Abstract : Work function differences on polycrystalline tungsten are studied extensively by means of electron mirror microscopy. The Electron Mirror Microscope (EMM) is shown to be a sensitive tool for correlating cesium adsorption with surface defects. EMM image formation is discussed qualitatively. The instrument response to potential gradients was quantitatively measured as a function of EMM parameters. (Author)
