Some aspects of the design and usage of vacuum ultra violet beam lines are discussed. Fermat's principle for imaging is introduced and applied to grating monochromators. Some typical vacuum ultraviolet beam lines are presented, and some further topics believed to be of importance today and in the future are mentioned.

We present combined first-principle calculations and experimental results of the transversal magneto-optical Kerr effect (T-MOKE) of thin Fe films across the 3p edges using linearly polarized synchrotron radiation. We show that the experimental T-MOKE spectra at the 3p edges of Fe exhibit clear signals that are strongly influenced by interference effects. Ab initio calculated T-MOKE asymmetry spectra confirm the importance of interference effects. The comparison of experimental with calculated spectra reveals some differences that we attribute to metal/metal interface roughness that is not taken into account in the calculations.
