本文描述一个快随机脉冲发生装置的结构和性能。它由快光源、快光电倍增管、快甄别、快放大、快计数和负反馈稳定回路构成。时不变快随机脉冲平均计数率可接近10
8
cps。时变随机脉冲可随任意时变函数变化。
This paper describes the construction and specifications of a fast random pulse generator. It consists of
a
fast LED light source
a PMT
a fast discriminator
a fast amplifier
a fast counter and a negative feedback stable circuit. The counting rate of time non-variant random pulses is near 10
3
cps. Time variant random pulses can vary with the shape of time variant pulse.
