Beamline Layout

Hutches at IBL

Hutches and other components of the IBL (P05). The X-ray beam travels from left to right in this picture. OH is the optics hutch, EH1 is the first experimental hutch and EH2 is the second experimental hutch.

Optics Hutch

The Imaging Beamline is divided in three parts: the optics hutch, experimental hutch 1 (EH1) and experimental hutch 2 (EH2). The whole beamline is operated by the Helmholtz Centre Geesthacht (HZG). The experimental hutches use the same monochromated synchrotron beam and therefore can only be run at different times. The experiments are controlled from a common control hutch.

Beamline Optics

The main components inside the optics hutch are two liquid nitrogen cooled, fixed exit monochromators. A double crystal monochromator (DCM) equipped with silicon
single crystals (111 and 311) designed by DESY, is used for tomographic methods which need a very high monochromatization (ΔE/E ≈ 10−4, e.g. absorption edge tomography, vector tomography). For applications which need particularly high flux (e.g. fast in situ experiments) a double multilayer monochromator equipped with different flat and bent substrates is currently under construction (ΔE/E up to 10−2).

Experimental Hutch 1 (Nano Tomography)

The nanotomography endstation in the experimental hutch 1, designed to allow 3D resolutions of below 100 nm, is currently under construction. As X-ray optics we will use compound refractive lenses (CRLs), made from SU-8 polymer using the LIGA process at the Institute for Microstructure Technology at the KIT, Karlsruhe.

Experimental Hutch 2 (Micro Tomography)

The micro tomography hutch is positioned at the second experimental hutch in a distance from source from 80 to 87.5 m. At this distance, the horizontal full width at half maximum of the beam is 5.6 mm which is sufficient to investigate millimeter sized samples with a spatial resolution down to the (sub)-micrometer range.
