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), Peter Timmins (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!
