摘要：
Divergent X-ray radiation has been focused into a small spot (diameter 500 mum) by an X-ray lens made of polycapillaries, increasing the power density by 104 times. The new X-ray lens has been applied to the XRF technique. Limits of detection of 10(-9) - 10(-10) g have been obtained by means of the new technique with an X-ray tube of 2 W power.
