摘要:

本文介绍了萨德伯里中微子天文台(SNO)24 Na和222 Rn分布式源的产生和分析。这些独特的来源提供了对中子的响应的精确校准,中子是通过重水靶中的氘的光致衰变产生的,以及对低能β和γ的响应。介绍了这些光源在测定~ 3 He正比计数器阵列中子探测效率和响应以及痕量天然放射性背景切伦科夫光特性中的应用。

英文摘要:

The production and analysis of distributed sources of 24Na and 222Rn in the Sudbury Neutrino Observatory (SNO) are described. These unique sources provided accurate calibrations of the response to neutrons, produced through photodisintegration of the deuterons in the heavy water target, and to low energy betas and gammas. The application of these sources in determining the neutron detection efficiency and response of the 3He proportional counter array, and the characteristics of background Cherenkov light from trace amounts of natural radioactivity is described.
