【摘要】 相对常规的电离室探测器,裂变电离室探测器以裂变核素作为主要的工作媒质,在与裂变核素相关的裂变物理实验研究以及中子测量等方面被广泛使用。本文简要介绍了本研究组近年来在平板状单层、多层裂变电离室以及筒状裂变电离室及其微型化、耐高温等特殊性能方面开展的设计和研制等研究工作,总结了利用自研的系列裂变电离室在锕系核素(铀、钚及其同位素)微观核参数、反应堆堆芯/堆外中子注量监测等方面取得的成果和应用情况。更多还原

【Abstract】 Compared with the conventional ionization chamber detectors, fission ionization chamber detectors use fission nuclides as the main working medium, and are widely used in fission physics experimental research related to fission nuclides and neutron measurement. The design and development of flat single-layer, multi-layer fission ionization chambers and cylindrical fission ionization chambers as well as their miniaturization, high temperature resistance and other special properties are introduced in this paper. It is also summarized the achievements and applications of our self-developed fission chambers in the measurements of microscopic nuclear parameters of actinide nuclides(uranium, plutonium and their isotopes), and in the neutron fluence monitoring of in-core/out-core reactors.更多还原
