Summary ¶

Load a file or range of files created by the nGEM detector into a workspace.

Properties ¶

Name	Direction	Type	Default	Description
Filename	Input	list of str lists	Mandatory	The name of the nGEM file to load. Selecting multiple files will combine them into one workspace. Allowed extensions: [‘.edb’]
OutputWorkspace	Output	Workspace	Mandatory	The output workspace
BinWidth	Input	number	10	The width of the time bins in the output.
MinEventsPerFrame	Input	number	0	The minimum number of events required in a frame before a it is considered ‘good’.
MaxEventsPerFrame	Input	number	Optional	The maximum number of events allowed in a frame to be considered ‘good’.
GenerateEventsPerFrame	Input	boolean	False	Generate a workspace to show the number of events captured by each frame. (optional, default False).

Description ¶

The LoadNGEM algorithm will read .edb files generated by the nGEM detector.

The detector produces files that are up to 1GB in size, so if the collection produces more than 1GB of data, it will create a new file to write the rest of the data to. When all of the files are selected they are loaded into a single workspace containing all of the events.

The loading process allows the option to include a count of the number of events in each frame (begun by a T0 event), which is loaded as a plottable workspace. This can then be used to determine what is considered a “good frame” so that only good frames are included in the final data.
