining technologies which take effect on the atomic scale.
Ultra precision machining of surfaces using atomic particle beams is a section of nanotechnology. In order to fabricate exact surfaces shapes and structures with depth accuracies in the range of Ångströms we utilize reactive plasma jets and ion beams.
The surface area to be machined might be extended from square millimeters up to a few square meters. Surfaces shapes can be planar, convex, concave, or free form.
The project will strengthen the position of the regional centre of science and research, especially in the field of ultra precision machining, with respect to the global competitions for the future.
