canSAS-2012

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.

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
  • Report Page : 2012 Data Working Group Report
• Standardisation - intercomparison of measurements and software for data reduction and analysis so as to assess experimental and intstrumental reliability
  • Discussion Page : 2012 Standards Discussion
  • Report Page: StandardsGroupReport
• 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
  • Report Page : 2012 Web Working Group Report

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

Standard Reduced Data Format

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

• Re-enunciate purpose and benefits of a standard reduced data format
• 1D Format
  • agree a proposed extension of the current 1D standard
• 2D Format
  • define minimum information 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

Standards and Calibrations

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

Global SAS Web Portal

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

• 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

Projects and Tasks

These items are sorted in order of priority that they be finished.

1. 2-D format
2. Standardization
3. SAS web portal

Presentations

These presentation were given on the first day:

• Pete Jemian (APS): Status and challenges at the APS
• Andrew Jackson (ESS): Thoughts on Data Formats and Web Portals
• Adrian Rennie (Uppsala University): Introduction to Standardisation (from the first webinar)

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, ...)

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.

You can also take the bus 801 from Arlanda Airport to Uppsala which departs every 30 minutes and takes about 40 minutes. The buses leave from stop number 13 (there is a stop with this number outside each terminal). Tickets can be bought at the airport or with a Swedish mobile phone or a Visa/Master Card on the bus. Cash is not accepted on the bus.

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.

Final Report

Draft versions of the reports of work of groups at the meeting can be found at:

Group Reports

Data Format Group http://www.smallangles.net/wgwiki/index.php/2012_Data_Working_Group_Report

Standards Group http://www.smallangles.net/wgwiki/index.php/StandardsGroupReport

Web Portal Group http://www.smallangles.net/wgwiki/index.php/2012_Web_Working_Group_Report

The new web portal for the small angle scattering community is http://www.smallangle.org/

General Remarks

The work in these areas is ongoing. Specific actions have been identified by the work groups. Some general activities that encompass several themes will be:

• A presentation and discussion session will be held at the SAS2012 Conference in Sydney in November 2012. This will describe current and future activities and ask for broader participation.
• Updates to the work group mail lists will be required for technical reasons and the opportunity will be taken to review the membersip of the lists so that e-mail addresses of people that have not been active and not requested continued participation will be removed.

Acknowledgements

The results described arise from four full days of intensive work in small groups during the meeting in Uppsala and from preparatory work. We acknowledge the generous support of the agencies employing the particpants that have made available time and travel resources to permit the co-operative work. We are also grateful to people who have given freely of their own time to support the SAS community. Just the direct participation amounts to about two-person months of effort. These 'sponsors' are APS (Argonne National Laboratory), NCNR (National Institute of Standards and Technology), ISIS (STFC), the Diamond Light Source, the European Spallation Source, Institut Laue Langevin, University of Auckland, Kyoto University, University of Tokyo and Uppsala University. We are also grateful for further participation from ANSTO, APS and ESRF in webinars and by making contributions to discussion on the wiki.
