OPERA实验乳胶/铅靶中中微子相互作用的探测

The detection of neutrino interactions in the emulsion/lead target of the OPERA experiment

N. Agafonova

摘要:

位于格兰萨索地下实验室(LNGS)的OPERA中微子探测器旨在通过研究$ν_μ\toν_τ$振荡,首次以外观模式探测中微子振荡。该装置由一个由电子探测器补充的乳胶/铅靶组成,它被放置在距离中微子源730公里的高能长基线CERN到LNGS束(CNGS)中。2007年和2008年成功地进行了CNGS中微子探测,探测器及其相关设施完全运行,用于乳胶处理和分析。在简单描述了束流和实验装置后,我们报告了中微子相互作用事件的第一个样本的收集、重建和分析过程。

英文摘要:

The OPERA neutrino detector in the underground Gran Sasso Laboratory (LNGS) was designed to perform the first detection of neutrino oscillations in appearance mode through the study of $ν_μ\toν_τ$ oscillations. The apparatus consists of an emulsion/lead target complemented by electronic detectors and it is placed in the high energy long-baseline CERN to LNGS beam (CNGS) 730 km away from the neutrino source. Runs with CNGS neutrinos were successfully carried out in 2007 and 2008 with the detector fully operational with its related facilities for the emulsion handling and analysis. After a brief description of the beam and of the experimental setup we report on the collection, reconstruction and analysis procedures of first samples of neutrino interaction events.
