摘要：
This letter presents a method for digitizing the collector signal of a LEED-optics system, used in the retarding field analyser mode. The transformation of a current into a digital signal with a sufficient dynamic range and the modifications needed for the reduction of noise are discussed. The performance of such a system is tested on a three-grid LEED-Auger retarding field analyser having an energy resolution of ΔE/E = 2.5%. As an example, Auger spectra of aluminium films on a carbon substrate are shown. © 1990.
