Set-up for SXES measurements as seen from above (y-direction of the manipulator). The photoelectrons emitted by the last refocusing mirror unit are detected as a direct measure of the synchrotron light intensity. In order to achieve optimal count rates the z-coordinate of the sample holder has to be carefully adjusted so that the synchrotron beam spot on the sample lies completely within the viewing angle of the spectrometer. |
