摘　　要：为在百千焦耳装置集束验证平台上开展LPI实验研究,建设了基于集束模式的散射光诊断系统。该诊断系统使用大口径漫反射板作为主要拦光、反射、取样元部件,利用成像方式将漫反射板分别成像至门控相机等记录部件,采取取样测量方式得到散射光空间分布、能量大小及光谱等参量。在集束首轮物理实验中,该系统获得了较完备的物理数据。For the sake of carrying out the laser plasma interaction(LPI)experimental research on the cluster testing platform of the hundred kilojoule laser facility,a backscattered light diagnostic system based on the cluster mode is constructed.The diagnostic system uses several large aperture diffuse plates as the main light blocking,reflecting and sampling components.The diffuse plates are then imaged to the gating camera and other recording components by imaging the integral data in a proper gate time.The spatial distribution,energy and spectrum of backscattered light are obtained by sampling measurement.In the first round of cluster physics experiment,the system has obtained relatively complete physical data.
