摘要:

本文研究了$10^{18}$ - $10^{20}$ ~W/cm $^2$激光与高Z靶相互作用中产生的正负电子对。计算结果的对生产和正电子产率从目标与津贴对生产过程中由于电子和韧致辐射光子的贡献。使用PRIZMA代码的蒙特卡罗模拟证实了所获得的估计。用功率为$10^2$ - $10^3$ ~TW的皮秒激光辐照高Z靶,其可能的正电子产额为$10^9$ - $10^{11}$。

英文摘要:

Electron-positron pairs' generation occuring in the interaction of $10^{18}$-$10^{20}$~W/cm$^2$ laser radiation with high-Z targets are examined. Computational results are presented for the pair production and the positron yield from the target with allowance for the contribution of pair production processes due to electrons and bremsstrahlung photons. Monte-Carlo simulations using the PRIZMA code confirm the estimates obtained. The possible positron yield from high-Z targets irradiated by picosecond lasers of power $10^2$-$10^3$~TW is estimated to be $10^9$-$10^{11}$.
