The I15-1 Sample Position
The sample position on I15-1 is defined in the images below. The y stage has a travel range of 500 mm, with ca. 170 mm below the beam position and ca. 330 mm above. The x stage has a travel range of ca. 125 mm. With the sample stage set to x = 0 (furthest back), there is a distance of 420 mm between the sample stage and the beamstop arm. The beamstop arm is located ca. 140 mm below the beam position. The images below depict a standard beamline setup, with a distance of ca. 260 mm between the clean-up and the detector. The beamstop is positioned ca. 100 mm from the detector. These dimensions are liable to change however, as the length of the clean-up, position of the detector and the position of the beamstop can be changed along the z-axis to optimise Qmin for a given experiment where necessary.
Mounting Brackets
| Section | |||||
|---|---|---|---|---|---|
This bracket mounts directly onto the Y stage. It is secured by M6 bolts onto the stage and is aligned on two dowel rods for reproducible alignment of the bracket with the stage. There is a slot cut into the surface which acts as a keyed edge for cells to be butted up against, to provide reproducible alignment of the cell with respect to the bracket. The cell should be attached by 3 x M6 bolts spaced 37 mm apart through the rear of the bracket in countersunk holes. The entire mounting bracket can be removed from the stage and reattached reproducibly. |

This bracket is mounted onto a Thorlabs breadboard that is attached to the Y stage. Cells should be attached onto this bracket using 4 x M5 bolts. There are 3 keyed edges for the cells to be aligned to, the corners of which have a radius profile, which makes mounting onto this bracket reproducible. The corners of the cut-out section have a radius profileThis bracket remains attached to the beamline whilst the cell can be removed and reattached to the bracket reproducibly. |
