Geometric efficiency calculation

The geometric efficiency calculation window allows for calculating the geometric detection efficiency for a certain measurement setup. Like the simulation, the geometric efficiency calculation can be started in variety of ways:

Using the geometric efficiency calculation window
Calculating geometric efficiency using the run menu
Calculating geometric efficiency using a keyboard shortcut

Using the geometric efficiency calculation window

In the geometric efficiency calculation window the measurement setup can be specified using the following controls:

'The source detector distance' field

The distance of the source from the detector. Note that the source and the detector geometries are coplanar and this is the distance between the planes that contain them.
The 'detector diameter' field

The diameter of the detector window for geometric efficiency calculation. The detector window geometry is a disc with this diameter, coplanar with the xy-plane.
The 'desired standard deviation' field

The desired standard deviation to achieve by the calculation. Smaller values will yield more accurate results at the cost of longer running time.
The 'source diameter' button

Select to specify the diameter of the source. With this option the source geometry is a disc with the specified diameter in the xy-plane
The 'point source' button

Select to specify a point source. With this option the source is a point in the xy plane. Note that the source-detector distance is the distance between the planes that contain the source and the detector.

Depending on the source geometry type selected you may use further controls to specify the properties of the source. For disc source:

The 'source diameter' field

Use this field to specify the radius of the disc shaped source.

For a point source:

The 'x' field

Use this field to specify the x-coordinate of the point source.
The 'y' field

Use this field to specify the y-coordinate of the point source.

Calculating geometric efficiency using the run menu

Using the run menu is a quick way to run the geometric efficiency calculation without turning to the calculation page. Selecting the run geometric efficiency calculation item in the run menu will cause a geometric efficiency calculation window to pop up. This can then be used exactly like the one in the calculation page. See Using the geometric efficiency calculation window

Calculating geometric efficiency using a keyboard shortcut

Using the keyboard shortcut is the fastest way to get to the geometric efficiency calculation. It behaves exactly like the run geometric efficiency calculation item in the run menu. See Calculating geometric efficiency using the run menu and Using the geometric efficiency calculation window
