Doing Uniformity Measurement
- Stop beam.
- Open FS1_SEE:BGV_D2589, then remove the Faraday Cup.
- Insert Viewer D2569 on the FSEE GUI.
- On the viewer page, set the status to Live. Then start the chopper and put beam on the viewer.
- Select the cumulative average n value to begin accumulating points, up to about 10, then pause.
- Open the slice view tab under option.
- On the side, change evaluation parameter from X to rectangle. Drag the cursor on the viewport to place a rectangle onto where the beam is. This will give you the uniformity measurement.
- Then click the arrow button on the bottom right of the screen, which will update the uniformity for the users.
- Once this is done, go ahead and take out the viewer and put FC_D2569 back into the beamline.
- Put beam back onto the cup and wait a second. Then you'll click, on the bottom right corner of the FSEE GUI page, the Send flux o users / Calibrate Jaws button.
- Once this is done, stop beam and the uniformity measurement will be done.
