- 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!
