摘　　要：论文介绍了一种基于CPNB24涂硼计数管输出的小电流脉冲信号远距离传输快响应前置放大器的研制及性能测试结果。通过辐射探测器输出的小电流脉冲信号的远距离传输与放大,硼浓度得以快速准确地测量。为了后续计算堆芯硼浓度,该快速响应的前置放大器通过约100 m的低噪声同轴电缆与探测器连接。文中给出了该前放的基本原理图及测试方法及结果。This paper introduces the development and test performance results of a fast response preamplifier for long distance transmission, whose signals come from the small current pulse of the CPNB24 coated boron counter tube＇s output. By means of the long distance transmission and amplification of small current pulse signal of the nuclear detector, the boron＇s concentration can be measured quickly and accurately in nuclear power station. In order to calculate the concentration of boron, the fast response preamplifier is connected to the CPNB24 coated boron counter tube＇s by low - noise coaxial cable, which is about 100 meters long. This paper presents the basic schematic diagram of its fast response preamplifier, test - method and results.
