Direct Inelastic Changes

Interfaces

New

  • Added the ability to manually specify a temperature for a set of runs in the TOFTOF reduction dialog.

Improvements

  • PyChop has been updated to calculate rep-rate multiplication for MAPS and MARI. In addition, it now supports loading instrument parameters from a YAML file, and also plots the Q-E coverage.
  • Workspaces used in MSlice are no longer added to the MantidPlot window automatically, and can be added using the Save To MantidPlot button.
  • Improved default limits for 2D plots of large datasets in MSlice.

Algorithms

New

Improvements

  • DirectILLDiagnostics:
    • it is now possible to set the thresholds for elastic peak and noisy background diagnostics in the IPFs
      • ILL’s IN6 now sets its own default PeakDiagnosticsLowThreshold
    • a hard mask is applied over the beamstop region of IN5
    • user masked detectors are not included in the report anymore
  • DirectILLReduction:
    • all output workspaces are now converted to distributions, i.e. the histograms are divided by the bin width.
    • The default \(Q\) binning has been revised.

Bugfixes

Deprecated

Instrument Definitions

  • The source component of ILL’s IN5 has been moved from \(z = -2\) to \(z = -2.10945\) meters and renamed to frame-overlap_chopper.
  • The source component of ILL’s IN6 has been moved from \(z = -0.395\) to \(z = -0.595\) meters and renamed to suppressor_chopper.
  • ILL’s IN4 and IN6 now validate the wavelengths and chopper speeds in MergeRuns.
  • New CNCS geometry and parameters for 2018B cycle
  • ARCS and CNCS are configured for live data

Python

Improvements

  • The plotting methods in the directtools python module now support logarithmic scales.
