冰立方中微子探测器是一个立方公里的TeV到PeV中微子探测器，正在地理南极建造。在冰立方中探测到的主要中微子群是由于宇宙射线空气阵雨中的介子衰变。这些大气中微子相对来说已经被很好地理解了，可以作为新探测器的校准和验证工具。2006年，探测器大约完成了10%，我们报告了在这种配置下从探测器获得的数据。我们观察到与预期一致的大气中微子信号，证明冰立方探测器能够识别中微子事件。在最初的137.4天的生存时间里，选择了234个候选中微子，期望从大气中微子中获得211 +/- 76.1(syst)+/- 14.5（stat）事件。
The IceCube neutrino detector is a cubic kilometer TeV to PeV neutrino detector under construction at the geographic South Pole. The dominant population of neutrinos detected in IceCube is due to meson decay in cosmic-ray air showers. These atmospheric neutrinos are relatively well understood and serve as a calibration and verification tool for the new detector. In 2006, the detector was approximately 10% completed, and we report on data acquired from the detector in this configuration. We observe an atmospheric neutrino signal consistent with expectations, demonstrating that the IceCube detector is capable of identifying neutrino events. In the first 137.4 days of live time, 234 neutrino candidates were selected with an expectation of 211 +/- 76.1(syst)+/- 14.5(stat) events from atmospheric neutrinos.
