光电倍增管的高压电源变化1%,则其放大系数将改变10%以上.因此,要正确使用光电倍增管,必须首先认真研制光电倍增管高压电源.Gonda等人提出了一种新型的光电倍增管高压电源线路,上海植生所据此进行了制作,在植生所制作的基础上我们对它作了一些修改,线路如图1所示,其工作原理如下:经倍压整流而得未稳压的高压,经过两个控制晶体管DF104B和电流检测器后,接在输出端.输出 PMT tube high-voltage power supply change of 1%, then the amplification factor will change more than 10% .To correct use of photomultiplier tube, we must first carefully develop PMT high-voltage power supply.Gonda et al proposed a new type of photomultiplier Based on this, we made some modifications to the high voltage power supply line and the Shanghai Plantation Institute. Based on the production made by the Plantation Institute, we made some modifications to it. The circuit is shown in Figure 1. The working principle is as follows: Unbalanced Of the high voltage, after two control transistor DF104B and current detector, then connected to the output. Output
