IceCube:建设现状和初步成果

IceCube: Construction Status and First Results

Albrecht Karle

摘要:

IceCube是目前正在南极建造的一个1立方公里的中微子望远镜。该探测器将由4800个光学传感器组成,部署在1450米至2450米的深度,均匀分布在80个字符串中。在冰内探测器上方1平方公里范围内的空气簇射阵列将测量能量范围从300 TeV到1 EeV以上的宇宙射线空气簇射。该探测器被设计用来探测所有类型的中微子。目前有40个字符串正在运行,建设完成了50%。根据迄今为止获得的数据,天文台达到了设计目标,目前超过了AMANDA和以前中微子望远镜的灵敏度。还讨论了建设前景和未来可能的扩展。

英文摘要:

IceCube is a 1 km3 neutrino telescope currently under construction at the South Pole. The detector will consist of 4800 optical sensors deployed at depths between 1450 m and 2450 m in clear Antarctic ice evenly distributed over 80 strings. An air shower array covering a surface area of 1 km^2 above the in-ice detector will measure cosmic ray air showers in the energy range from 300 TeV to above 1 EeV. The detector is designed to detect neutrinos of all flavors. With 40 strings currently in operation, construction is 50% complete. Based on data taken to date, the observatory meets its design goals and currently exceeds the sensitivity of AMANDA and previous neutrino telescopes. The construction outlook and possible future extensions are also discussed.
