摘要
导出了球形计数器中子探测效率与其结构参数的关系。计算和测量了~3He球形正比计数器对一已知温度麦克斯韦谱中子的探测效率,计算值与实验值在实验误差以内相符。
The relations between the neutron detection efficiency of the sphericalcounter and its structural parameter are deduced. The detection efficiencies ofthe ~3He spherical proportional counters for the Maxwell neutrons spectrum, whosetemperature is known, are calculated and measured. The calculated values areconsistent with the measured values in the experimental error.
