Sammendrag
The design of a 5-axis manipulator for use in Angle-Resolved Photoemission Spectroscopy (ARPES) is presented along with an outline of the specific challenges it was designed to adress. The theory and nomenclature of X-ray Photoemission Spectroscopy and ARPES is reviewed. The lab at the Norwegian University for Science and Technology and its Ultra-High Vacuum chamber to be upgraded is introduced. Further upgrades to the detector and the purchase of a new X-ray gun is discussed, along with the possibility of utilizing oxygen K$_\alpha$ radiation from oxidization of the magnesium anode in the X-ray gun currently in use. To optimize results from this method, the anode voltage for maximum radiation intensity from the O K$_\alpha$ was determined to be 8 kV. Time constraints prevented proper testing and implementation of the finished manipulator.
