Abstract: Using method of the field desorption microscopy, desorption of cesium atoms from quasi-spherical surface of a rhenium microcrystal in the electric field has been investigated. The dependence of the desorbing electric field strength vs cesium coverage of the surface has been obtained. In the framework of the image force model for the field desorption, the heat of adsorption of cesium atoms in dependence on the surface concentration of cesium and the work function of the surface has been evaluated.
Keywords: field desorption microscopy, ion sources, field emitter, rhenium, alkaline metals.
