Mark your calendars! The next canSAS workshop will be held just prior to SAS2024 in Taipei Taiwan Nov 16-18, 2023.

About canSAS

The collective action for nomadic small angle scatterers (canSAS) is an ongoing activity to provide the small-angle scattering user community with shared tools and information.

This work involves both users and facilities and currently includes:

The use of both neutrons and X-rays is widespread and co-operation between these facilities and the user community has been fostered by working groups that address specific fields.

Meetings and Working Groups

Meetings are held every couple of years or as a need arises. The style varies between working meetings and more traditional conferences.
More information about the meetings and working groups can be found on our wiki
Reproducibility & Reliability
The reproducibility and reliability working group has arranged round-robin measurements of samples as calibrants and to compare results. There is also ongoing discussion about handling different sources of error in SAS data (e.g. systematic vs statistical).
Data Formats
For easy exchange of data from multiple facilities, and to meet possible data deposition requirements, the data formats working group has developed formats for 1-dimensional reduced data and multi-dimensional reduced data
As of early 2017, for new work, it is recommended to use the NXcanSAS (multi-dimensional) standard for both 1-D and n-D data to maximize the chance that other software will be able to read your data files.
SAS Information
The group on SAS information and education has been working with the IUCR SAS Commission to develop a web portal for small angle scattering. This is found at
Grazing Incidence
The Grazing Incidence Working group discusses issues related to developing standards and methods for the use of grazing incidence small angle scattering
