This is an online home for the open reflectivity standards organisation (ORSO), a collaborative network of scientists interested in neutron and X-ray reflectometry.

The inaugural meeting of what has now become ORSO (Open Reflectivity Standards Organisation) took place at the end of October 2019. The meeting had participants from a large number (though not all) of X-ray and neutron facilities from around the world. There was general agreement that there should be some collaboration within reflectivity, towards the standardisation of data formats, reduction, and analysis. A series of working groups were set up. This organisation and working groups are open to all, to join a working group please just sign up on the message board or contact the group chair. Additionally, there is a GitHub organisation that administers this webpage that you can become an owner of by contacting Andrew.

The next meeting of ORSO was planned to take place as a satellite to SXNS16 in Lund in June 2020, but was moved online

    Following a successful first meeting in Abingdon, UK in October 2019, the second reflectivity data, reduction, and analysis standardisation workshop will be held as a satellite meeting of SXNS16 at the European Spallation Source ERIC in Lund, Sweden in June 2020.
