PelicanCrystalProcessing v1

Summary

Performs crystal processing for ANSTO Pelican data.

Properties

Name	Direction	Type	Default	Description
SampleRuns	Input	str list	Mandatory	Comma separated range of sample runs, eg [cycle::] 7333-7341,7345
EmptyRuns	Input	string		Optional path followed by comma separated range of runs, looking for runs in the sample folder if path not included, eg [cycle::] 6300-6308
ScaleEmptyRuns	Input	number	1	Scale the empty runs prior to subtraction
CalibrationRuns	Input	string		Optional path followed by comma separated range of runs, looking for runs in the sample folder if path not included, eg [cycle::] 6350-6365
EmptyCalibrationRuns	Input	string		Optional path followed by comma separated range of runs, looking for runs in the sample folder if path not included, eg [cycle::] 6370-6375
EnergyTransfer	Input	string	0.0, 0.02, 3.0	Energy transfer range in meV expressed as min, step, max
MomentumTransfer	Input	string		Momentum transfer range in inverse Angstroms, expressed as min, step, max. Default estimates the max range based on energy transfer.
LambdaOnTwoMode	Input	boolean	False	Set if instrument running in lambda on two mode.
FrameOverlap	Input	boolean	False	Set if the energy transfer extends over a frame.
CalibrateTOF	Input	boolean	False	Determine the TOF correction from the elastic peak in the data.
TOFCorrection	Input	string		The TOF correction in usec that aligns the elastic peak.
AnalyseTubes	Input	string		Detector tubes to be used in the data analysis.
MaxEnergyGain	Input	string		Energy gain in meV used to adjust the min TOF with frame overlap.
FixedDetector	Input	boolean	True	Fix detector positions to the first run
OutputFolder	Input	string	Mandatory	Path to save the output nxspe files.
ScratchFolder	Input	string		Path to save and restore merged workspaces.
ConfigurationFile	Input	string		Optional: INI file to override default processing values. Allowed values: [‘ini’]
KeepReducedWorkspace	Input	boolean	False	Keep the last reduced workspace.

Description

Performs the reduction of pelican data from event data (two theta, time) to S(Q,w) for single crystal data. The algorithm will sequentially perform the PelicanReduction processing for all run numbers provided. The data is output in nxspe format and can be used by programs such as Horace to process single crystal inelastic neutron scattering data.
