Rapid, pulse counting low-energy electron diffraction instrument
Abstract
A low-energy electron diffraction instrument has been constructed which allows one to visually observe a LEED pattern, record the pattern photographically and obtain immediate, quantitative intensity data from several diffraction beams in 5-10 s. The instrument operates at incident beam currents of a few picoamperes eliminating electron beam damage effects. This paper describes the design and construction of this new LEED instrument and reports on the operating parameters of sensitivity, signal-to-noise, image distortion, and angular resolution.
