摘要

介绍了一种具有压缩片电子束和场发射阴极的电子光学系统的设计和仿真结果。在线性压缩~ 10下对电子枪进行建模，得到电流为0.1A的电子束尺寸为0.125·0.7mm2。阴极处电场为0.4·105 V/cm，阳极电压为20000 V。讨论了由场发射阴极组成的电子枪获得高密度片束聚焦的可行性。

Synthesis of a Sheet Beam Electron Optical System with a Field Emission Cathode

The results of design and simulation of an electron-optical system with compression sheet electron beam and field emission cathode are presented. The result of modeling the electron gun at linear compression ∼ 10, the beam of current 0.1A has the size of 0.125·0.7mm2 are performed. The electric field at the cathode is 0.4·105 V/cm at anode voltage 20000 V. The feasibility of obtaining a high density sheet beam focusing of electron gun consisting of field emission cathode is discussed.
