A high-sensitivity angle and energy dispersive multichannel electron momentum spectrometer with simultaneous detection in 2π angle range is presented. A newly designed double half wedge and strip anode position-sensitive detector is employed to collect the ionized and scattered electrons passing through a 90° sector, 2π spherical electrostatic analyzer over azimuthal angle range of about 150° for each. Experimental results on argon are presented to exhibit the performance of the spectrometer.
介绍了一种在2π角范围内同时进行检测的高灵敏度角分辨和能量分辨多通道电子动量谱仪。采用新设计的双半楔形和条形阳极位置灵敏探测器来收集穿过90°扇形、2π球形静电分析仪的电离和散射电子,每个探测器在约150°的方位角范围内工作。给出了氩气的实验结果以展示该谱仪的性能。
