Abstract: | A technique for calculating the frequency and polarization of the coherent bremsstrahlung from relativistic electrons in single crystals of arbitrary thickness is proposed and implemented. It accurately includes multiple scattering of the emitting particles and the angular distribution and collimation of the radiation. The spectral properties of the collimated beam of radiation from electrons with energies of 900 MeV in thick ( 0.1 r.l.) single crystals of diamond, silicon, and tungsten are compared with the calculations. When the radiation is tightly collimated the dependence of the frequency and polarization properties of the radiation on the multiple scattering of the emitting particles in the crystals becomes weaker.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 6, pp. 21–43, June, 1991. |
