引言磁聚焦、静电偏转(MS)系统(deflection)中电子光学的基本优点是有均匀的分辨率。这是由Schlesinger等人假定在均匀聚焦和偏转场工作条件(以下称为理想工作条件)下首先提出的。但是在有限的轴向长度的实际器件中这种均匀场是建立不起来的。Kubota等人研究了一种适用于非均匀场的实用设计方法。不管其意图如何,用于MS型摄象管的一种通用设计原则仍在研究中。由于在静电偏转系统中边界条件十分复杂,使三维电位的分析很困难,因此除了得到一些近似的计算以外,该管中的电位分布仍未解出。本文主要叙述了在实验的基础上获得高性能和小型坚固的管子的基本设计原则。本文也描述了正在研制的小型2/3英寸直径的硒砷碲摄象管中所获得的结果。该管和在标准电视体制中所用的传统1英寸摄象管具有几乎一样高的分辨率。文中也描述了一种具有特高分辨率的小型MS1英寸硒砷碲摄象管,它用于高分辨率电视。
Introduction Magnetic focusing, the fundamental advantage of electro-optic in electrostatic deflection (MS) systems, is the uniform resolution. This was first proposed by Schlesinger et al. Under the assumption of uniform focus and deflection field operating conditions (hereinafter referred to as ideal operating conditions). However, this uniform field can not be established in practical devices with finite axial length. Kubota et al. Studied a practical design method suitable for non-uniform fields. Regardless of its intent, a general design principle for the MS type video tube is still under study. Due to the complicated boundary conditions in the electrostatic deflection system, which makes the analysis of three-dimensional potentials difficult, the potential distribution in the tube remains unresolved, except for some approximate calculations. This article describes the basic design principles for obtaining high performance and small, robust pipes on an experimental basis. This article also describes the results obtained for a small 2/3 inch diameter selenium-arsenic tellurium imaging tube under development. The tube has almost the same high resolution as a conventional 1 inch video tube used in the standard television system. Also described is a very high resolution, small MS 1 inch selenium arsenide camera tube, which is used in high resolution television.
