1. All fields above are required.
2. When mounting samples to the sample holder, make sure the "Source" side of the holder faces you. The spacing between neigbouring samples is 20mm(H) and 11mm(V).
3. In the below form, "Name" will be the data file name for the sample and should be ONE word, without special characters like "&", letters and numbers combination recommended.
4. "x" and "y" are position of the sample. The (0,0) position in magenta color is labeled on Sample#1 in the above figure. y=0 is set at 90mm from the reference hole. Positions below 0-position are in positive values, above 0 is negative.
5. "Exposure time" is the X-ray exposure time. Default value is "1", and can be determined later at beamline. It is a good idea to put a test sample at position#1 for this purpose.
6. "Sample Thickness" is required for absolute scattering intensity conversion, otherwise leaving as default "1".
7. "Description" contains information of the sample, including chemical composition. It's required for waste disposal purpose at APS.
8. After finishing the form, click "Submit" bottom at the top of the page to save.
