Indirect Tools

Overview

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

Action Buttons

Settings
Opens the Settings GUI which allows you to customize the settings for the Indirect interfaces.
?
Opens this help page.
Manage Directories
Opens the Manage Directories dialog allowing you to change your search directories and default save directory and enable/disable data archive search.

Transmission

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 interface supports ISIS and SNS spectrometers.

Options

Instrument
Instrument intending to be used.
Analyser
The analyser bank used for the experiment.
Reflection
The reflection number of the planned instrument configuration.
Chemical Formula
The chemical formula of the sample material, in the format used by the SetSampleMaterial algorithm.
Mass/Number Density
The density of the sample in :math: g/cm^3 or atoms/\mathrm{\AA{}}^3.
Thickness
The thickness of the sample in cm.
Run
Runs the processing configured on the current tab.

LoadILL

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
The instrument used for the experiment (set automatically based on filename if possible).
Analyser
The analyser bank used for the experiment.
Reflection
The reflection number used for the experiment.
Use Map & Map File
Allows the filtering of spectra using a map file.
Reject Zero
If selected, it will remove any spectra that have no counts.
Run
Runs the processing configured on the current tab.
Plot Result
Plotted the parameter as either a spectrum plot or contour plot upon the completion of processing.
Save Result
Saves the result in the default save directory upon the completion of processing.
