37 * @brief Detector construction.
38 *
39 * Creates a cylindrical detector, with cylinder axis along Z-axis. It is placed
40 * in the world volume so that its bases are located at z=0 and z=Length.
41 * Dimensions of the detector (Radius and Length) and material can be set using
42 * the UI commands.
43 * Readout geometry of the detector is created, and can be set by UI commands.
44 * Cells are created along z-axis, azimuthal angle, and radius (cylindrical
45 * segmentation).
46 * Sensitive detector Par03SensitiveDetector is attached to the
47 * cell volume.
48 * Region for the detector is created as an envelope of the fast simulation.
