Introduction to I12 – JEEP

BEAMLINE OPERATION DURING ONGOING COVID-19 CONTROL MEASURES

Beamline I12 is currently operating at Level 3 (experiments run by staff on behalf of users. Limited staff presence to run experiments. No users on site. Strict social distancing and working protocols.)

After some trials, DLS is moving to Level 2. From October 2020, I12 will schedule cancelled AP27 experiments that are feasible under Level 2 conditions. (Limited staff presence on site, 1 or 2 users on the beamline. Strict social distancing and working protocols. Generally beam available from 09:00 Tuesday to 09:00 Saturday. Staff are not required to be on site at the weekend.)

Experiments which require operation at Level 1 (normal user operation) are unlikely to be scheduled, and Principal Investigators are encouraged to re-apply with a simplified experiment when the next call opens.

AP27 Principal Investigators have been contacted.

When a new call for proposals is made, experiments will be assessed for their feasibility at the expected operating Level. Please respect these points when writing your proposal:

We may be at Level 3 with no users allowed on site.
We may be at Level 2, with only 2 users at a time permitted on the beamline. This may be restricted to 2 users per experiment.
For Level 2, shift working will be considered, with a total of 4 users working in teams of 2 people.
Even with shift working, 24 hour operation may not be allowed, due to the risk of user and staff fatigue.
Social distancing and COVID-19 working protocols increase the length of time required to perform tasks.
Ensure that you will have samples and equipment ready for scheduling at short notice. It is not possible to accommodate user preferences for "good" and "bad" dates.
Beamline staff will not take responsibility for setting up or operating sample environments owned by users.
Complicated, ambitious experimental equipment setups are not encouraged until we are confident that Level 1, normal user operation is possible.
As always, please discuss the feasibility of your proposal with beamline staff before submisssion.

I12: Joint Engineering, Environmental, and Processing (JEEP)

Beamline I12-JEEP (Joint Engineering, Environmental, and Processing) is a high energy X-ray beamline for imaging, diffraction and scattering, which operates at energies of 53-150 keV.

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

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.

I12 can accommodate complex sample environments (chemical, mechanical and electrical processing equipment, engineering machinery, all kinds of experimental apparatuses), which the users can bring and install for their beamtime. We accommodate small and medium sized sample environments in EH1 and large ones in EH2.

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.

Recent Upgrades at Beamline I12:

Large Field of View Camera for tomography of large samples
Fast X-ray camera for monochromatic and white beam radiography and tomography
INSTRON 100 kN uniaxial mechanical test rig for in situ diffraction and imaging experiments and for ex situ sample preparation before measurements
