New beta version: 2.43 (18 March 2014) download it here

Stable version: 2.33 (18 August 2011)  

Maud 2.33

by Luca Lutterotti, 1997-2013


MAUD stands for Material Analysis Using Diffraction. It is a general diffraction/reflectivity analysis program mainly based on the Rietveld method, but not limited to.

The main features are:

  • Written in Java can run on Windows, MacOSX, Linux, Unix (need Java VM 1.6 or later)
  • Easy to use, every action is controlled by a GUI
  • Works with X-ray, synchrotron, Neutron, TOF
  • Developed for Rietveld analysis, simultaneous multi spectra and different instruments/techniques supported
  • Ab-initio structure solution integration, from peak finding, indexing to solving
  • Different optimization algorithms available (LS, Evolutionary, Simulated Annealing, Metadynamics)
  • Le Bail fitting
  • Quantitative phase analysis
  • Microstructure analysis (size-strain, anisotropy and distributions included)
  • Texture and residual stress analysis using part or full spectra
  • MEEM and superflip algorithm for Electron Density Maps and fitting
  • Thin film and multilayer aware; film thickness and absorption models
  • Reflectivity fitting by different models, from Parratt (Matrix) to Discrete Born Approximation
  • Works with TEM diffraction images and electron scattering
  • Several data files input formats
  • Works and input images from 2D detectors (image plates, CCD)
  • CIF compliance for input/output; import structures from databases
  • Many other features......look at the Maud in action page.

For the texture/stress part it is based on the RITA/RISTA method by H.-R. Wenk, S. Matthies and L. Lutterotti (see references and picture). Other researchers contributing to the development of the methodology include M. Ferrari (micromechanic), N. C. Popa (for the Line Broadening), R. W. Grosse-Kunstleve with SgInfo, L. Cont and M. Bortolotti (Java development). Special thanks go also to S. Gialanella and the Center for Materials Science of the Los Alamos National Laboratory for supporting the work.

Sorry the manual is still in progress, there are some tutorials at the present. Now that version 2.0 is out the manual will have the priority

To download the program go here or choose Download from the menu on top or on the left panel

The old Maud 1.99x is still available, follow the link on the left panel. It is recommended to use the new version, but the input/output analysis files are incompatible (Maud version 2.x can read the old format but the old program cannot read the new one completely). So because the GUI and some models (absorption) has changed, some peoples may prefer to stick with the old one (not advisable). The old program will remain also for the museum.
