Channeling radiation relation with the mean number of channeled particles
Abstract
We considered planar positron channeling in {110} planes in Silicon. We used the appropriate FokkerPlanck type kinetic equation to calculated the values of the flux distribution function at several depths for the energies of 1 GeV, 5 GeV and 10 GeV and incidence angles 0, 0.5 Ψ_{L}, and 0.8 Ψ_{L}, where Ψ_{L} is the Lindhard angle. Using the values of the flux distribution function at the critical transverse energy, we calculated the mean number of particles with transverse energies equal to the critical one. The first maximum of the radiation intensity is proportional to this number. We conclude that the first maximum of the radiation intensity versus particle is expected to decrease dramatically with increasing depth.
