Indirect Tools

Overview

../_images/Tools_interface.png

The Indirect Tools interface contains useful tools that do not fit into the other interfaces.

Transmission

../_images/Tools_tabTransmissionCalc_widget.png

The Transmission tab is used to calculate the sample transmission for a given sample on a given instrument configuration, this can then be used to determine the sample shape and dimensions prior to an experiment.

Currently this is interface supports ISIS and SNS spectrometers.

Options

Instrument
Instrument intending to be used.
Analyser
Analyser bank intending to be used.
Reflection
Reflection number of the planned instrument configuration.
Chemical Formula
The chemical formula of the sample material, in the format used by the SetSampleMaterial algorithm.
Number Density
The density of the sample in atoms/\mathrm{\AA{}}^3.
Thickness
The thickness of the sample in cm.

LoadILL

../_images/Tools_tabLoadILL_widget.png

The Load ILL tab is used to read data files generated by other facilities (i.e. not ISIS or SNS). At present the only supported instruments are the ILL Indirect Geometry spectrometers IN10, IN16 and IN13 (the latter is still a work in progress).

The LoadILL tab operates on either .asc (raw data) or .inx (S(Q, \omega) reductions) files. To begin, start by selecting a relevant file using the file browser. The interface will attempt to choose the relevant instrument for you based on the file name. If the selected instrument currently being displayed is not the one you desire it can be changed from selecting it in the selection box. You may also select the relevant analyser and reflection to use.

Options

Run
Run/reduction files to load.
Instrument
Instrument used for experiment (set automatically based on filename if possible).
Analyser
Analyser bank used for experiment.
Reflection
Reflection number used for experiment.
Use Map & Map File
Allows filtering the spectra using a map file.
Reject Zero
If selected will remove any spectra that have no counts.
Verbose
Enables outputting additional information to the Results Log.
Plot Result
Allows each result to be plotted as either a spectrum plot or contour plot.
Save Result
If enabled the loaded reductions will be saved as NeXus files in the default save directory.
