Transferring Method of the Calibration Coefficient Between Secondary Neutron Calibrators

文章论述中子仪器刻度计算方法,以HH2530系列中子仪器为例,阐述在两种刻度器间刻度系数的传递方法,举例说明了用中子刻度水桶替代HH2530专用中子刻度器进行刻度的方法,并根据实例推导出新的标准比值,对中子刻度水桶刻度常规中子仪器的刻度结果进行了分析。刻度系数传递方法能够统一刻度计量器具和刻度标准,实现标准化作业。

The computing method for the calibration of neutron instrument is discussed in this paper. The author takes HH2530 series neu- tron instrument as an example to expound the transitive relation between two calibrators by using neutron instrument. By means of illustrating the calibration method by substituting the specialized neutron calibrator for HH2530 series with the neutron calibrated bucket, the author deduces new standard ratio in accordance with the example. After analyzing the calibration results calibrated on the conventional neutron instrument by neutron calibrated bucket, the author draws a conclusion that uniform calibrators and standards of calibrations, as well as standardized operations can be achieved by the transferring method of calibrations.
