气体正比管一维位置灵敏特性研究
|
摘要
通过电荷分配法原理,运用软件ROOT进行数据处理,研究一维位置灵敏正比管气体探测器位置分布的线性和分辨。结果表明,一维正比管探测器在工作电压为1 700 V和1 800 V时,位置分布的线性良好,分辨均小于10 mm。
The linearity of position distribution and the position resolution of the gas proportional counters are researched by charge dividing mechanism. The experimental data is processed by ROOT software. The results show that the one-dimensional proportional counters has an excellent linearity of position distribution,and the position resolution is less than 10 mm,when the operating voltage is 1 700 V and 1 800 V.
