2011年3月7日和9月25日地面中子望远镜SEDA-FIB和FERMI-LAT探测到的太阳γ射线和太阳中子的分析
Analysis of solar gamma rays and solar neutrons detected on March 7th and September 25th of 2011 by Ground Level Neutron Telescopes, SEDA-FIB and FERMI-LAT
摘要：
在红十字国际委员会第33届会议上，我们报告了地面探测器可能探测到太阳伽马射线的情况，后来又重新研究了这一事件。2011年3月7日，位于北京市朝阳区的太阳中子望远镜（SNT），墨西哥Sierra Negra（海拔4，600米）观测到从19：49到20：02 UT和从20：50到21：01 UT的计数率增强。统计学显著性分别为9.7西格玛和8.5西格玛。本文讨论了利用这种高山探测器探测太阳γ射线的可能性。与此事件相关，国际空间站上的太阳中子探测器SEDA-FIB也探测到了7.5西格玛的太阳中子。FERMI-LAT探测器也观测到来自这个耀斑的高能伽马射线，统计显著性为6.7西格玛。因此，我们试图建立一个统一的模型来解释这些数据。本文报道了2011年9月25日位于西藏（海拔4,300米）的SNT在04：37 - 04：47 UT期间探测到的另一个太阳γ射线候选者，其统计显著性为8.0 sigma（采用Li-Ma方法）。
英文摘要：
At the 33rd ICRC, we reported the possible detection of solar gamma rays by a ground level detector and later re-examined this event. On March 7, 2011, the solar neutron telescope (SNT) located at Mt. Sierra Negra, Mexico (4,600 m) observed enhancements of the counting rate from 19:49 to 20:02 UT and from 20:50 to 21:01 UT. The statistical significance was 9.7sigma and 8.5sigma, respectively. This paper discusses the possibility of using this mountain detector to detect solar gamma rays. In association with this event, the solar neutron detector SEDA-FIB onboard the International Space Station has also detected solar neutrons with a statistical significance of 7.5sigma. The FERMI-LAT detector also observed high-energy gamma rays from this flare with a statistical significance of 6.7sigma. We thus attempted to make a unified model to explain this data. In this paper, we report on another candidate for solar gamma rays detected on September 25th, 2011 by the SNT located in Tibet (4,300 m) from 04:37 to 04:47 UT with a statistical significance of 8.0sigma (by the Li-Ma method).
