Computer simulation of electron-positron pair production by channeling radiation in amorphous converter

Abstract

We consider the radiator-converter approach at 200 MeV channeled electrons (the SPARC-LAB LNF facility energies) for the case of using W crystalline radiator and W amorphous converter. A comparison of the positron production by the axial channeling radiation and the bremsstrahlung is performed. The positron stopping in the convertor is studied by means of computer simulations. It is shown that for the maximum yield of positrons the thickness of the W amorphous converter should be taken 0.35 cm in the case of using the axial channeling radiation resulting to total yield of positrons 5 10^-3 e⁺/e^- and 0.71 cm in the case of using the bremsstrahlung resulting to total yield of positrons 3.3 10^-3 e⁺/e^-.
