Abstract Time-of-flight spectrometer configurations combined with position sensitive single particle counting detectors have been simulated with a Monte Carlo code to find an efficient solution for coincident low energy electron detection. Photoemission experiments on polycrystalline silver have been performed at a synchrotron radiation facility with a likewise wide-angle ARPES (angle resolved photoemission spectroscopy) setup. Low-energy electron pairs created from secondary electron emission have been detected in coincidence obtaining their full momentum vectors.

飞行时间光谱仪，用于从具有 2π 立体角、对识别和无限带路径 (2e2πCS) 的表面高效重合检测低能电子

摘要 飞行时间光谱仪配置与位置敏感的单粒子计数探测器相结合，已经用蒙特卡罗代码进行了模拟，以找到重合低能电子检测的有效解决方案。已在具有同样广角 ARPES（角分辨光发射光谱）装置的同步加速器辐射设施中对多晶银进行了光发射实验。已检测到由二次电子发射产生的低能电子对，同时获得了它们的完整动量向量。
