摘要
本文主要通过探究盖革计数器的工作原理以及工作环境,对盖革计数器进行粒子辐射探测实验。利用高能射线粒子对惰性低压气体的电离性质,以及555定时器的脉冲整形,将高能射线粒子的存在形式转换为高频电脉冲信号,通过调理电路捕捉脉冲信号并闪烁led灯提示附近区域内存在高能射线粒子。
This paper mainly conducts particle radiation detection experiments on the Geiger counter by exploring the working principle of the Geiger counter and the working environment.Using the ionization properties of high-energy ray particles on the inert low-pressure gas,and the pulse shaping of the 555 timer,the existence form of the high-energy ray particles is converted into a high-frequency electric pulse signal,and the pulse signal is captured by the conditioning circuit and flashing the LED lamp to indicate the presence in the vicinity.High energy ray particles.
