对高能外星中微子的观测是未来最有希望的选择之一，可以增加我们对宇宙中非热过程的了解。例如，中微子不可避免地在高能强子碰撞的环境中产生；特别是，在宇宙射线的天体物理加速器中，这几乎肯定是正确的，因此可以通过“中微子光”的天空观测明确地识别出来。为了建立超越单一事件探测的中微子天文学，需要千米尺度的中微子望远镜。为了获得全天空覆盖，需要在地中海安装相应的探测器，以补充目前正在南极建造的冰立方实验。目前在地中海进行中微子望远镜项目的小组，ANTARES， NEMO和NESTOR，已经加入准备这个未来的装置，在一个为期3年的欧盟资助的设计研究中，名为KM3NeT（在下面，这个名字也将表示未来的探测器）。本报告将重点介绍KM3NeT需要解决的一些物理问题，并将概述其实现的路径，重点是即将进行的设计研究。
The observation of high-energy extraterrestrial neutrinos is one of the most promising future options to increase our knowledge on non-thermal processes in the universe. Neutrinos are e.g. unavoidably produced in environments where high-energy hadrons collide; in particular, this almost certainly must be true in the astrophysical accelerators of cosmic rays, which thus could be identified unambiguously by sky observations in “neutrino light”. To establish neutrino astronomy beyond the detection of single events, neutrino telescopes of km3scale are needed. In order to obtain full sky coverage, a corresponding detector in the Mediterranean Sea is required to complement the IceCube experiment currently under construction at the South Pole. The groups pursuing the current neutrino telescope projects in the Mediterranean Sea, ANTARES, NEMO and NESTOR, have joined to prepare this future installation in a 3-year, EU-funded design study named KM3NeT (in the following, this name will also denote the future detector). This report will highlight some of the physics issues to be addressed with KM3NeT and will outline the path towards its realisation, with a focus on the upcoming design study.
