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
6
/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.
