Abstract
We have designed and built a high-efficiency time-of-flight electron spectrometer which has the potential to record accurately the angular distribution of the photoemitted electrons. This analyzer uses an electrostatic analog of an optical parabolic mirror to collimate, in an isochronic fashion, half of the electrons emitted from an isotropic point source and measure each electron’s energy by time-of-flight. Results are presented which demonstrate that the spectrometer operates near its design collection efficiency and energy resolution.
