Experimental set-up. Synchrotron radiation is generated by a 5 m APPLE-II type undulator and is transmitted through the beamline including a beam-defining slit, monochromator comprised of a VLS plane grating and pair of plane mirrors, exit slit, focusing mirror and collimating mirror. The beam is focused on the apertures by the focusing mirror and forms a diffraction pattern on the CCD detector positioned in the far-field. The horizontal plane mirror and the collimating mirror are not shown in the figure. |
