X-ray Calculations: Energy Analyzer

What type of crystals make up the monochromator? Enter Theta 1 of the analyzer crystal in degrees: Enter Theta 2 of the analyzer crystal in degrees: Pick the Miller indicies for the first reflection: Pick the Miller indicies for the second reflection:

Results

Energy: keV Wavelength: Å Actual 1st Theta: ° Actual 2nd Theta: ° Offset: °

Note: The following are calculated with series solutions and are therefore approximate.

Structure factors:

1st: 2nd:

Theoretical Darwin widths:

1st: arc sec. 2nd: arc sec.

Check to calculate energy resolution and fill in the following:
