  4. 4. Implementation of the Detector-Construction of our application
    Alvaro Tolosa-Delgado (CERN)
    19/05/2026, 15:50

    We will develop the main of our application.
    Then we will start to implement its mandatory components:
    - first the DetectorConstruction, i.e. the detector geometry and material description

    We will revisit the key Geant4 concepts (run, event, step) related to actions

    Introduce of the Actions and the related Geant4 interfaces
    - Stepping Action (G4UserSteppingAction),
    - Event Action (G4UserEventAction),
    - and RunAction G4UserRunAction,

    Implement the remaining user actions of our application.
