This is an online home for the Open Reflectivity Standards Organisation (ORSO), a collaborative network of scientists interested in neutron and X-ray reflectometry.

It is intended that this website contains information relevant to all levels of interst in reflectometry.

We have a number of educational resources for reflectometry and directories of reflectometry instrumentation.

ORSO is divided into four working groups which cover different aspects of this collaboration.
  • Education and outreach: The education and outreach working group aims to develop understanding of reflectivity techniques and disseminate information about reflectivity analysis.
  • File formats: This working group aims to draft a spec for a standard file format to be used across X-ray and neutron reflectivity. This is an important goal to move towards interoperability across facilities.
  • Data Analysis: The working group focused on data analysis is targetting a universal descriptive model language for reflectometry analysis. Additionally, they hope to develop test cases for reflectometry calculations to ensure robustivity across analysis software.
  • Reproducibility: The reproducibility working group is focused on creating guidelines to ensure reproducibility of data reduction and analysis of neutron and X-ray reflectivity measurements.
The organisation has had two workshops to date and more are planned. Details can be found here.

This organisation and working groups are open to all, to join a working group please just sign up on the message board, contact the group chair, or sign up to the mailing list below.
Additionally, there is a GitHub organisation that administers this webpage that you can become an member of by contacting Andrew.
