instrumentation

 
 

Our research is mainly carried out at the electron storage ring ASTRID2 in Aarhus. We have built up the beamline SGM-3 which takes its light from ASTRID2's undulator. The experimental station is equipped with a spectrometer for angle-resolved photoemission (Specs Phoibos 150) and a sample manipulator with six degrees of freedom and cooling to a base temperature of 30 K. The set-up is further equipped with a preparation chamber, an MBE chamber and further analytical tools, such as STM and LEED. 

 



The figure below shows the surface state dispersion of Au(111) measured with the Specs Phoibos analyzer. In combination with the SGM-3 beamline, this analyzer permits measurements with excellent energy resolution (< 10 meV) and angular resolution (< 0.15 deg).
