Today's exercises cover the following items:
A Geant4 application example is provided, which serves as basis of the exercises. The exercises include the modification and/or extension of the following classes:
Exercise 2-1
Get familiar with the classes of the example application, that correspond to the
topic of the exercises (see the list above).
The following diagram shows the class hierarchy of the detector (click here for a pdf file):
The class hierarchy of the primary generator is shown in the second diagram (click here for a pdf file):
Answer the following questions:
Exercise 2-2
In the class DetectorConstruction.cc define the following G4Isotopes (stable isotopes of
germanium); then define a G4Element, which is germanium enriched in Ge-76. This material is
used for neutrinoless double-beta decay experiments.
Exercise 2-3
Exercise 2-4
Exercise 2-5
Exercise 2-6
In the default case, the primary particle is a 1-MeV electron impinging perpendicularly on a side of the detector
box. The impinging angle can be changed interactively by the command /source/incidentAngle
Exercise 2-7
Remove the code produced within the previous exercise, and replace the "pencil beam" defined by default
with a isotropic point source.
Exercise 2-8
Generate a point source, as before, emitting gamma-rays of 122 keV (branching ratio: 86%) and 136 keV
(branching ratio: 14%)
