canSAS-2012

Meeting of canSAS working groups

Purpose

Work on specific matters important to the canSAS community as decided in previous conference calls. It is expected that those attending this working session will already have strong foundation and understanding and will come ready with knowledge, tools, and ideas to make significant progress during the event. The specific projects and tasks, as well as the list of participants, are described on this wiki and will be revised as the event draws near.

Outcomes

• 2-d data format
• A plan for standards
• Global SAS Web Portal
• presentation at SAS2012

Planning

Business Matters

• Re-enunciate purpose and benefits of a standard reduced data format
  • 1D Format
  • agree a proposed foreign namespace extension of the current 1D standard (required to enable, for example, t-o-f instruments to store auxillary wavelength-dependent non-I(Q) data in the same output files)
    • see Section 1.6.5 in here
    • and look at this example
    • but this is not what should be done!
  • agree resultant changes to the schema/stylesheet

   ARJN - I would recommend that during this meeting that the current format then be 'parked', the new 2D format
          should be flexible enough to handle 1D and 2D data

• • 2D Format
  • define minimum necessary for reduced data
    • review previous discussions on 2D
    • considerations specific to 2D reduced data
    • consider forward looking issues such as
      • grazing incidence
      • event mode analysis
  • suggest format framework (NeXus extension, canSAS 1D extension, other) with brief discussion of the reason for the choice (including options considered, pros and cons of each, and final weighing)
    • compare with NeXus definitions for:
      • NXsas
      • NXiqproc
  • Guide to how to make implementation easy.
  • Create straw format suitable for test/demonstration use and convert some test data for such a demonstration.
  • Provide a plan for presentation at SAS 2012
• Standards
  • Define purpose/goals
    • (e.g. QA/QC,
    • improvement in uncertainties of measurements in general,
    • helping each facility continuously improve
    • etc.)
  • what types of tests are interesting/important
    • (e.g. beam intensity standards - there are several different ways to quantify-
    • ? resolution?
    • abs intensity calibration,
    • Q calibration,
    • etc. etc,
  • other contribution issues -
    • inelastic,
    • multiple scattering,
    • wavelength contamination,
    • detector efficiencies at diff wavelengths etc..;
    • limits in signal to noise - how weak a signal can be reliable extracted;
    • etc etc etc)
  • written plan for long term sustaining of effort
    • (assuming “ad-hoc” projects how to seed them,
    • how frequently, and
    • how to disseminate/share results including “advertizing:” project
  • Define list of 2 or 3 projects to work on in the near term including plan of action and participants for each.
  • plan for presentation at SAS 2012 (could be just to announce plan and see who wants to participate?)
• Global SAS Web Portal
  • define scope, purpose, and goal of portal
  • list content type to which such a portal should give access.
  • Suggest method for hosting
    • ?more distributed or more centralized,
    • ?under auspices of a particular facility or SAS commission
    • ? .. or both etc)
  • Build a working straw landing page prototype
  • Build at least 2 or 3 subpages and/or designs on paper
  • plan for presentations
    • SAS 2012
    • SAS commision
