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:

Pick the type of monochromator used:

Enter the monochromator angle in degrees:

Enter the FWHM for the first reflection in degrees:

Enter the FWHM for the second reflection in degrees:


Results:

Energy Spread (deltaE/E)= Or keV.

Divergence= radians.
