0003 ## Geometry and SD
0004
0005 This example uses mass geometry to create the main volume (homogeneous material) and use it
0006 as an envelope for the parametrisation, but the readout geometry (crystals)
0007 are defined in the parallel geometry, together with the sensitive detector
0008 to store the hits.
0009 Geometry and sensitive detector are defined in:
0010 - ExGflash3DetectorConstruction
0011 - ExGflash3ParallelWorld
0012 - ExGflash3SensitiveDetector
0013
0014 ## Details of implementation:
0015
0016 - ExGflash3.cc:
0017 Parallel world needs to be registered;
0018 Physics of the parallel world needs to be registered so sensitive detector can
0019 collect hits;
0020 Fast simulation is activated for mass world (where envelope is);
0021
0022 - ExGflash3DetectorConstruction:
0023 Only main volume (box) with material is created;
0024 Creation of G4Region associated to G4LogicalVolume of that box;
0025 Initialization of GFlash, attaching it to the envelope (G4Region);
0026
0027 - ExGflash3ParallelWorld:
0028 Construction of identical volume for the main box as in the mass geometry,
0029 but with dummy material (it is not used anyway);
0030 Construction of individual crystals for the readout geometry;
0031 Creation of the sensitive detector;
0032
0033 - ExGflash3SensitiveDetector:
0034 Uses pointer to ExGflash3DetectorConstruction to get the crystals for the readout;
0035
0036 ## Macros
0037
0038 - vis.mac - macro for use in interactive mode (default, if no arguments are specified)
0039 - test.mac - macro for tests: 50 GeV electrons are shot in the direction of the detector
0040 (along z axis), 10 times. As they enter the parametrisation envelope,
0041 the GFlash parametrisation is invoked and energy is deposited.
0042 The results are printed out:
0043 - energy in the most central crystal
0044 - energy in 3x3 crystals
0045 - energy in 5x5 crystals
0046 - number of created deposits
0047 - simulation time per event
