Neutron fluence measurement - part 6 : fast - neutron fluence determination with thorium fission detectors
中子注量測量.第6部分:用釷裂變探測器測定快中子注量The error source in measuring neutron fluence rate is gived. the efficiency of u - fission chamber is studied. the effect factors to detector are analyzed and experimentally studied
開展了鈾裂變室探測器效率的研究，對影響探測器對期望中子或非期望中子探測的各種因素進行了分析和實驗研究。The experiment was carried out at the lawrence berkeley national laboratory ( u. s. a ). a 252cf was placed at the center of the gammasphere detector array which, for this experiment, consisted of 102 compton - suppressed ge detectors. by measuring prompt - ray of spontaneous fission from 252cf, a total of 5. 7 1011 triple - and higher - fold coincidence events were collected
實驗工作是在美國洛侖茲伯克利國家實驗室（ lbnl ）的gammasphere探測裝置上完成的， 252cf自發裂變源放置在一個由102個反康ge探測器組成的gammasphere探測器陣列的中心，測量自發裂變產生的瞬發譜，記錄三重以上的符合事件。The effect of detector disturb and the shell of the detector and construction material is not distinct. the low absorb cross section material is used to 235u - fission chamber. the low z material is used in experimental bracket and shielding material and the material is used less
獲得了探測器之間擾動、探測器外殼、支架材料對信號中子測量無明顯影響的結果；對~ （ 235 ） u裂變電離室，需採用中子吸收截面低的材料，對實驗裝置的支撐材料和屏蔽材料宜選用低z材料且盡量減少用材。分享友人
