用蒙特卡罗程序FLUKA对两条新的后向康普顿散射激光电子光子束线进行了屏蔽设计，其中光子能量在NewSuBARU处高达76 MeV，在Spring8处高达2.9GeV。模拟了不同条件下光子束输运线和局部屏蔽体的泄漏剂量分布，以评估屏蔽元件在长束线上传输高能光子的效果。
Shielding design for two new laser electron photon beamlines using backward Compton scattering with the photon energy of up to 76 MeV at NewSUBARU and 2.9 GeV at SPring-8 have been performed by using the Monte Carlo code FLUKA with a modified user source code including the beam dumps which have double-layer and triple-layer structures, respectively. The leakage dose distributions depending on the various conditions of photon beam transport lines and local shields were simulated to estimate the effect of the shield components to transport high energy photons at long beamlines.
