欧洲地下站点中微子束的优化

Optimization of neutrino beams for underground sites in Europe

A. Longhin

摘要:

我们提出了一个优化程序的中微子束,可以产生在欧洲核子研究中心,并针对一组7个可能的地下站点在欧洲的距离从130公里到2300公里。在LAGUNA设计研究第一阶段的范围内,对这些地点进行了关于下一代超大质量中微子观测站的可行性研究。我们考虑质子驱动程序(高功率质子驱动程序在4.5 GeV的最短基线和50 GeV的机器较长的基线)和远探测器(水切伦科夫最短的基线和LAr TPC较长的基线)的具体情况。通量模拟受益于完整的GEANT4模拟。在最近的反应堆和加速器实验的nu_e出现的结果之前已经进行了优化,因此它是基于θ 13的灵敏度的最大化。尽管如此,优化的通量自其在互联网上发表以来(2010年)已被广泛使用。因此,这项工作的主要目的是作为一个文件所采用的方法,并在同一时间作为一个中间步骤,对未来的研究,这将把重点放在梁的性能研究的delta_CP。

英文摘要:

We present an optimization procedure for neutrino beams which could be produced at CERN and aimed to a set of seven possible underground sites in Europe with distances ranging from 130 km to 2300 km. Studies on the feasibility of a next generation very massive neutrino observatory have been performed for these sites in the context of the first phase of the LAGUNA design study. We consider specific scenarios for the proton driver (a high power proton driver at 4.5 GeV for the shortest baseline and a 50 GeV machine for longer baselines) and the far detector (a Water Cherenkov for the shortest baseline and a LAr TPC for longer baselines). The flux simulation profits of a full GEANT4 simulation. The optimization has been performed before the recent results on nu_e appearance by reactor and accelerator experiments and hence it is based on the maximization of the sensitivity on theta13. Nevertheless the optimized fluxes have been widely used since their publication on the internet (2010). This work is therefore mainly intended as a documentation of the adopted method and at the same time as an intermediate step towards future studies which will put the emphasis on the performances of beams for the study of delta_CP.
