Sample Table 1 (ST1)

1. Technical description of Sample Table 1

Sample Table 1 can accommodate a variety of different samples and sample environments. In full configuration, it can accommodate weight of 50 kg, allowing diffraction, radiography, and tomography experiments. Removing the top tomography stage of Sample Table 1 permits accommodation of samples and sample environments with a weight up to 200 kg and allows diffraction and radiography experiments only.

Sample Table 1 has up to 10 degrees of freedom of motion, and different combinations of motion can be set up. During tomography experiments, some axes are needed to align the sample table and to carry out automated motions. Then, these axes are not available for other purposes and thus the number of degrees of freedom to the sample is limited.

Sample Table 1 can also be considered as a motorised goniometer allowing rotation of the sample along three Eulerian angles. This facilitates single crystal diffraction at beamline I12.

2. Experimental arrangement of Sample Table 1

Please, consider making support plate of your equipment comparable with I12 Sample Table interface to avoid mounting problems during installation of your equipment:

- If Tomography module remains on the Sample Table 1 (configurations 1-4 on the scheme below), please use the drawing of Tomography module plate.

- If Tomography module is removed from the Sample Table 1 (configurations 5-8 on the scheme below), please use the drawing of interface plate.

Possible configurations of Sample Table in EH1 with distances (in mm) from top interface plate to white and monochromatic beam. Your sample need to have a height between presented values for exposing by X-rays. Sample > 50 kg will not have top translation or rotation available.

The heavy-duty Blue Frame can be placed around the Sample Table in EH 1 to accommodate the user’s the equipment which is heavier than 50 kg and allow tomo-stage to remain installed. When Blue Frame is installed around the Sample Table 1, only configurations 2 (tomo-stage + Y3 + Y1), 3 (tomo-stage + Y2 + Y1), and 4 (tomo-stage + Y1) are allowed, while configuration 1 is not permitted due to height limitations. The heavy user’s equipment can be installed on the Blue Frame and remain stationary, while sample can be installed on the rotation tomo-stage for tomography and/or diffraction measurements.

Download schematic of the heavy-duty Blue Frame or corresponding STEP-file in zip-achive.

View of the heavy-duty Blue Frame around the Sample Table in EH1 from the side and example of installation of user's equipment on the Blue Frame. Sample Table 1 has configuration 2 (tomo-stage + Y3 + Y1).

Sample Table 1 can be considered as a goniometer of a diffractometer, allowing rotation of sample along three Eulerian angles, making possible single crystal diffraction at beamline I12.

Single crystal diffraction using Sample Table 1. The relation to the traditional single crystal diffractometer is given on the right side (in analogy with Kappa-geometry). Combination of X- and Z-translations of the sample table corresponds to the X- and Z-translations for fine adjustment of goniometer head (usually manual); rotation angle θ of the sample table corresponds to the rotation angle φ of the single crystal goniometer; combination of X- and Z-tilts of the sample table corresponds to the angle κ of the single crystal goniometer; rotation angle Phi of the sample table corresponds to the rotation angle ω of the single crystal goniometer.

Additional space is available in close proximity to the Sample Table 1. This space is allocated for the positioning of user equipment that needs connection to the sample environment, e.g. rig controllers, computers etc. 

Additional space is available in close proximity to the Sample Table 1. Location of standard UK 13A single power socket, high current 32 A single power socket, and cooling water supply for user equipment (cooling water supply will be removed if users do not need it) is shown. Path to Search Button should remain free.

Large Detector Table 1 (LDT1)

The EH1 Large Detector Table (LDT1) is designed to take different detectors at the same time, each placed on a separate table module. Each module can be moved into beam position by traversing the whole table along the x-direction across the beam. This arrangement allows various detectors to be used during one experiment. As an example, one can perform a tomography experiment with the imaging cameras to determine the sample structure and subsequently investigate the stress state with the 2D area diffraction detector.

Large Detector Table 1 (LDT1) showing all 4 modules and various detectors: Module 1 with imaging camera, Module 2 with 2D Area Diffraction Detector, Module 3 (empty), Module 4 with Beamstop. Sample Table is shown in front of Large Detector Table 1. Coordinate system is shown for available movement of different modules of LDT 1 (see table below).

Small Detector Table 1 (SDT1)

The Small Detector Table 1 is located at the back of the EH1 at a distance 4500 mm from the sample table, and can be moved through the hutch perpendicular to the beam direction up to an angle of max. 15^o (in respect to the incident beam and the sample position). This allows to carry out diffraction and wide angle scattering experiments with the 2D area diffraction detector. With the table at 0^o it can be used for small-angle scattering for particles of size below 12 nm.

Optics Table, Anti-Scatter Guard, and Anti-Scatter Slits (S3 slits)

Optics table, anti-scatter guard, and anti-scatter S3 slits in EH1 in regards to Sample Table 1 with coordinate system.

The beam entry has two windows: for monochromatic beam (upper window) and for white beam (lower window). Switching between monochromatic and white beam takes ca. 30 min.

The alignment laser allows to approximate sample and detector alignment.

The Optics table can accommodate additional equipment, which can be moved into the beam. Available motions of optics table are: x-translation: +/-150 mm; y-translation: +/-50 mm; z-translation: +/-50 mm.

Remotely controlled anti-scatter S3 slits (with variable size and positon) can be used. The rectangular size of these slits can be varied in both directions from 0.05 mm to 10 mm (remote control of slits’ size is important for combined tomography/diffraction experiment).

Cooling water supply for user sample environment is available upon request. User equipment can be connected to a beamline heat exchanger. Ensure that your cooling circuit is clean!

Cooling water supply. Left: cooler with tubes. Right: Detail picture of tube connections. The flow direction is indicated by red arrows. Your equipment should have suitable connectors as described in the table above.

3. Pressurised gases

4. Transportation and lifting equipment

Help with transportation of large equipment can be given by prior arrangement. All equipment should be delivered on a standard EUR-pallet.

Inside the Experimental Hutch, a crane can be used for lifting equipment. The beamline 1 tonne crane must only be operated by beamline staff.

 Examples of lifting points and lifting eyes, attached to equipment, which users must provide to make possible the lifting of their equipment with a beamline crane.

The “crane hook-to-floor” height is approx. 2600 mm.

Depending on the configuration of Sample Table 1 used in experiment, the maximal height of your equipment, which is possible to move on Sample Table 1 by crane, will be different.

 Trolley for lifting equipment out of users' car. Please, ensure the correct orientation of the pallet with your equipment in the car.

5. User chicanes for cable access between Control Room and Experimental Hutch

6. Exhaust system

Experimental Hutch 1 has installed an exhaust system with a maximal flow rate of 5.7 m/s = 44.7 l/s in a single 100 mm diameter duct. The exhaust system can be installed above or close to Sample Table 1. Please, contact your local contact or Beamline Staff if you need to use an exhaust system.
