\page Examples_channeling Category "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.
\ref Examplech0
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.
\ref Examplech1
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.
\ref Examplech2
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).
\ref Examplech3
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.
\ref Examplech5
Example ch5 is an application for simulating a positron source. Although the conventional approach based on an amorphous target is possible, the application is primarily designed to simulate positrons based on oriented crystals. In the latter case, both the single-crystal and the hybrid scheme can be investigated.
