Magnetically confined electron beam system for high resolution electron transmission-beam experiments

7 pags., 7 figs.A novel experimental setup has been implemented to provide accurate electron scattering cross sections from molecules at low and intermediate impact energies (1-300 eV) by measuring the attenuation of a magnetically confined linear electron beam from a molecular target. High-resolution electron energy is achieved through confinement in a magnetic gas trap where electrons are cooled by successive collisions with N. Additionally, we developed and present a method to correct systematic errors arising from energy and angular resolution limitations. The accuracy of the entire measurement procedure is validated by comparing the N total scattering cross section in the considered energy range with benchmark values available in the literature.This study has partially been financed by the Spanish Ministry MINECO (Project No. FIS2016-80440).
