Abstract

The first observation of a true geometrical focus of X-rays well beyond the exit of a paraboloidally tapered glass monocapillary is reported. An intensity gain of 250 +/- 20 into a 6 x 9 mum pinhole for 8 keV X-rays and transmission efficiencies of more than 90% below 20 keV were observed.

摘要

首次报道了在抛物面锥形玻璃单毛细管出口之外观察到X射线真正的几何焦点。对于8keV的X射线，在一个6×9微米的针孔中观察到强度增益为250±20，并且在20keV以下观察到传输效率超过90%。
