Figure 8
Reflected intensity of two Brewster-angle multilayer mirrors (Cr/Sc and Cr/C) as a function of azimuthal angle to determine the linear polarization of the beam at two energies (134 eV and 341 eV, respectively). The beamline vertical opening angle was set differently (0.6 and 0.15 mrad, respectively) and thus the net linear polarization. Multilayer parameters, blue curve: Cr/C with 40 periods and a period thickness of 6.64 nm operated at a Brewster angle of 45°; red curve: Cr/Sc with 400 periods and a period thickness of 2.57 nm operated at a Brewster angle of 45° |
