About the ADvanced DIffraction Environment

This is a cloud-based comprehensive platform for hosting tools for neutron powder diffraction experimental planning, quick Bragg and pair distribution function refinement, etc. Also, various Spallation Neutron Source (SNS) and High Flux Isotope Reactor (HFIR) instrument relevant tools are available.

The platform is hosted at the research cloud at ORNL and should be used for academic research ONLY. If the tool is involved in your research, please put the following in your ackownledgement,

This research used resources of the Compute and Data Environment for Science (CADES) at the Oak Ridge National Laboratory, which is supported by the Office of Science of the U.S. Department of Energy under Contract No. DE-AC05-00OR22725.

Additionally, if you are refining the total scattering data in Q-space with Rietveld-like approach, we STRONGLY recommend reading and citing the following work:
