Abstract
A multiple-angle, parallel detection scheme for ultraviolet photoemission spectroscopy and LEED has been developed based on a minicomputer-controlled vidicon camera and a LEED-grid energy analyzer. This system allows rapid data acquisition and display so that one can obtain energy spectra over a 70 degrees x70 degrees collection geometry with +/-1.5 degrees resolution in 30-40 min, or collect the intensities of all visible LEED beams in a few seconds. This is nearly two orders of magnitude faster than a conventional movable single-detector system. Operating principles and design limitations will be discussed.Keywords
