日本的T2 K长基线中微子振荡实验需要精确预测初始中微子通量。最高的精度可以达到基于强子发射的详细测量从相同的目标所使用的T2 K暴露于相同的动能为30 GeV的质子束。2007年至2010年，欧洲核子研究中心SPS的NA 61/SHINE实验使用T2 K石墨靶的复制品记录了相应的数据。本文详细介绍了2007年试验的实验、数据采集、数据分析方法和结果。此外，还介绍和讨论了NA 61/SHINE测量在T2 K初始中微子流预测中的应用。
The T2K long-baseline neutrino oscillation experiment in Japan needs precise predictions of the initial neutrino flux. The highest precision can be reached based on detailed measurements of hadron emission from the same target as used by T2K exposed to a proton beam of the same kinetic energy of 30GeV. The corresponding data were recorded in 2007–2010 by the NA61/SHINE experiment at the CERN SPS using a replica of the T2K graphite target. In this paper details of the experiment, data taking, data analysis method and results from the 2007 pilot run are presented. Furthermore, the application of the NA61/SHINE measurements to the predictions of the T2K initial neutrino flux is described and discussed.
