OPERA中微子实验的现状

Status of the OPERA neutrino experiment

H. Pessard

摘要:

OPERA长基线振荡实验位于意大利Gran Sasso地下实验室。OPERA的设计目的是观察CNGS nu-mu束中的nu-mu -> nu-tau现象,距离CERN的源730公里。该仪器由一套大型乳胶铅靶和电子探测器组成。2007年和2008年的首次运行帮助检查了探测器和相关乳胶设施是否充分运作,并成功地对收集到的数据进行了首次分析。在对OPERA设置进行简短描述后,该演讲将介绍用于中微子事件样本的数据重建和分析的最新状态报告。

英文摘要:

The OPERA long-baseline oscillation experiment is located in the underground Gran Sasso laboratory in Italy. OPERA has been designed to observe nu-mu -> nu-tau appearance in the CNGS nu-mu beam, 730 km away from its source at CERN. The apparatus consists of a large set of emulsion-lead targets combined with electronic detectors. First runs in 2007 and 2008 helped checking that detector and related emulsion facilities are fully operational and led to successful first analysis of collected data. The talk, after a short description of the OPERA setup, will present an updated status report on data reconstruction and analysis applied to present samples of neutrino events.
