我们研制了一种平面屏幕,高偏转灵敏度的示波管,管的外形如图1所示.该管为静电聚焦、静电偏转和一次后加速式的,与国内目前使用的苏型13ЛО37示波管一样.在外形尺寸、电极引线排列位置和使用条件等方面也完全同于后者,因而具有很大的通用性.由浸没物镜、单透镜组合的,第一阳极零电流的电子枪与偏转系统所构成的电子光学系统如图2.电子枪圆筒状加速极中小孔径(φ1.2毫米)膜片的应用是获得细光点的重要保证之一.电子枪全长(约为
We have developed a flat screen, high deflection sensitivity of the oscilloscope tube, the tube shape shown in Figure 1. The tube for electrostatic focusing, electrostatic deflection and a post-acceleration, and the current use of the Soviet-type 13ЛО37 oscilloscope Tube in the same size, electrode lead arrangement position and conditions of use are also exactly the same with the latter, which has great versatility by submerged objective lens, single lens combination, the first anode zero current electron gun and the deflection system The electronic optical system formed is shown in Fig. 2. The application of the small and medium aperture (φ1.2 mm) diaphragm of the electron gun accelerating pole is one of the important assurances for obtaining a bright spot. The full length of the electron gun
