Abstract
Methodology is developed that incorporates the radiation reaction force into the relativistic molecular dynamics framework implemented in the MBN Explorer software package. The force leads to a gradual decrease in the projectile's energy E due to the radiation emission. This effect is especially strong for ultra-relativistic projectiles passing through oriented crystals where they experience the action of strong electrostatic fields as has been shown in recent experiments. A case study has been carried out for the initial approbation of the methodology developed. Simulations of the processes of planar channeling and photon emission have been performed for 150 GeV positrons in a 200 microns thick single oriented Si(110) crystal. Several regimes for the decrease in E have been established and characterized. Further steps in developing the code to include the necessary quantum corrections are identified and possible algorithmic modifications are proposed.
