Detector Construction and Messenger

• B2aDetectorConstruction.hh: This header typically defines the construction of the detector geometry. It sets up the various components of a detector, including volumes and materials.
• B2aDetectorMessenger.hh: This file usually contains commands for interacting with the detector construction from a user interface, allowing dynamic changes to parameters during a simulation.

Sensitive Detectors

• B2TrackerSD.hh: This header defines a sensitive detector class, which is responsible for recording hits (interactions) within a specific volume of the detector.

Material Management

• G4Material.hh: This class represents materials in Geant4. It allows users to define properties such as density, state (solid, liquid, gas), and composition.
• G4NistManager.hh: A utility class that provides access to a predefined database of materials based on NIST data. It simplifies the process of defining common materials by allowing users to retrieve them easily.
• G4SDManager.hh: This class manages sensitive detectors and their associated hits. It allows for the registration and handling of sensitive detector classes.

Geometry Classes

• G4Box.hh: Defines a box-shaped volume in the simulation. It is often used to represent simple geometric shapes.
• G4Tubs.hh: Represents a cylindrical volume (tube) in the simulation, useful for modeling cylindrical detectors or components.
