高反射效率高定向性的热解石墨晶体X射线谱仪
A high efficiency highly oriented pyrolitic graphite X-ray sp ectrometer
摘要
Abstract
A novel design of X-ray spectrometer is implemented, using a high efficiency HOPG (highly oriented pyrolitic graphite) Bragg crystal. The spectral resolution of it can reach above 350 with energy ranging from 6.891 to 9.193 keV, theoretically. And the efficiency are 3 order of magnitude higher than the ordinary X-ray crystal spectrometer. Application of this instrument is demonstrated in high intensity laser-foil interaction experiments. It is shown that HOPG spectrometer has much lower threshold of X-ray intensity than ordinary one. The spectral resolution for 8.048 keV (Cu Kα-line) can reach 40 eV, which gives the spectral resolution greater than 200.关键词
