Summary

This is a routine to load in the beam monitors from SNS preNeXus files into a workspace.

Alias

This algorithm is also known as: LoadPreNeXusMonitors

Properties

Name Direction Type Default Description
RunInfoFilename Input string Mandatory The filename of the runinfo file for a particular run. Allowed Values are: _runinfo.xml. Allowed extensions: [‘_runinfo.xml’]
OutputWorkspace Output MatrixWorkspace Mandatory The workspace to load the monitors into.

Description

This algorithm reads in the filenames of the monitors from the runinfo file. It will only work with histogram monitors and assumes that all monitors are on the same time axis. It also assumes that the beam monitor files are in the same directory as the runinfo file.

Usage

Example - Loading PreNexus Monitors

# CNCS_7860_runinfo.xml references 3 beam monitor files.
monitor_ws = LoadPreNexusMonitors("CNCS_7860_runinfo.xml")

print "The resulting workspace contains %i spectra -- one for each monitor." % monitor_ws.getNumberHistograms()

Output:

The resulting workspace contains 3 spectra -- one for each monitor.
