| 摘 要： | 本文从实验角度对合肥国家同步辐射实验室软X射线束的空间相干性进行了研究.利用放置在物面上的高分辨正性光刻胶,记录了中心波长为3.2nm的波带片和针孔直径为30μm组合的光场分布(光斑),获得相应条件下的爱里斑及空间相干直径实验数据;完成了一个双缝干涉实验.所得的这些结果与理论计算相一致.

| Abstract: | Experimental study on spatial coherence of soft X-ray beam from Hefei synchrotron radiation source has been carried out.A spot,that is distribution of optical field,was recorded by positive photoresist (PMMA) located at object plane under the condition of a condenser zone plate which center wavelength is 3.2nm and a pinhole of 30μm diameter combination.The diameters of Airy diffraction pattern and spatial coherence area were obtained from the spot.In addition,a double slit interference experiment has also been carried out.These experiments are in a good agreement with the calculation estimates. |
