【摘要】 本文描述了用于0.1—18MeV单能快中子注量率绝对量的闪烁望远镜,半导体望远镜,含氢正比计数器和伴随粒子法等绝对测量装置。并刻度了用作这一能区次级标准的长中子计数器的效率,用这套装置参加了最近由国际计量局组织的中子注量率测量的国际比对,并给出了比对结果。更多还原

【Abstract】 The methods for absolute measurement of 0.1-18 MeV monoenergetic neutron fluence rate are described, which include proton recoil telescope, semiconductor telescope, hydrogen filled proportional counter and associated partical method. A long counter used as secondary standard was calibrated by using these methods. We participated in recent international intercomparison of neutron fluence rete organized by BIPM, and the results were given.更多还原
