Study on Focusing Lens System In Modulation Type Quasi-laminar Flow Electron Gun
调制型准层流电子枪聚焦透镜系统的研究

Based on the operating principle of image converter tubes,an analysis of the disadvantageous effect of the existing electron beam cross-over section on its overall performance was made.The emphasized consideration of performance optimization means that it is necessary to adopt the quasi-laminar flow electron gun.A basic analytical model of optimized system of focusing electron lens is well established through the comparative analysis on the deficiency of focusing performance of the commonly used electrostat...
