NATURE OF THE INTERACTION BETWEEN ELECTRONS AND WELL-DEFINED SURFACESⅡ. Interaction Between a Small Cross-Section Helical Electron Beam and Uniform Electrical Fields Perpendicular to the Helical Axis

摘要

Analysis of the surface electrical field by a helical electron beam tangential to the surface requires knowledge of the beam trajectory, as well as an analysis of the beam deflection system used to instrumentally indicate this influence of the surface on the beam. This analysis has been made for a constant surface electrical field where the trajectory can be solved exactly. Constant deflecting fields of down to lμV volt can be analyzed with the experimental arrangement described in Part I of this report.
