I12 was built to be suitable for experiments, which utilize:
- high-energy X-rays
- time-resolved in situ measurements
- monochromatic or polychromatic (“white beam”) X-rays
- imaging and diffraction techniques, including their combination during one experiment
- beam size up to 100 mm × 30 mm, both monochromatic and polychromatic
- complex sample environments provided by users (users are welcome to bring their own sample environment for diffraction and imaging experiments)
At I12 you can perform a range of experimental techniques:
- Static and time-resolved radiography and tomography
- Static and time-resolved powder diffraction using monochromatic radiation
- Time-resolved powder diffraction using energy-dispersive radiation
- Diffuse scattering on crystalline (single-crystal diffuse scattering) or amorphous materials (pair-distribution function analysis "PDF”)
- High energy X-ray small angle scattering
- High energy Laue diffraction using polychromatic radiation
General: All techniques use high-energy X-rays able to penetrate large samples or sample environments. Therefore sample preparation is simple and processes can often be studied under real-world conditions. For very high resolution in real space (< 2 µm) or in reciprocal space, lower X-ray energy techniques on other beamlines are more suitable.
The beamline has two in-line experimental hutches:
Experimental Hutch One (EH1) is inside the Diamond Experimental Hall. It provides a high intensity X-ray beam at a distance of around 50m from the x-ray source. EH1 is configured for experiments with small- and medium-sized samples and sample environments. A core feature is a sample table which can be configured to suit different sizes of experimental equipment and can be used for all available experimental techniques.
Experimental Hutch Two (EH2) is in an external building outside the Experimental Hall, which is in-line with EH1. It provides a space for large or complex experiments in physics, material science, geology, engineering and processing. Equipment setup and preparation for an experiment in EH2 can be carried out without interrupting ongoing experiments in EH1, allowing longer setup times of user-provided equipment.
