canSAS-2012

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.

The three main themes are:

• Treated data format - developing a standard for multidimensional treated data and resolving issues that arise with the 1-d standard and its implementaion.
  • Discussion Page : 2012 Data Discussion
• Standardisation - intercomparison of measurements and software for data reduction and analysis so as to assess experimental and intstrumental reliability
  • Discussion Page : 2012 Standards Discussion
• Development of a Global SAS web portal. This should be a general point of entry for the community to find information about small-angle scattering.
  • Discussion Page : 2012 Web Discussion

This page provides discussion of the themes, preliminary work and ideas : 2012 Discussion

Outcomes

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

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 auxiliary wavelength-dependent non-I(Q) data in the same output files)
  • 2D Format
    • define minimum necessary for reduced data
    • 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)
    • 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

More details and suggestions are on the Discussion Page: 2012 Data Discussion .

• Standards
  • 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:
    • Discuss what types of tests are interesting/important, intensity, resolution etc.
    • Consider related issues: Inelastic, Multiple scattering, Wavelength contamination, Detector efficiencies at different wavelengths
  • 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 undertaken
    • 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 should have a plan for presentation at SAS 2012. (This might just be an announcement of the plan and see who wants to participate?.)

More details and suggestions are on the Discussion Page: 2012 Standards Discussion

• 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
  • 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 commission

Practical Matters

Registration

Please inform Adrian Rennie of your intention to particpate and send details of your arrival and departure dates. You should book the accommodation directly with the hotel - see below.

Hotel

Clarion Hotel Gillet, Uppsala
Dragarbrunnsgatan 23,
753 20 Uppsala, Sweden

• Expect hotel rate to be 570 SEK for 1 Single Bed (approximate, subject to change)
• Please reserve your own rooms directly with the hotel (website, phone, ...)

Please reserve your own rooms directly with the hotel. The quoted rate at the hotel should include breakfast. This hotel is in the centre of Uppsala (see map) and is a few minutes walk from the railway station.

Directions and Maps

• map to hotel: google directions from airport
• airport: Stockholm Arlanda (ARN): international
• taxi: Uppsala Taxi +4618 100000
• train: Trains from airport to Uppsala take about 20 minutes. Frequency every 30 minutes. map reference

The most convenient and fastest means to reach the hotel from the airport is usually to take the trains from Arlanda Central station (under SkyCity) to Uppsala. Upptåget trains leave the airport at xx:27 and xx:57 thoughout the day and take 20 minutes. The fare is 140 SEK (one way) and this can be paid with cash or by credit card at the ticket desk or using machines (red ticket machines - credit card only). If you plan to take a long distance train operated by Swedish Railways (SJ) you should buy different tickets. The hotel is a few minutes walk from the station in Uppsala.

If you plan to take a taxi you can prebook a taxi and there is a fixed rate from the airport to Uppsala. You should make certain that you use one of the Uppsala taxi companies if you simply go to the rank at the airport.
