滤波差分法测量软X射线谱

MEASURMENT OF SOFT X\|RAY SPECTRUM BY FILTER DIFFERENCE METHOD 

研究一种测量激光等离子体发射软Ｘ射线谱强度的新方法———滤波差分法．介绍了滤波差分法基本原理，给出了滤波差分对的理论计算结果及实验测量结果，并用此方法获得软Ｘ 射线谱的绝对强度。

The method of filter difference,which is used to measure X\|ray spectrum radiated from laser\|produced plasma,has been studied in this paper.The basic principle of the method of filter difference is introduced and the calculated and measured results of filter difference pair are given.The absolute soft X\|ray spectra from laser plasma have been measured.Finally,the errors of measured spectrum intensity are analysed and estimated.
