The canSAS-2023 Workshop, canSAS-XIII, will be hosted by the Institut Laue Langevin (ILL) and the European Synchrotron Radiation Facility (ESRF) in Grenoble, France from 16-18 October 2023.


The acronym canSAS stands for collective action for nomadic Small Angle Scatterers. It is a bottom-up effort originally initiated in Grenoble by Ron Ghosh (ILL), Roland May (ILL), Claudio Ferrero (ESRF) and Wim Bras (DUBBLE CRG) in 1998. Ever since it has been an ongoing activity to provide the small-angle scattering user community with shared tools for data reduction and analysis, and disseminating other pertinent information ( Lately the focus has been on data analysis and modelling software, instrument resolution corrections and other issues related to data interpretation.

The last formal workshop was held in Freising, Germany in 2019 ( The following meeting planned in Delaware did not take place due to the Covid-19 pandemic. As 2023 represents the 25th Anniversary of canSAS it seemed only fitting that this Workshop should return to its birthplace!

CanSAS-XIII will be of particular interest to instrument scientists and users who are deeply involved in the development of new software tools or analysis methods.

The following topics are expected to be covered during the workshop:

 -AI-based methods for data collection and data mining
 -ML-based SAS data analysis
 -Needs and developments of analysis programs
 -Emerging sample environments and methods
 -SAS-based imaging (tensor tomography, USAS imaging, ptychography, CXDI, etc.)
 -Simultaneous SANS/SAXS fits
 -Background corrections
 -Refraction/Reflection effects
 -Anisotropic scattering & fiber diffraction
 -Open access, open data, FAIR principles
 -Enhancing collaboration between facilities worldwide

There will be a mixture of plenary sessions and breakout groups with extensive discussion and posters. And the canSAS working groups will report on their activities.
