标题： Moon Shadow Observation by IceCube

摘要： 在没有天体物理标准烛光的情况下，IceCube可以研究来自月球方向的宇宙射线缺失现象。 对此“月影”在下向μ子通量中的观测是对探测器相对于穿过的大能级μ子的绝对指向精度和角分辨率的实验验证。 已在IceCube的40根线配置中观测到了月影。 这是IceCube的第一个阶段，在此阶段月影分析取得了成功。 将讨论方法、结果以及一些系统误差研究。 显示英文摘要

摘要： In the absence of an astrophysical standard candle, IceCube can study the deficit of cosmic rays from the direction of the Moon. The observation of this "Moon shadow" in the downgoing muon flux is an experimental verification of the absolute pointing accuracy and the angular resolution of the detector with respect to energetic muons passing through. The Moon shadow has been observed in the 40-string configuration of IceCube. This is the first stage of IceCube in which a Moon shadow analysis has been successful. Method, results, and some systematic error studies will be discussed.
