摘要:

INFN和ICARUS合作最初开发了LAr-TPC技术。ICARUS T600探测器位于地下LNGS Hall-B,已经运行了三年多,具有出色的探测效率,运行平稳,寿命长,可靠性高。大约有3000个CNGS中微子事件已经收集并正在积极分析中。ICARUS现在将被转移到CERN进行广泛的研发计划。T600探测器将进行大修,并补充类似的T150探测器。这些改进是与黎巴嫩国家教育局的实验合作进行的,现在有几个INFN机构是该实验的成员。作为一种新颖性,将引入约1 T的SC磁场。在2016年期间,建议将实验转移到FNAL,在那里可以获得短基线中微子束,补充已批准的MicroBooNe实验,该实验将于2014年开始运行。FNAL的ICARUS探测器将是一个重要的补充,因为在没有异常的情况下,距离目标不同距离的几个探测器的信号对于所有实验特征来说应该是彼此的复制。由于质量减少,MicroBooNE中的反中微子信号太弱,无法进行灵敏的比较。因此,LSND异常的明确澄清需要探索由更大的T600提供的反中微子信号。磁场将允许从中微子诱导的背景中分离反中微子信号。建议在距目标约700 m的助推器NuBeam处对T600进行曝光; T150将位于约150 m处。T600还将从离轴NUMI束接收>10^4 nu_e事件/年,峰值约为1 GeV,可用于为LBNE实验做准备。ICARUS小组也有兴趣将参与范围扩大到与现有FNAL小组合作的其他短基线中微子活动。

英文摘要:

The INFN and the ICARUS collaboration originally developed the technology of the LAr-TPC. Located the underground LNGS Hall-B, the ICARUS T600 detector has been performed over three years with remarkable detection efficiency featuring a smooth operation, high live time, and high reliability. About 3000 CNGS neutrino events have been collected and are being actively analyzed. ICARUS will now be moved to CERN for an extensive R&D program. The T600 detector will be overhauled and complemented with a similar T150 detector. These improvements are performed in collaboration with the LBNE experiment, of which several INFN Institutions are now members. As a novelty, a SC magnetic field of about 1 T will be introduced. During 2016 it is proposed to move the experiment to FNAL where short base line neutrino beams are available, complementing the approved MicroBooNe experiment which will start operation in 2014. The ICARUS detectors at FNAL will be an important addition since, in absence of anomalies, the signals of several detectors at different distances from the target should be a copy of each other for all experimental signatures. Due to the reduced mass, in MicroBooNE the anti-neutrino signal is too weak for a sensitive comparison. Hence, a definitive clarification of the LSND anomaly requires the exploration of the anti-neutrino signal provided by the much larger T600. The magnetic field will allow separating the anti-neutrino signal from the neutrino-induced background. It is proposed to expose the T600 at the Booster NuBeam at ~700 m from target; the T150 will be located at ~150 m. The T600 will also receive >10^4 nu_e events/year from the off-axis NUMI beam peaked around 1 GeV and exploitable to prepare for the LBNE experiment. The ICARUS teams are also interested in extending the participation to other short baseline neutrino activities collaborating with existing FNAL groups.
