我们报告的设备的发展，使时间分辨光电子能谱的电荷运动的固体和结构化表面上的阿秒分辨率在超高真空环境中。该系统连接到帝国理工学院的阿秒光束线，允许用几个周期的近红外脉冲和阿秒脉冲序列探测表面上的电荷动力学和结构化表面上的等离子体场。该系统采用了新的隔振方法，以消除机械振动对样品和光学系统的振动耦合。一个孤立的阿秒脉冲也可以与一个多层XUV光学添加使用。本文提出了金中热电子布居的双光子光电子能谱测量方法。
We report the development of an apparatus to allow time resolved photoelectron spectroscopy of charge motion on solids and structured surfaces with attosecond resolution in an ultra high vacuum environment. The system, connected to the Attosecond Beamline at Imperial College, allows probing of charge dynamics on surfaces and plasmonic fields on structured surfaces with a few-cycle NIR pulse and attosecond pulse trains. The system incorporates novel methods of vibration isolation to eliminate vibrations coupling to sample and optics from mechanical vibrations. An isolated attosecond pulse can also be used with the addition of a multilayer XUV optic. A two-photon photoemission measure of a hot electron population in gold is presented.
