Description

Sets up a sample shape and optionally a container shape, along with the required material properties, and runs the DiscusMultipleScatteringCorrection algorithm. This algorithm merely serves as a simpler interface to define the shape & material of the sample\container without having to resort to the more complex SetSample algorithm. The computational part is all taken care of by DiscusMultipleScatteringCorrection. Please see that documentation for more details. Currently the shape geometries supported are:

• Flat Plate

• Cylinder

• Annulus

Below are the properties applicable to each specific shape:

FlatPlate

• Height

• Width

• Thickness

• Angle

• Front

• Back

Cylinder

• Height

• SampleRadius

• CanRadius stands for the outer radius of the annular container, inner radius of which is the same as the radius of the sample.

Annulus

• Height

• CanInnerRadius

• SampleInnerRadius

• SampleOuterRadius

• CanOuterRadius
