Intensity distribution around the sample position of the SCS instrument. Left panel (a), (c): the clean-up slits in the vertical and horizontal focus are fully open. Right panel (b), (d): both clean-up slits are closed to a gap of 50 µm. The cuts perpendicular to the optical axis in (c) and (d) correspond to −6, 0 and 6 mm positions around the focus. |
