New Setup!
Alex showed us the new setup and told us all about it. This new crystal was Si (220) and had a Bragg angle of 1.06 degrees. The IFD is 75mm and the OFD is 328mm. This setup has a fixed source instead of a fixed optic, so the crystal can be moved in the x, y, and z axis as well ab rotated and tilted. The detector is the same as our previous setup having mobility in the x, y, and z axis. We used a shadobox (1024) camera to view the image of the optic. The camera was placed close to the optic and we would be using it to not only make sure the optic was aligned but to find the focal point as well. Most of the day was trying to find the focal point. Once we found a good spot size, we then had to move the z axis to try to further decrease the spot size. However, the FWHM the camera gave us is not the actual spot size.
