随着激光的发展,尤其是第二、第三代激光卫星测距的出现,对高压快速脉冲要求愈来愈高。不但上升前沿要快,抖动亦要小。为了得到这类脉冲,首先要解决快速开关元件。由于国内尚无KN_(22)之类器件,本试验对三电极触发管进行了测试,力图将此管用于要求更高的场合,以满足某些试验的要求。触发管的简单原理触发管G是一种冷阴极三极可控开关管,其结构如图1。a是主电极(阳极),b为中心
With the development of the laser, especially the emergence of the second and third generation laser satellite ranging, the requirements for high-voltage fast pulse are getting higher and higher. Not only the rising front faster, jitter also smaller. In order to get such a pulse, we must first solve the fast switching element. Due to the absence of KN_ (22) and other devices in our country, we tested the three-electrode trigger tube and tried to use the tube in more demanding situations to meet the requirements of some experiments. Simple trigger trigger tube Trigger tube G is a cold cathode triode controllable switch, the structure shown in Figure 1. a is the main electrode (anode), b is the center
