0002 Geant4 extended examples - channeling
0003 ----------------------------------------------
0004
0005 Examples in this directory are dedicated to various coherent effects
0006 in oriented crystals, in particular, channeling, channeling radiation,
0007 coherent bremsstrahlung, coherent pair production etc. as well as their
0008 various applications.
0009
0010 ch0
0011 -------
0012
0013 This example shows how channeling in bent crystal can be simulated
0014 in Geant4 using G4Channeling process. The example simulates the channeling
0015 of 400 GeV/c protons in bent Si crystal. It has been moved into channeling/ch0
0016 from the channeling folder.
0017
0018 ch1
0019 -------
0020
0021 This example is an easy demonstration of the minimum requirements necessary
0022 to integrate the G4ChannelingFastSimModel and the G4BaierKatkov model
0023 into a project in order to simulate the physics of channeling and
0024 channeling radiation/coherent bremsstrahlung.
0025
0026 ch2
0027 -------
0028
0029 This example is an enhanced version of ch1, providing the user with
0030 the full functionality of both the G4ChannelingFastSimModel and G4BaierKatkov,
0031 with parameters set up via a macro, in order to simulate the physics of
0032 channeling and channeling radiation/coherent bremsstrahlung, and enhanced output.
0033 The example can be exploited for a wide range of cases to study coherent effects in
0034 a straight, bent or periodically bent crystal (crystalline undulator).
0035
0036 ch3
0037 -------
0038
0039 This example is an easy demonstration of the minimum requirements necessary
0040 to integrate the G4CoherentPairProduction process along with G4ChannelingFastSimModel
0041 and G4BaierKatkov into a project in order to simulate the physics of electromagnetic
0042 shower in an oriented crystal. The simulation includes the physics of channeling,
0043 channeling radiation/coherent bremsstrahlung and coherent pair production.
0044 The structure of this example is based on ch1, but with the G4CoherentPairProductionPhysics
0045 process included, as well as different output, a different crystal material, alignment and
0046 geometry parameters, and a photon beam as the incoming source instead of charged particles.
