0040  * @brief Detector construction.
0041  *
0042  * Creates a cylindrical detector, with cylinder axis along Z-axis. It is placed
0043  * in the world volume so that its bases are located at z=0 and z=Length.
0044  * Dimensions of the detector (Radius and Length) and material can be set using
0045  * the UI commands.
0046  * Readout geometry of the detector is created, and can be set by UI commands.
0047  * Cells are created along z-axis, azimuthal angle, and radius (cylindrical
0048  * segmentation).
0049  * Sensitive detector Par03SensitiveDetector is attached to the
0050  * cell volume.
0051  * Region for the detector is created as an envelope of the fast simulation.
