Abstract
The design, simulation, and construction of an electron impact spectrometer for coincident detection of both outgoing electrons in an electron impact ionization, (e,2e) experiment, is described. The spectrometer is a relatively conventional electrostatic-based design which consists of an electron gun, two 180° hemispherical analyzers, a Faraday cup, and an optional photon detector for possible triple coincidence experiments. An electron ray-tracing simulation program, SIMION, is used to predict characteristics of the gun and analyzer along with several multi-element electrostatic lenses. A full description of the spectrometer layout, its working principle and the expected behavior obtained by computer simulations are presented.
