Cosmic Ray Observation at Antarctic Zhongshan Station
-
摘要: 2014年由两个具有0.5m×0.5m闪烁体面积的探测器组成的宇宙线μ子望远镜在南极中山站建成,观测数据通过卫星链路传回并发布.通过对中山站μ子望远镜数据的气象效应分析,发现中山站的气压变化对宇宙线计数率影响显著并呈负相关.计算得到宇宙线高能质子在中山站的垂直截止刚度RC为0.076GV,对比中国西藏羊八井和北京高能质子的垂直截止刚度,中山站非常有利于对太阳高能质子事件的观测.Abstract: By the end of 2014, a cosmic ray muon telescope consisting of two detectors which has 0.5m×0.5m area scintillator was installed at Antarctic Zhongshan Station. The observation data is sent to China by satellite link and is released through network, which can be used to monitor and forecast space environment disasters, and provides support for China operational monitoring of space environment and multidisciplinary research of Polar Regions. The Zhongshan Station muon telescope data shows that there is a significant effect of pressure change with negative correlations. The vertical cutoff rigidity of cosmic ray protons at Zhongshan Station is 0.076GV, compared with those observations from Yangbajing and Beijing in China, Zhongshan Station is very conducive to the observation of the solar proton events.
