Preliminary Agenda

  1. updates of action items and items in progress
    • From canSAS VI
      • SAS Portal
      • 1D and 2D data formats
      • Standards - Extension of mailing list archives
      • IGOR develper's progress?
      • Is there a need for a GISAS working group?
    • From last meeting
      • World SANS directory (SAXS?)
      • Anybody besides Bruker come to canSAS session?
      • Long pulse spallation source project update if any?
    • Any other working group etc update?
  2. Discussion regarding next canSAS meeting in 18 months and in Sydney (see notes from canSAS-VI)
    • 18 months = when and where
    • Sydney meeting. what format?
  3. Discussion on including other facility representation
  4. Discussion of portal issues and possible repository of SAS information
    • e.g. data for windows and sample environments (see notes from canSAS-VI)
  5. Other issues and/or news from around the world

Minutes

  1. updates of action items and items in progress
    • From canSAS VI
      • SAS Portal
        • Paul has investigated finding a student and has identified funds.
      • 1D and 2D data formats
        • Pete - Nexus code camp has lead to a SAS format definition that he will post the URL to so we can review it and comment.
        • http://trac.nexusformat.org/definitions/browser/trunk/applications/NXsas.nxdl.xml defines minimum set of tags/info for small angle scattering. NB - this is for monochromatic scattering only : TOF and GI not considered.
        • Timeline for NXDL? (AJJ) - PRJ says approx. 6 months.
        • AJJ - Make sure we are really talking about reduced data. What is needed to allow the NXsas to be used for TOF data?
        • PRJ/SK - Have added namespaces to handle wavelength dependent transmissions etc.
        • RH/AR - Handling different q-space maps / detector geometries?
        • CF - noting meeting : http://www.esrf.eu/events/conferences/hdf5/hdf5/
        • PRJ - Action: Review of NXsas format?
        • Action: Get some North American people to CF's meeting.
        • AR to PRJ - any planned tools to read NXsas. Answer - Ideas: Translation app or browser/plotting app. Best answer would be strong bindings for various languages.
        • Watch and wait on nexus before leaping in to 2D.
        • PRJ - Licensing. Need debate within working group.
        • AR - Update on 1D usage? AR wrote to ILL (Andrew Harrison) regarding use of format and has had no response. AJJ - NCNR will support in next release. No other updates.
        • CF suggested that AR goes to visit new SAS beamline.
      • Standards - Extension of mailing list archives
      • IGOR develper's progress?
        • AJJ Talked with Jan Ilavsky.
        • AJJ asked KL for his current code to test compatibility.
      • Is there a need for a GISAS working group?
        • Continue to hold on this. AR - put high on agenda for next discussion. Should think about we should involve the reflectometry community.
    • From last meeting
    • Any other working group etc update?
  2. Discussion regarding next canSAS meeting in 18 months and in Sydney (see notes from canSAS-VI)
    • 18 months = when and where
      • Agreed. Probably focused on 1D/2D.
      • North Americans will formulate a plan for next meeting.
    • Sydney meeting. what format?
      • Daniel? Meeting should be before SAS so that the results of discussions can be presented in body of SAS meeting in session.
      • EG : Suggests a 2day, Thu/Fri before SAS. No objections raised.
      • Who convene? Facilities? Location? Should we include GI and Refl?
  3. Discussion on including other facility representation
    • SSRL / PSI / AU Synch.
  4. Discussion of portal issues and possible repository of SAS information
    • e.g. data for windows and sample environments (see notes from canSAS-VI)
  5. Other issues and/or news from around the world
    • Detectors
      • Koreans now have detector. Not tested with neutrons. ORNL have bioSANS detector working now. Local limit to 100 cps, global to 25000 cps.
      • RH has his detector working OK with new power supplies
      • SK - problems with discriminator cards. Gone through 5 total across two detectors.
      • KL - grounding and noise issues.
    • Long shutdowns
      • PDB - Repository of info about long shutdowns?
      • Could it go in SANS directory?
    • SANS/SAXS collaboration
      • ILL/ESRF can now do rolling proposals for time on neutrons and x-rays. Initiative based around EMBL/ESRF/ILL - structural biology.
