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.

在具有10÷5 MeV电子的晶体辅助正电子源上

对于10÷50 MeV电子，简要分析了晶体辅助辐射转换器方法（“混合溶液”）中正电子生产的最新研究结果。已经对成功地辐照了W非晶态转换器以释放电子-正电子对的Si和Ge晶体辐射体中的相干和非相干致辐射进行了计算机模拟。厚转换器中的正电子停止计算可以确定最大正电子产量的最佳转换器厚度，此外，可以为最佳转换器厚度绘制发射正电子束的能谱。
