后处理工艺中,U、Pu样品的分析比重大,分析点多,因此迫切需要选用方便快速的方法进行分析。L边密度计具有快速准确,无需预处理,非破坏性的特点,可以满足铀线和钚线中10～100g/L(如1AP、1BU等)左右样品的分析需要,大大提高工艺控制分析的效率。本工作建立了1台L边密度计原理性装置,由Spellman高压电源、45kV5mAX光管、25mm2Si-PIN探测器以及自行设计的光路组成。经过实验初步确定了L边测量的基本参数。设计了专用的
After-treatment process, U, Pu sample analysis of the large proportion of analysis points and more, so the urgent need to use a convenient and quick method of analysis. L-side density meter with fast and accurate, without pretreatment, non-destructive characteristics, uranium and plutonium lines to meet the 10 ~ 100g / L (such as 1AP, 1BU, etc.) about the sample analysis needs, greatly enhance the process control analysis effectiveness. This work has established a L edge density meter principle device, composed of Spellman high voltage power supply, 45kV5mAX light pipe, 25mm2Si-PIN detector and self-designed optical path. After the experiment initially determined the L side of the basic parameters of measurement. Designed for special
