Summary

Loads a SANS data file produce by the HFIR instruments at ORNL. The instrument geometry is also loaded. The center of the detector is placed at (0,0,D), where D is the sample-to-detector distance.

Properties

Name	Direction	Type	Default	Description
Filename	Input	string	Mandatory	The name of the input xml file to load. Allowed extensions: [‘.xml’]
OutputWorkspace	Output	Workspace	Mandatory	The name of the Output workspace
Wavelength	Input	number	Optional	Optional wavelength value to use when loading the data file (Angstrom). This value will be used instead of the value found in the data file.
WavelengthSpread	Input	number	Optional	Optional wavelength spread value to use when loading the data file (Angstrom). This value will be used instead of the value found in the data file.

Description

This Loader reads XML data files from HFIR SANS Instruments (BioSANS and GPSANS) created by the SPICE data acquisition. It places the detector(s) at the right position and sets some properties necessary for posterior data reduction.

For both BioSANS and GPSANS places the main detector at the right distance. In the case of the BioSANS rotates the wing detector to the right angle.

Finds and sets the logs:

• beam-trap-diameter

• wavelength

• wavelength-spread

• wavelength-spread-ratio

• monitor

• timer

• sample-thicknes

• source-aperture-diameter and source_aperture_diameter

• sample-aperture-diameter and sample-aperture-diameter

• number-of-guides

• sample-detector-distance, sample_detector_distance, and sdd

• source-sample-distance and source-sample-distance

• beam-diameter
