Measurement of Foam Density by X-ray Absorption Method

摘要: 文章介绍为适应惯性约束聚变(ICF)靶材料研究而发展的一种密度测量方法。通过测量X射线经靶材料吸收前后的强度变化,可较为精确地计算出待测样品的密度。用于泡沫材料密度测量的X射线源是特制的激发源。

Abstract: The paper concerns in a new simple method for measuring the density of foam used in ICF target.By measuring the variation of the X-ray count rate passing through the foam,the density of foam is precisely resolved.The X-ray source used in this experiment is particularly prepared.
