Recently, a new coating facility for the production of ultracold neutron guides started its operation at the Physics Institute University Mainz. With the use of magnetron sputtering it is possible to coat inner surfaces of glass tubes with diameters down to 50mm and a maximal length of 1.5m. By optimizing the coating parameters and due to the low surface roughness we expect higher transmission of ultracold neutrons compared to the so far existing polished stainless steel tubes. This talk will give an overview about the facility, its possibilities and first results of transmission measurements performed at the Ultracold Neutron facility at the TRIGA Mainz.
