We have converted a Philips thermionic emission electron microscope into a photoemission electron microscope by adding a simple ultraviolet illumination system, and a Channeltron Electron Multiplier Array (CEMA) for image intensification. This microscope provides photoemission images with or without heating of the sample, without removal of the surface oxide, and without activation. We illustrate with two examples: 1) a photoemission image of nickel, and 2) the first direct images of the exoelectron emission produced by abrasion of a metal surface.The microscope consists essentially of an electrostatic lens and two magnetic lenses. The immersion electrostatic lens is formed by the specimen, the Wehnelt cap at −15 kV, and the anode at ground potential.
