摘要
复合光导管组成的Ｘ光透镜可将发散的Ｘ光束聚至直径φ０．５ｍｍ，聚束后的功率密度增加１０４倍．这种新型的Ｘ光透镜已用于Ｘ射线荧光分析研究，使用Ｘ光管功率仅２Ｗ，而探测限可达１０－９—１０－１０ｇ．
Divergent X-ray radiation has been focused into a small spot(φ500μm) by an X-ray lens made of polycapillaries, increasing power density by 104 times. The new X-ray lens has been applied to the XRF analysis. The detection limits of 10-9-10-10g have been obtained by means of the new technique with a 2W X-ray tube.
