Abstract

By combining the simulation program 4D-MCLCSS of laser Compton scattering and the package of Geant4

the gamma rays generation of Shanghai laser-electron gamma source and its impact on the photo-transmutation process of the long-lived fission products

126

Sn was simulated. The dependency of transmutation ratio and the geometry parameters of transmutation target was researched

and the transmutation product distribution based on SLEGS was initially diagnosed. It is shown that the best target thickness and the best radius to obtain the transmutation target of

126

Sn are respectively 16 cm and 0.4cm

and the corresponding transmutation rate is 1.8910

/s. The research results show that the light photo-transmutation rate based on SLEGS is twice higher than the laser-driven bremsstrahlung

and its upgrade potential is huge.
