在电工实验室强慢正电子束流线上建立了高分辨率正电子湮灭诱导俄歇电子能谱仪。该系统使用短脉冲正电子束（~ ns宽度）和飞行时间（TOF）方法对俄歇电子进行能量分析。为了提高能量分辨率，在样品和检测器之间安装一个电隔离的飞行管，并通过偏置飞行管来延迟电子。该方法使高分辨率PAES光谱的高效测量成为可能。
An apparatus for high-resolution positron-annihilation induced Auger electron spectroscopy (PAES) has been constructed at the intense slow positron beam line of the Electrotechnical Laboratory. The system uses a short pulsed positron beam (∼ ns width) and the time-of-flight (TOF) method for the energy analysis of the Auger electrons. In order to improve the energy resolution, an electrically isolated flight-tube is installed between a sample and a detector, and the electrons are retarded by biasing the flight tube. This method makes it possible to measure high-resolution PAES spectra with high efficiency.
