The Hardware and Software Design of Gamma-ray Directional Radiation Measuring Instrument

γ定向辐射探测仪的主要目的是用来测量一定方向上的γ射线。探测仪利用特别设计的探头及脉冲区分电路对探头接收的γ射线信号进行区分,分别计数,消除侧向信号对测量结果的影响,保证了测量的准确性。主要介绍了整个系统的工作原理以及硬件电路和软件设计。

Gamma- ray directional radiation measuring instrument is used to measure the gamma ray from the certain direction. Through designing specially detector and circuit （ Constant fraction discriminator）, the gam- ma rays from the forward and lateral direction were separated and counted independently. By eliminating the disturbance of the surrounding ray, the instrument ensures the accuracy of measurement. The paper mainly in- troduces the principle of the entire system and the composition of the hardware circuit and the software program- ming.
