As proof of performance and as part of the characterization of their new DA30-L and VUV5k ARPES system the Prof Bing Wang group of University of Science and Technology of China have measured a Au(111) sample. The data shows a well resolved surface Shockley state with the characteristic spin split parabola. Using the DA30-L deflection mode a full data set was acquired without rotation of the sample. This is illustrated by the graph showing a series of parallel kx-ky cuts in momentum space.
