June 24th- Day 6

Spot on!

With the camera anyways. We put the camera in place and almost instantly were able to see the image we were looking for. We then hooked up the detector and were able to find the spot rather quickly. That's when things started taking a turn for the worse. One of the actuators stops working for us and it had to be replaced. We aligned the old actuator with the new one to minimize the scanning that would have to be done to align everything later on for finding the spot again. At first Alex gave us a Ni filter to use but then decided it would be more efficient to use a Cu filter instead. We then scanned in x, set the ROI values and scanned in y of the detector. Then to account for the backlash when scanning the source in x had to drag the cursor to the peak > set to start > go to start > set to zero > move the stage minus about 200 microns > go home. Then we scanned the source in y and did the same procedure for the backlash. After we put the knife edge back on and started scanning for the spot. After each scan in x and y of the detector we set to zero. Then we scanned  y and x of the source and followed the backlash procedure. After that was all set we started scanning for the spot size. The vertical spot size should change more drastically according to the results obtained by XOS that we were using as a reference. Before we could get very far... another actuator decided it wasn't going to move as far as it could and we had reached a 'hard limit.'
