Observed image of the focused beam at 1.38 Å. From lower to upper, was rotated from 118.0°, where the surface of the monochromator is almost flat, to 56.0° in 10.3° steps. Since 6 mm of aluminium plate was used as an attenuator, mainly the higher order harmonics of 1.38 Å are recorded on the imaging plate. The imaging plate was moved 3 mm vertically between each exposure to record all images on one plate without overlap. |
