QUAD - QUAntitative Diffraction
A software toolbox for x-ray dynamical diffraction for strained crystals
About
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
- Stable and fast algorithm for simulation of light-scattering within strained crystals.
- Full treatment of absorption, multiple scattering and multiple diffraction
- Script language interface (LUA) for maximum flexibility
