canSAS-X Workshop

  • date: Sunday, October 7, 2018
  • place: Peninsula Room C, Grand Traverse Resort & Spa, Traverse City, Michigan, USA
  • (just before SAS2018)



canSAS (Collective Action for Nomadic Small Angle Scatters) workshops and activities are self assembled/bootstrap efforts to provide a forum for SAS users and providers to come together to discuss common needs and issues, to learn from each others experiences, discuss current best practices, hear about emerging techniques, and importantly to identify areas where the field/state of the art could be improved by bringing together the people that are interested and able to work cooperatively to solve the problem (see canSAS-IX#Goals).

As of canSAS VIII in Tokai, Japan, the goal is to have a full independent workshop every three years, half way between the triennial SAS meetings, followed by some kind of forum at the SAS meetings themselves. These last have ranged in form from a half day session to just a lunch session to disseminate the status of activities. The intention is that the work agreed upon to solve current common problems will take place in the intervals between meetings, either at focused targeted workshops (see canSAS-2012), at ad-hoc gatherings of self-assembled working groups in person, or remotely.

At SAS2018 the organizers have arranged for space for sattelites the days prior and subsequent to the meeting proper and provided canSAS a day long block prior to the meeting itself.


The goals for this one-day workshop are to get a status report on activities kicked off at canSAS IX and since, prepare for the next full, free standing canSAS workshop to be held in Freising, Germany from 8 to 10 July 2019, and provide a discussion forum for current active topics.

Venue and Registration

  • date: Sunday, October 7, 2018
  • place: Peninsula Room C, Grand Traverse Resort & Spa, Traverse City, Michigan, USA
  • (just before SAS2018)

Note that as a "grass roots" community effort there are generally no specific funds to support the local organizing expenses of such meetings. Instead these expenses will be covered through mostly small registration fees asked of each participant. (Expect $30 to cover the two coffee breaks). Lunch is not included.

Meeting Topics

The topics being addressed at the canSAS X workshop are:

  • Status of ongoing activities
  • canSAS XI planning. Practical information at
  • NXcanSAS data formats and proposed improvements.
    • improve the description of how Q should be provided in the HDF5 file
    • Other needs?
  • Planning new round-robin samples/measurements/data treatment
    • Geosciences USAS: rocks/shales
    • particle sizing standards?
    • Other candidates?
  • Collaborative opportunities for advancing data analysis tools
    • COST action
    • International "networking" or "collaboration grants
    • Other
  • disseminate information about canSAS and to recruit active participants to canSAS activities
  • Other topics as might be of interest to those present - everyone is welcome to raise ideas as to what needs to be done and how to progress. There is a specific 'Open Mic' period in the timetable.

Report on the Meeting

Everyone is encouraged to contribute to the meeting report and to post slides and other relevant material.

  • The introduction to canSAS (P. Butler, A. Rennie) described briefly the activities and the success over the past 20 years since the first meeting in Grenoble, France. Particular aims for the day were reiterated with an emphasis that there are many on-going and new activities. Today there should be reports on status and plans for actions. A significant aim should be to prepare for the workshop next year in Freising, Germany (8-10 July 2019):

Introductory Slides. Presentation
