  • Run the default queue with a region made for calibration scan at that edge. If you do not have one, you can use the "Region Wizard" to create a "Foil" region.
  • If running at low energy with calibration foil or compound on the motorized CALVERT holder, set CALVERT to its IN value (about 37.5)
  • Open plotter
  • Plot different quantities depending on calibration detection technique:
    • If foil in front of I2 back ion chamber, plot log(I1/I2)
    • If foil in scatter reference in front of I0 ion chamber, plot log(I0/I2)
    • If foil or compound on CALVERT holder, plot I2/I0 or DIODE/I0
  • When the sweep is complete, while still in the plotter window- click “Modify” and then “Derivative”
  • Copy the highlighted value for the energy of the first large peak in the derivative (autoselected by the plotter in the list of energies)
  • In the Mono controls:
    • Send the Mono to the copied value from the derivative
    • In the Calibrate tab: Set to the known/book value.
  • If CALVERT has been moved to its IN value, move it back to its OUT value of CALVERT = 4 !!

Now you are able to move on with loading and aligning samples, windowing the detector (if using the 7-element Vortex detector), and running measurements!
