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¶

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.

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.
