    • The following is the agenda of work posted under business. Please add comments here:
    • Purpose and goals: Intercomparison of data measured on the same sample with different instruments and different techniques (SAXS, SANS, light scattering etc.) can prove valuable in a number of ways. In particular it aids understanding of details of the experimental methods and it can help assess reliability. In a similar way, looking at results of data reduction or analysis generated with different software can provide valuable information about performance and verification of methodology. Specifically these activities should:
      • Provide Quality Assurance/Quality Control,
      • Improve (reduce) uncertainties of SAS measurements in general,
      • Help each facility continuously improve performance and quality of data.
    • We will discuss what types of tests are interesting/important:
      • Beam intensity standards - there are several different ways to quantify this
      • Standards to test resolution
      • Absolute intensity calibrations,
      • Materials for Q calibration,
      • etc. etc,
    • Some other related issues:
      • Inelastic,
      • Multiple scattering,
      • Wavelength contamination,
      • Detector efficiencies at different wavelengths
      • limits in signal to noise - how weak a signal can be reliable extracted;
      • etc.
    • Outcomes needed are:
      • A written plan to sustain long term effort in this area
      • This should describe how to seed, co-ordinate and publicise “ad-hoc” projects ,
      • Assess how frequently exercises can be undertakem
      • Define good ways to disseminate/share results. This will including “advertising” projects and using them as input for other activities.
    • We should aim to define a list of 2 or 3 projects for work in the near term. This should include a plan of action and participants for each.
    • We shoud have a plan for presentation at SAS 2012. (This might just be an announcement of the plan and see who wants to participate?.)
