47 * @brief Sensitive detector.
48 *
49 * Describes how to store the energy deposited within the detector.
50 * It derives from two classes: G4VSensitiveDetector and
51 * G4VFastSimSensitiveDetector. Addition of G4VFastSimSensitiveDetector is
52 * necessary in order to handle the energy deposits from the fast simulation.
53 *
54 * Two ProcessHits() methods are introduced to handle energy deposited from full
55 * (detailed) simulation, and from fast simulation. The common part is handled
56 * by RetrieveAdnSetupHit() method.
