  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

  5. 5. Completing the Detector-Construction implementation
    Alvaro Tolosa-Delgado (CERN)
    20/05/2026, 14:00

    We start work today using the end-of-day2.tar.gz which you will find in Day2 (first presentation).

    Please read its README.txt file to get started.

    20/05/2026, 15:50

    Topics:
    - a (very basic) look behind multi-threaded Geant4
    - introduction of the G4VUserPrimaryGeneratorAction and usage
    - introduction of G4VUserActionInitialization interface
    - implementation of the primary generator of our application

  8. 8. Introduction of more Geant4 user actions
    Alvaro Tolosa-Delgado (CERN)
    21/05/2026, 15:50

    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.
