RaDMaX (radiation damage in materials analysed with X-ray diffraction) is a user-friendly graphical program that allows the determination of strain and damage depth profiles in ion-irradiated crystals. This task is achieved by fitting experimental X-ray diffraction data, recorded in symmetrical theta-2 theta geometry, with a dynamical diffraction model parametrized with variable strain and damage profiles based on B-spline functions. The strain and damage profiles can be graphically manipulated so as to fit the calculated curve to the experimental data. Automatic fitting procedures (generalized simulated annealing and conventional least squares) are also implemented. RaDMaX is free and open source (CeCILL licence) and can be downloaded from http://aboulle.github.io/RaDMaX.
