Properties

Name	Direction	Type	Default	Description
Filename	Input	string	Mandatory	File path of the Data file to load. Allowed extensions: [‘.nxs’]
OutputWorkspace	Output	MatrixWorkspace	Mandatory	The name to use for the output workspace
LoadDetectors	Input	string	Spectrometer	Select the type of data to load from IN16B. Allowed values: [‘Spectrometer’, ‘Diffractometer’]

Description

This algorithm loads a .nxs file produced by IN16B back-scattering spectrometer at ILL. It supports both QENS and FWS types of data, both with or without mirror sense. The number of active single detectors, and their actual positions are read from the .nxs file overriding the ones in the instrument definition. The output workspace will be dimensionless containing the number of counts per energy channel for each detector pixel. It will have empty x-axis unit. The LoadDetectors allows to choose which data to load for IN16B: those acquired by the spectrometer, or those from the diffractometer. Usage —–

Example - Load ILL IN16B NeXus file:

# Load ILL IN16B data file into a workspace 2D.
ws = LoadILLIndirect('ILL/IN16B/136555.nxs')

print("ws has {0} spectra and {1} bins".format(ws.getNumberHistograms(),ws.blocksize()))

ws has 2051 spectra and 2048 bins
