摘要
基于由同心环状排布的多个PIN探测器组成的环状PIN阵列,发展了一种测量激光等离子体全口径背向散射光空间分布的实验方法。采用该方法,在神光Ⅱ装置激光与黑腔靶相互作用实验中,对全口径背向散射光空间分布进行了测量,获得了全口径受激Brillouin散射背向散射光空间分布的图像。初步建立了全口径背向散射光空间分布的测量方法。
The spatial distribution of backscatter light is very important for understanding the production of backscatter light. The experimental method of spatial distribution of full aperture backscatter light is based on the circular PIN array composed of concentric orbicular multi-PIN detectors. The image of backscatter light spatial distribution of full aperture SBS is obtained by measuring spatial distribution of full aperture backscatter light using the method in the experiment of laser hohlraum targets interaction at ＂shenguang II＂. A preliminary method to measure spatial distribution of full aperture backscatter light is established
