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.
