偏转灵敏度与电子枪直径之间的决择问题是每个 (?)KT 设计人员所共知的。解决这种难题的实用偏转系统已研制成功。为了获得高分辨率的液晶彩色光栅,这种缩径系统由一个安装在漏斗(?) CRT 管颈上的22.5mm 李兹线鞍状环形线圈组成,这样可以允许应用较大直径的电子枪。该系统有高偏转灵敏度和高分辫率的特点.本文也给出了有关偏转线圈功耗的描述。 The issue of the choice between deflection sensitivity and electron gun diameter is well known to every (?) KT designer. A practical deflection system to solve this problem has been developed. In order to obtain a high resolution liquid crystal color grating, this diameter reduction system consists of a 22.5 mm Litz wire saddle-shaped loop coil mounted on the neck of a funnel (?) CRT, which allows the use of larger diameter electron guns. The system has the characteristics of high deflection sensitivity and high braid rate.The paper also gives a description of the deflection coil power dissipation.
