South Pole Air Shower Experiment for Gamma Ray Astronomy at Ultra-High Energy

该项目是南极气淋实验（SPASE）的延续，SPASE是1988年安装的一个大型相控阵闪烁探测器，用于搜索南方天空中超高能量（100 GeV）伽马射线的天体物理源。自安装以来，SPASE每年都在升级，但到目前为止，还没有找到令人信服的证据证明它存在强大的辐射源，这与其他地方类似的探测器的结果一致。这项为期一年的拨款将允许SPASE与刚刚安装在南极的新μ子探测器一起运行。该项目是特拉华大学Bartol研究所和英国利兹大学的合作项目。

This project is the continuation of the South Pole Air Shower Experiment (SPASE), a large phased array of scintillation detectors which was installed in 1988 to search the southern sky for astrophysical sources of ultra-high energy (100 GeV) gamma rays. SPASE has been upgraded every year since its installation, but to date has not found convincing evidence for a strong source, a result that is consistent with similar detectors elsewhere. This one year grant will allow SPASE to operate in conjunction with a new muon detector which has just been installed at South Pole. This project is a collaboration between Bartol Research Institute of the University of Delaware and Leeds University in the United Kingdom.
