A dynamic beam propagation model of micro-vibrating spatial filters in inertial confinement fusion(ICF) facilities is built based on the additional beam in SG-II facility.The transfer matrix is then deduced,and the sensitivities of the beam positioning to the pellet in the target area to the vibrations of every spatial filter are analyzed,which indicates that the vibrations of spatial filters in the pre-amplify zone has less effects on beam positioning stability at the target.In addition,the vibrations of spatial filters in the main amplify zone dominates the beam positioning stability of the target,especially the vibration of the spatial filter SF7. 相似文献

本文以壳聚糖单体为碳源兼凝胶剂,利用溶胶-凝胶煅烧合成了锂离子电池LiFePO4/C正极材料,使用XRD和SEM对合成的材料进行表征. 用恒电流充放电测试了LiFePO4/C电极的电化学性能,当壳聚糖单体与LiFePO4摩尔比为1:1.2时,600 oC煅烧的LiFePO4/C电极性能最佳,其粒径分布均匀(200 ~ 400 nm),该电极0.2C倍率放电比容量为155 mAh.g-1,30周期循环放电比容量仍保持152 mAh.g-1,库仑效率为97.9 %. 相似文献
