低、负中子增殖系数测量中统计涨落的计算机模拟

Computer simulation of statistical fluctuation in the measurement of low and negative neutron breeding coefficients

采用构造理想函数加上各种类型涨落偏差,利用数值模拟的方法,模拟了统计涨落对零功率堆中子增殖系数(俗称α参数)测量结果的影响。另外,还对闪烁体和记录系统等也采用了数值模拟的方法来估算统计涨落对测量结果的影响。

Through producing ideal function and setting up various kinds of fluctuation errors, we numerally simulate effects of statistical fluctuation on the measurement of low and negative neutron breeding coefficients, and we also simulate effects of scintillator, cable and recording system.
