Experimental Techniques 54 Figure 2.22: The variable included angle monochromator : the combined movement of PM1 (plane mirror) and one of the four spherical gratings SG1(-4) leads to the monochromatization of the light keeping both the entrance and exit slit fixed. The radiation source is based on two APPLE-II elliptical undulators that are used alternatively to optimize the flux. The photon dispersion system is based on the Padmore ”variable angle spherical grating monochromator (VASGM)” scheme and it includes four different interchangeable spherical gratings (Fig. 2.22). The first three gratings works in the energy ranges 35 - 200 eV, 200 - 500 eV and 500 - 1600 eV respectively. The fourth grating operates in the 400 - 1600 eV range providing higher flux allowing fluorescence and x-ray scattering experiments. Two refocusing sections, based on plane elliptical mirrors in Kirkpatrick - Baez configuration provide nearly aberration free spots on the samples. A third branch line after the monochromator will host a microscope based on Fresnel zone plate focusing. The following experimental facilities are associated with the BACH beam line ; XPS, UPS, XAS, XMCD, XMLD, SXES and RIXS.
