            Geant4 extended examples - channeling
        ----------------------------------------------

 Examples in this directory are dedicated to various coherent effects
 in oriented crystals, in particular, channeling, channeling radiation,
 coherent bremsstrahlung, coherent pair production etc. as well as their 
 various applications.

 ch0
 -------

 This example shows how channeling in bent crystal can be simulated
 in Geant4 using G4Channeling process. The example simulates the channeling 
 of 400 GeV/c protons in bent Si crystal. It has been moved into channeling/ch0 
 from the channeling folder.

 ch1
 -------
 
 This example is an easy demonstration of the minimum requirements necessary
 to integrate the G4ChannelingFastSimModel and the G4BaierKatkov model 
 into a project in order to simulate the physics of channeling and 
 channeling radiation/coherent bremsstrahlung.

 ch2
 -------
 
 This example is an enhanced version of ch1, providing the user with 
 the full functionality of both the G4ChannelingFastSimModel and G4BaierKatkov, 
 with parameters set up via a macro, in order to simulate the physics of 
 channeling and channeling radiation/coherent bremsstrahlung, and enhanced output.
 The example can be exploited for a wide range of cases to study coherent effects in
 a straight, bent or periodically bent crystal (crystalline undulator).

 ch3
 -------

 This example is an easy demonstration of the minimum requirements necessary
 to integrate the G4CoherentPairProduction process along with G4ChannelingFastSimModel 
 and G4BaierKatkov into a project in order to simulate the physics of electromagnetic
 shower in an oriented crystal. The simulation includes the physics of channeling, 
 channeling radiation/coherent bremsstrahlung and coherent pair production.
 The structure of this example is based on ch1, but with the G4CoherentPairProductionPhysics
 process included, as well as different output, a different crystal material, alignment and 
 geometry parameters, and a photon beam as the incoming source instead of charged particles.
