|---|
| 9 | --------------- |
|---|
| 10 | |
|---|
| 11 | N01 - Simple example to demonstrate how the GEANT4 basic framework works. |
|---|
| 12 | No physics involved, only tracking on a simple geometry. |
|---|
| 13 | N02 - Simulation of a simplified fixed target experiment. |
|---|
| 14 | Includes a simple parameterised geometry. Defines a transverse |
|---|
| 15 | uniform magnetic field. Include standard EM physics for gammas, |
|---|
| 16 | charged leptons and charged hadrons. Includes visualization and |
|---|
| 17 | detector response. |
|---|
| 18 | N03 - Simulation of a simple sample Calorimeter setup. |
|---|
| 19 | Shows the usage of 'replicated' volumes in the geometry. Defines |
|---|
| 20 | user commands for primaries generation (isotropic random distribution). |
|---|
| 21 | Defines a transverse uniform magnetic field. Include detector |
|---|
| 22 | response and statistics on relevant quantities. Include a tutorial |
|---|
| 23 | for visualization, exercising different visualization drivers. |
|---|
| 24 | N04 - Defines a simplified collider detector setup. |
|---|
| 25 | Demonstrates interfacing to the PYTHIA primary generator. Includes |
|---|
| 26 | the definition of a 'readout' geometry. Defines all ordinary physics |
|---|
| 27 | processes for leptons and hadrons. Exercises event filtering using |
|---|
| 28 | the stacking mechanism. Includes visualization. |
|---|
| 29 | N05 - Implements a setup for fast-parameterisation. |
|---|
| 30 | Provides a simple shower parameterisation for e+/e-/gamma in a |
|---|
| 31 | EM calorimeter, and a pi+/pi- parameterisation using ghost volumes. |
|---|
| 32 | Implements parameterised detector response. |
|---|
| 33 | N06 - Simulation of optical photons generation and transport. |
|---|
| 34 | Defines optical surfaces and exercises optical physics processes |
|---|
| 35 | (Cerenkov, Scintillation, Absorption, Rayleigh, ...). Uses stacking |
|---|
| 36 | mechanism to count the secondary particles generated. |
|---|
| 37 | N07 - Implements three simplified sandwitch calorimeters. |
|---|
| 38 | Shows how to modify part of the geometry setup at run-time. Includes |
|---|
| 39 | detector description parameterisation by materials. Demonstrates |
|---|
| 40 | sharing of a sensitive detector definition for different sub-detectors. |
|---|
| 41 | Defines different geometrical regions with different production |
|---|
| 42 | thresholds. Shows customization of the G4Run. |
