Eric Albin, Daniel Whiteson

AI总结:

本研究探究全球宇宙射线探测器网络对远距离同时性广延空气簇射的探测灵敏度,验证CRAYFIS实验在两种用户规模下的探测能力,为超高能宇宙线相关新现象观测提供新途径。

摘要:

我们探究了全球宇宙射线探测器网络对一种尚未被观测到的新现象——空间相隔甚远的同时性广延空气簇射——的探测灵敏度。现有的局地观测站均独立工作以观测单个簇射,为揭示超高能宇宙射线的来源与性质提供认知。但当前没有任何观测站的规模足以对预期过程(如GZ效应或可能产生相隔数百至数千公里的同时性空气簇射的新物理现象)具备探测灵敏度。由消费电子设备组成的全球网络(CRAYFIS实验)或许为观测这类现象提供了全新机遇。我们探究了两种用户场景:第一种为用户参与度最大化的场景,研究发现数年内即可在空间分离但时间重合的簇射探测方面取得具有统计显著性的发现;第二种为更符合实际的参与模型,即拥有10^6台活跃设备,研究发现全球范围的CRAYFIS能够对大量同时发生EAS的新型“爆发”现象具备探测灵敏度。

英文摘要:

We explore the sensitivity offered by a global network of cosmic ray detectors to a novel, unobserved phenomena: widely separated simultaneous extended air showers. Existing localized observatories work independently to observe individual showers, offering insight into the source and nature of ultra-high energy cosmic rays. However no current observatory is large enough to provide sensitivity to anticipated processes such as the GZ effect or potential new physics that generate simultaneous air showers separated by hundreds to thousands of kilometers. A global network of consumer electronics (the CRAYFIS experiment), may provide a novel opportunity for observation of such phenomena. Two user scenarios are explored. In the first, with maximal user adoption, we find that statistically significant discoveries of spatially-separated but coincident showers are possible within a couple years. In the second, more practical adoption model with $10^6$ active devices, we find a worldwide CRAYFIS to be sensitive to novel "burst" phenomena where many simultaneous EASs occur at once.
