If you are simulating a constant-wavelength experiment (e.g., a traditional laboratory x-ray source), you can adjust the wavelength(s) of your simulated radiation using the Wavelength window:

Hide To change the wavelength
  1. Choose the Diffraction > Wavelength command.

    The Wavelength window appears (either a sheet, for Mac, or a dialog, for Windows).

  2. Enter a wavelength (in Å units) for the radiation.

    • For X-ray diffraction you can choose between monochromatic (single-wavelength) or dual-wavelength radiation.

    • For electron diffraction you can enter the electron beam voltage, whereupon the wavelength will be calculated for you.

  3. Click the OK button to continue.

Hide To change the wavelength interactively
  1. Locate the Instrument group in the Parameters Inspector.

  2. Use the Wavelength slider to continuously vary the wavelength.
