====== QUAD - QUAntitative Diffraction ======

** A software toolbox for x-ray dynamical diffraction for strained crystals **

{{:remagx_icon_quad_transparent.png?nolink&200 |}}
QUAD is a scientific software to calculate the x-ray scattering of light of strained crystals by solving the Maxwell-equations exactly. Because of it's general approach it is capable to simulate a lot of x-ray techniques including powder diffraction, Laue scattering, x-ray absorption XAS, x-ray reflectivity, x-ray diffraction, multiple diffraction. Its strength is especially in the soft x-ray regime where dynamical effects can be very important.
====Features====
