Day 2 - Exercise Geant4 Materials

Geant4 and Calorimetry in HEP

OBJECTIVE

Learn how to create and use a materials

HOW

In this exercise you will be asked to create the material used for the electromagnetic calorimeter of the exercise. The relevant method to look at is in DetectorConstruction::DefineMaterials()

Look at the code there in file src/DetectorConstruction.cc , the line

G4cout<<*(G4Material::GetMaterialTable()) <<G4endl;

added at the end of the function prints the list of known materials.

PRACTICE

Hint - Deactivate Qt UI

Activate the vanilla Geant4 interface for this exercise.
	% unset G4UI_USE_QT
        % unset G4UI_USE_XM
as we are mainly looking to the text output.
