20. Scan TABLEHORZ motor while looking at I0 signal. Scan +/- 3 mm, with 0.3 mm point spacing. After scan, click on the maximum of I0 and move TABLEHORZ motor to this position.
21. Move MONO to desired edge energy.above and below the edge energy and make sure that your signal is within a range of 0.3 and 4 V. If not, adjust the gains in xasutils → ion chambers.
22. If you adjust gains, remember to close beam and check offsets.
2322. To run a calibration scan, in the XAS Data Collector → Regions panel, select a calibration region file from the pull-down list, or create a new one in using Region → "Region Wizard" (this will open up a new tab) indicating the desired absorption edge, and "Foil" for an abbreviated edge region. Save and return to the main Data Collector window.
2324. Create a single lined queue in the Queue Manager panel. Change the experiment line to use the detector file, region file, and number of sweeps (1) that you want to run.
2425. Run calibration region file. Open the plotter and plot current.
1526. Plot log(I1/I2) versus energy, or if using scattering photodiode, create a custom plot of log(I0/I2) versus energy with denominator 1. After the scan, select the Math tab and plot the first derivative. Find the position of the first maximum of the derivative (the inflection point of the regular absorption data).
1627. Move MONO to energy of first derivative maximum.
1728. Calibrate energy to desired edge energy in X-ray Data Booklet using Calibrate -> Calibrate MONO in XAS Data Collector → MONO
1829. Select new SCA fluorescence windows in WebGe window. Remember to "Update DXPs" when you're done, and Save SCA file with name of new absorption edge.
1930. Begin collecting data!
