| Popis: | The detailed study of the secondary electron yield of technical surfaces for very low electron landing energies (LE-SEY) is a very important parameter to be taken into account to ensure the correct operation of particle accelerators. Despite such interest, LE-SEY (0-30eV) curve has been rarely addressed due to the intrinsic experimental complexity to control very low energy electrons. In this paper, we present an experimental SEY and LE-SEY study carried out on a number of materials of interest for multipacting and electron cloud (e-cloud) mitigation. We also compare here the SEY curves of clean polycrystalline noble metals with those measured on their technical surface.
