论文摘要
在PAL-XFEL设施上进行了基于二阶相关性的汉伯里·布朗和Twiss干涉测量实验。在该实验中研究了X射线辐射的统计特性。在各种操作条件下，在NCI光束线上以10 keV光子能量进行测量：分别在120 pc，180 pc和200 pc电子束电荷的自发自发发射（SASE），带有单色的SASE和自种群。统计分析表明，根据操作条件，平均脉冲持续时间为6 fs至9 fs。在空间域中，在空间结构域中，用单色和自种操作方案确定了高空间相干性约为70-80％。获得的值描述了在PAL-XFEL设施上生成的梁的统计特性。
Hanbury Brown and Twiss interferometry experiment based on second-order correlations was performed at PAL-XFEL facility. The statistical properties of the X-ray radiation were studied within this experiment. Measurements were performed at NCI beamline at 10 keV photon energy in various operation conditions: Self-Amplified Spontaneous Emission (SASE), SASE with a monochromator, and self-seeding regimes at 120 pC, 180 pC, and 200 pC electron bunch charge, respectively. Statistical analysis showed short average pulse duration from 6 fs to 9 fs depending on operation conditions. A high spatial degree of coherence of about 70-80% was determined in spatial domain for the SASE beams with the monochromator and self-seeding regime of operation. The obtained values describe the statistical properties of the beams generated at PAL-XFEL facility.
