GDML DETECTOR SENSITIVITY

This example demonstrates the usage of the GDML auxiliary information for associating a sensitive detector to a volume.

The detector construction consists of a call to GDMLProcessor which parses a GDML file and returns the pointer to the world volume. The user can also write her/his own GDML file and use it as the primary input format for her/his Geant4 application.

A simple GDML files is provided:

• auxiliary.gdml, showing association of a volume with the auxiliary information, related to the sensitive detector.

HOW TO BUILD THE EXAMPLE ?

• You need to have built the persistency/gdml module by having set the -DGEANT4_USE_GDML=ON flag during the CMAKE configuration step, as well as the -DXERCESC_ROOT_DIR=path_to_xercesc flag pointing to the path where the XercesC XML parser package is installed in your system.

• Compile and link to generate the executable (in your CMAKE build directory):

% make

• Execute the application for parsing interactively the GDML file:

% ./gdml_det auxiliary.gdml
