摘要
重点研究了圆柱形正比计数器对不同能量γ射线的响应情况,利用蒙特卡罗方法计算了各能量γ射线在计数器中的沉积能量值,鉴于气体中原子电离的统计涨落特性,在沉积能量的基础之上利用统计学方法简单计算了原子电离所产生的离子对数,并将其近似为计数器的能量响应情况。提供了一种正比计数器能量响应的分析方法,并利用这种方法分析了正比计数器的能量响应特性。
The energy response of cylindrical proportional counter to gamma radiation of various energies is stud- ied in this article, and its energy deposited in counter is computed with Monte Carlo simulation. Because of sta- tistical character of ionization in gas, statistical methods are employed for the number of ions produced in atom ionization, which is accepted approximately as energy response of proportional counter. One energy response a- nalysis method of proportional counter is presented in this article, and energy response character of proportional counter is analyzed by this way.
