我们描述了一种新的光谱显微镜装置--NanoESCA@Elettra--的首次经验，该装置已经安装在Elettra(的里雅斯特)的纳米光谱软X射线光束线上。该系统的特点是一个带有30千伏浸没透镜系统的能量过滤光电子显微镜和一个双半球能量分析仪。该仪器提供实空间和k空间两种映射模式。利用实验室气体放电源对纳米结构样品进行的实验表明，其横向分辨率小于50 nm，能量分辨率优于200 meV。我们还用同步辐射对仪器进行了第一次测试。[doi：10.1380/ejssnt.2011.395]
We describe first experiences with a novel spectromicroscopy set-up — NanoESCA@Elettra — which has been installed at the nanospectroscopy soft x-ray beamline at Elettra (Trieste). The system features an energy-filtered photoemission microscope with a 30 kV immersion lens system and a double-hemispherical energy analyzer. The instrument provides both real space and k-space mapping modes. Experiments on nanostructured samples with laboratory gas discharge sources show a lateral resolution of less than 50 nm and an energy resolution of better than 200 meV. We have also performed first tests of the instrument with synchrotron radiation. [DOI: 10.1380/ejssnt.2011.395]
