The name canSAS stands for Collective Action for Nomadic Small-Angle Scatterers. canSAS provides a forum for users, software developers and facility staff to meet and exchange ideas on all aspects of programming for X-ray and neutron small-angle scattering experiments. This includes experiment preparation and simulation through control to data-storage, reduction and analysis. The aim of the forum is to provide the best resources to the many nomadic experimenters who combine results measured at different facilities.

The aims of the canSAS meetings are to promote and simplify sharing SAS data analysis methods. Non-specialists will benefit from easily applicable methods for exchanging and merging of data from different synchrotron, laboratory and neutron facilities.

The canonical name for this format is cansas1d:1.1.

This work is the initiative of the canSAS 1D Data Formats Working Group, established at the canSAS-V workshop, NIST, Gaithersburg, Maryland, USA from October 29th to 31st 2007, which produced revision 1.0. A further workshop was held July 28th to 31st, 2012 at Uppsala University, Uppsala, Sweden which produced revision 1.1. The format derives many of its foundations from previous works such as the SASXML format, a joint collaboration between ISIS and ILL.

The home page of the canSAS 1D Data Formats Working Group describes the members, timelines, and current status. There is a discussion page for some matters that preceded this revision.
