Scale Method of Conversion Coefficient for Capturing Detector

摘要: 本文介绍了一种用于裂变率测量的俘获探测器，研究了俘获探测器转换系数刻度方法。结果表明，特征γ射线刻度方法不受冷却时间的影响，有利于保证转换系数的适用性。在贫化铀装置内两个不同位置用裂变室对两个俘获探测器进行了刻度，两个俘获探测器的转换系数在4%的误差范围内一致。

Abstract: In this paper, a capturing detector used to measure fission rates was introduced, and the scale method of conversion coefficient of capturing detector was studied. The results indicate that the character γ-rays scale method isn’t affected by cooling time, and this is advantageous to ensure the applicability of the conversion coefficient. Two capturing detectors were scaled by fission chamber in depleted uranium set, and the conversion coefficients of two capturing detectors are coincident in 4% error range.
