光电倍增管的增益，是阳极输出电流和光电阴极中光电流的比值，直接关系到电源电压。
The gain of the PMT, that is the ratio of anode output current to the photoelectric current from the photocathode, is directly related to the supply voltage.
为了得到所需要的64输出线以连接led的阳极，我们将创建一个简单的多路电路。
To get get the required 64 output lines needed for the LED anodes, we will create a simple multiplexer circuit.
这些光电子通过倍增器电极时由于次级电子发射而倍增，然后被阳极收集成为一个输出脉冲。
These photoelectrons are multiplied by secondary electron emission through the dynodes and then collected by the anode as an output pulse.
