The results of recent studies for the positron production in the crystal assisted radiator-converter approach (“hybrid solution”) are brief analysed for 10 ÷ 50 MeV electrons. Computer simulations have been performed for both coherent and incoherent bremsstrahlung in Si and Ge crystal radiators that successfully irradiate the W amorphous converter to release the electron-positron pairs. The positron stopping calculations in a thick convertor allow the optimal converter thickness for the maximum positron yield to be determined, and moreover, the energy spectra for emitted positron beams to be drawn for optimal converter thickness.
