Measurement station thanks to Technische Universität Dresden (TU Dresden) and Freie Universität Berlin

A new instrument became available to the users of BESSY II in October. The new beamline and apparatus for spin- and angular-resolved photoemission in the Russian-German Laboratory at BESSY II have successfully completed their test phase. They facilitate precise measurements of the electron band structure and spin of different material classes such as topological insulators and magnetic sandwich structures, as well as novel perovskite-based solar-cell materials. A photoelectron microscope has also been developed which is particularly important for nanoscopic structures.
The Russian-German Laboratory has existed at BESSY II for more than fifteen years, operating its own beamline for absorption and photoelectron spectroscopy. Now, in addition to the dipole beamline, lab members have also set up a powerful measurement station for spin- and angularly-resolved photoelectron spectroscopy and photoelectron microscopy on an undulator beamline. This measurement station was developed together with Technische Universität Dresden (TU Dresden) and Freie Universität Berlin through a German Federal Ministry of Education and Research (BMBF) grant. The measurement station along with Russian and German user-support teams will be available beginning at the next beamtime period.
