New instrument at BESSY II commences user operation

Instrument developed by the Russian-German Laboratory at the Helmholtz-Zentrum Berlin. No 318/2019 from Oct 29, 2019 A new instrument became available to the users of BESSY II on Oct. The new beamline and apparatus for spinand 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 spinand angularly-resolved photoelectron spectroscopy and photoelectron microscopy on an undulator beamline.
