Gated photomultiplier high-frequency sampling detection method

The invention relates to photomultiplier sampling, in particular to a high-frequency sampling detection method for a gated photomultiplier, and aims to solve the problems that in the prior art, the charge supplement speed of an electron dynode is far smaller than the electron output speed of electron multiplication, so that the amplitude of a subsequent detection signal is reduced or the subsequent detection signal cannot be output; a gated gating pulse with narrow pulse width and high repetition frequency is applied to a gated photomultiplier, and in the pulse width of the gated gating pulse, electrons emitted by a photoelectric cathode and electrons between the photoelectric cathode and an electron multiplier move to the electron multiplier for electron multiplication, so that the detection distortion phenomenon is avoided. And the anode outputs a corresponding detection pulse. 本发明涉及光电倍增管采样，具体涉及门控型光电倍增管高频采样探测方法，为解决现有技术中存在电子倍增极的电荷补充速度远小于电子倍增输出电子的速度，导致后续探测信号幅值下降或者无法输出，从而产生探测失真现象的不足之处，本发明对门控型光电倍增管施加窄脉冲宽度、高重复频率
