Manually Modifying Geant4

(Necessary before Geant4 release Summer 2017)

In order to use the Davis LUT model Geant4 has to be extended. This documentation provides detailed step-by-step compiling instructions.

1. Follow compiling instructions here: Geant4 Installation stop before running ccmake, proceed with step 2.
2. Get the modified code and Look-up-Tables:

• 5 Geant4 classes to be replaced in Geant4 10.2 or 10.3, respectively]

  18 LUTs provided as a tar.gz archive to be downloaded here

1. Replace header files in your local Geant4 directory

   Go to /PATH_TO_yourGEANT4Directory/source/materials/include

   Replace the "G4SurfaceProperty.hh" file with the provided file

   Replace the "G4OpticalSurface.hh" file with the provided file

   Go to /PATH_TO_yourGEANT4Directory/source/materials/src

   Replace the "G4OpticalSurface.cc" file with the provided file

   Go to /PATH_TO_yourGEANT4Directory/source/processes/optical/include

   Replace the "G4OpBoundaryProcess.hh" file with the provided file

   Go to /PATH_TO_yourGEANT4Directory/source/processes/optical/src

   Replace the "G4OpBoundaryProcess.cc" file with the provided file

2. Open "G4OpticalSurface.hh" in /PATH_TO_yourGEANT4Directory/source/materials/include

   In line 270 set the path of the Davis_LUTs-folder that was downloaded in step 1

   G4String PathToLUT="/home/…/Davis_LUTs";

3. Go on with ccmake process in of step 1. and finish as documented.
4. To enable modifications of Geant4 in GATE: Follow compiling instructions: GATE V8.0 Installation

   In the ccmake process set CMake options GATE_USE_OPTICAL and GATE_USE_DAVIS to ON. (Run provided example to validate installation for LUT Davis model and compare to provided output file.)
