0007 Electron beam of 50 MeV converted on target. All charged particles removed
0008 from the beam after the target. Gamma beam irradiate a water phantom.
0009 In front of the phantom a thin CheckVolume is placed to score gamma
0010 beam properties. Inside the phantom a score volume is placed to calculate
0011 radial radiation dose distribution.

0014 ## GEOMETRY
0015
0016
0017 GammaTherapy application geometry consists of along z:
0018
0019 -# Generator of electrons directed along z-axis
0020 -# Target1 (Be, W)
0021 -# Target2 (W, Cu)
0022 -# GasVolume (He) : all charged particles are killed inside
0023 -# CheckVolume (Air) : is sensitive for scoring in front of thephantom
0024 -# Phantom (H2O) : is sensitive for radioactive dose calculation
0025 -# Absorber in Phantom (H2O) : is sensitive for transverse dose calculation
0026
0027 World volume consists of Air.

0029 ## STEERING
0030
0031 Geometry and other parameters can be defined by G4 UI commands.
0032
0033 Following macro files are prepared for different targets used in the real
0034 setup: be.in (thin Be target), be_w.in (thick BeW target), cu_w.in (thick
0035 Cu W target).
0036
0037 Only Physics Lists from physics_list kernal library can be activated.
0038 Corresponding UI commands are following
0039
0040 ```
0041 /testem/phys/addPhysics emstandard
0042 /testem/phys/addPhysics emstandard_opt3
0043 /testem/phys/addPhysics empenelope
0044 /testem/phys/addPhysics emlivermore
0045 ```
0046
0047 The vis.mac file can be used as an example of visualization.
