Experimental Techniques 52 Figure 2.19: Optical layout of the WERA soft x-ray beam line, ANKA. 2 (vertical) to focus the incoming beam into the entrance slit of the grating box and also a pair of bendable focusing mirrors after the exit slit for optimum focus at sample position. Both entrance and exit slits are movable. The energy resolution ∆E/E < 10 −4 . The photon energy range is 100 - 1500 eV. The experimental facilities associated with the WERA soft x-ray beamline are PES, PEEM, NEXAFS and SXMCD. The BEAR beamline at ELETTRA is dedicated to the study of optical, electronic and magnetic properties of materials under UHV condition. The lay out of the BEAR beam line is shown in the Fig. 2.20. The beamline optics is based on a couple of parabolic mirrors. The radiation is collimated by the first parabolic mirror (P1). The parallel beam produced by P1 reaches the monochromator stage based on the plane grating/plane mirror scheme according with the Naletto-Tondelo scheme [53]. There are three gratings (G-NIM, G-1200 and G1800) associated with the monochromator. Three gratings cover 5 - 1600 eV photon energy range. The G-NIM (1200 1/mm) works at near normal incidence to cover the 5 - 45 eV region. The G1200 (1200 1/mm) and G1800 (1800 1/mm) work in the 45 - 1600 eV energy range. The monochromatic radiation is focused onto the exit slit by a second parabolic mirror (P2). The elliptical re-focusing mirror (REFO) brings the beam at the sample position. The experimental

The BACH beam line is designed to deliver a photon beam with high intensity and brilliance in the soft x-rays energy range 35 -1600 eV with full control of the polarization of the light. The goal of this beam line is to perform the electron and photon spectroscopy experiment with polarization dependence. The optical layout of the BACH beam line [54, 55] is shown in the Fig. 2.21.
