AMANDA 7 Year Data

The Antarctic Muon And Neutrino Detector Array (AMANDA) is an optical Cherenkov detector consisting of 677 optical modules arranged in 19 strings frozen ~1.5 km -- ~2 km deep in the ice sheet at the geographic South Pole. Each optical module contains a 20 cm photomultiplier tube surrounded by a glass pressure sphere housing. Cherenkov light emitted by energetic particles inside the AMANDA volume is detected by the modules, and resulting PMT pulses are propagated to the surface and processed by trigger logic. AMANDA-II has operated from 2000 -- 2006 and has recorded 6595 upgoing events in 3.8 years of livetime during this period.

南极μ子与中微子探测器阵列（AMANDA）是一款光学切伦科夫探测器（optical Cherenkov detector），由19串共计677个光学模块组成，这些模块被封装于地理南极处冰盖下方约1.5千米至2千米的冰层之中。每个光学模块均搭载一枚20厘米口径的光电倍增管（photomultiplier tube，PMT），该光电倍增管被封装在玻璃耐压球壳内。AMANDA探测体积内的高能粒子所辐射出的切伦科夫光会被这些光学模块捕获，由此产生的光电倍增管脉冲信号会被传输至地面，并通过触发逻辑进行处理。AMANDA-II于2000年至2006年间运行，在此期间的3.8年有效运行时长内，共记录到6595次上行事件。
