Minutes
- 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.
- SAS Portal
- From last meeting
- World SANS directory (SAXS?)
- AR prodded Ralf and it was updated. AR - people need to send Ralf info. ACTION: NIST and ISIS will update.
- http://www.ill.eu/instruments-support/instruments-groups/groups/lss/more/world-directory-of-sans-instruments/
- AR - PRJ was going to look at directory of SAXS. PRJ is going to build a web page with form for people to fill out. Essential PRJ is on it.
- Anybody besides Bruker come to canSAS session?
- Long pulse spallation source project update if any?
- KL will let people know about report from Rome meeting.
- World SANS directory (SAXS?)
- Any other working group etc update?
- From canSAS VI
- 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?
- 18 months = when and where
- Discussion on including other facility representation
- SSRL / PSI / AU Synch.
- Discussion of portal issues and possible repository of SAS information
- e.g. data for windows and sample environments (see notes from canSAS-VI)
- 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.
- Detectors
