SANS Changes

Algorithms and instruments

New

  • New EQ-SANS instrument definition file to adjust the position of the detector array accoring to log entry “detectorZ”.
  • New D16 instrument definition file and loader to manage SANS data.

Improved

  • Detector numbering is fixed for the SANS instruments D22 and D33 at the ILL.
  • MaskBTP now handles both old and new instrument definitions for BIOSANS and GPSANS
  • SANSILLReduction and SANSILLAutoProcess are improved to better handle the absolute scale normalisation.
  • SANSILLIntegration will now offer to produce I(Q) for separate detector components separately, which is useful for D33.
  • SANSILLReduction will now allow for correct absolute scale normalisation even in circumstances when, for example, there is no flux measurement for the water run configuration.
  • SANSILLAutoProcess now supports gamma scans for D16 at the ILL.
  • Data with invalid proton charge logs will now be fixed before performing slicing. A warning is emitted when this happens.
  • ISIS history for top level algorithms now works correctly. A user can copy the history of a workspace to their clipboard or a file and the data will be reproduced on that machine without requiring editing of the script.

ISIS SANS Interface

Improved

  • The Beam Centre Finder will now print the average error in X, Y and the number of points considered. This allows for direct comparisons of different radius limits, which previously summed the difference across different numbers of points.
  • The beam centre finder correctly centres HAB and LAB banks; previously it only worked for LAB.
  • Batch CSV files can have their columns in any order and will load into the SANS GUI correctly.
  • Tabbing between columns has been improved in the data GUI table. Users can now single tab between unmodified columns, or double tab for modified.
  • Sample periods and geometry inputs have been move to the right of the table, as part of the tabbing improvements.

Fixed

  • A zero monitor shift did not previously account for the position of the rear detector for Zoom. A 0.0mm offset now works correctly when processing data from the SANS GUI or command interface.
  • The help documentation now loads correctly
  • Saving a CSV with sample geometry enabled, then reloading works correctly.
  • Hitting Shift+Enter on the top row no longer causes an error.

ORNL SANS Interface

  • A bug has been fixed where only facilities with applicable instruments can now be selected.
  • A bug has been fixed which was causing the interface to crash when selecting HFIR instruments.
