IndirectDiffScan dialog.

Summary

Runs an energy transfer reduction for an inelastic indirect geometry instrument.

Properties

Name Direction Type Default Description
InputFiles Input str list   Comma separated list of input files
LoadLogFiles Input boolean True Load log files when loading runs
Instrument Input string Mandatory Instrument used during run. Allowed values: [‘IRIS’, ‘OSIRIS’]
SpectraRange Input int list 0,1 Comma separated range of spectra number to use.
SampleEnvironmentLogName Input string sample Name of the sample environment log entry
SampleEnvironmentLogValue Input string last_value Value selection of the sample environment log entry. Allowed values: [‘last_value’, ‘average’]
OutputWorkspace Input string Output Workspace group for the resulting workspaces.

Description

This algortithm is to speed up the workflow for Indirect Inelastic diffraction reduction. Uses ISISIndirectDiffractionReduction in diffspec mode with several parameters at fixed values. Also extracts the temperature from each run and creates a workspace of all runs with respect to temperature.

Usage

Example - Running IndirectDiffScan.

ISISIndirectDiffractionReduction(InputFiles='IRS21360.raw',
                                 OutputWorkspace='DiffractionReductions',
                                 Instrument='IRIS',
                                 SpectraRange=[105,112])

ws = mtd['DiffractionReductions'].getItem(0)

print('Workspace name: %s' % ws.name())
print('Number of spectra: %d' % ws.getNumberHistograms())
print('Number of bins: %s' % ws.blocksize())

Output:

Workspace name: iris21360_diffspec_red
Number of spectra: 1
Number of bins: 1934
