Formation of Low Reflectance Surface for Electrons and Measurement of Reflection Coefficient

Abstract

Low reflectance surface for electrons is formed using electrostatic flocking of carbon fiber piles. Carbon piles are vertically fixed on an aluminium plate by the epoxy resin mixed with carbon black. The reflection coefficient of the flocking surface is measured to be 0.2 in the energy range of 5-15eV. This value is about 50% compared to ordinaly metal (Al, Au, etc) surface. The reflection coefficient of flocking surface to electrons is lower than that of the surface covered with soot.
In this paper, we describe at first the formation method of flocking surface in briefly. And we also reports the result on the experiment for reflection coefficient at the surfaces include the flocking one.
