摘要：

A video-LEED system for rapid measurement of spin-polarized low-energy electron-diffraction (LEED) data is described. The system is based on a special, high-dynamic-range camera but will also support TV-rate cameras for less demanding I/V LEED work. The capabilities of the system include LEED pattern recording, and data acquisition for asymmetry versus energy (A/V), intensity versus energy (I/V), and intensity versus time (I/T). The design and operation of the system is described and illustrated by asymmetry data for W(001). © 1995 American Institute of Physics.
