Abstract
A new spherical grating undulator beamline has been commissioned at the synchrotron radiation source ASTRID in Aarhus. It covers an energy range from 12 to 130 eV with a resolving power of about 15.000. This beamline is combined with an end-station for angle-resolved photoemission. The spectrometer is a 75 mm mean radius hemispherical electron energy analyzer which is mounted on a goniometer within the ultra-high vacuum chamber. The motions of the analyzer and several settings of the beamline are motorized and computerized scans can be performed. The system is in particular well suited for measurements of the electronic structure along arbitrary lines in k→||-space, Fermi surface mapping and studying the polarization dependence of photoemission features.
