摘要：
The paper presents numerically calculated models of new electrostatic energy analyzers based on a conical facefield, which is restricted by concentric cylindrical (inner) and truncated-cone (outer) electrodes and two flat boundaries, perpendicular to the axis of symmetry. The calculated analyzers show good enough as energy resolution as well the acceptance characteristics, simple design ( without fringing fields) and provide wide abilities for analyzing surfaces of remote objects of different shape and size. Remote sensing allows use in various applications when is desirable to use a set of methods without mutual interference, what is useful tool's characteristic for investigating nanostructures.
