本文综述北半球最大混合宇宙线探测器TA及其TALE、TAx4扩展的运行现状,并介绍能谱、各向异性和质量组成的最新结果。

摘要:

Telescope Array(TA)是北半球最大的混合型宇宙线探测器,观测能量范围从2 PeV到100 EeV的原初粒子。TA主探测器由507个塑料闪烁计数器组成,它们布置在间距1.2 km的方形网格上;三个站点还设有荧光探测器,俯瞰地面探测器阵列上方的天空。TA低能扩展(TALE)混合探测器由10台荧光望远镜以及80台间距400米和600米的加密地面探测器组成,自2018年建设完成以来持续提供稳定观测。将TA探测面积扩大至四倍的TAx4计划也在进行中。约半数计划中的探测器已经部署,目前的TAx4作为混合探测器继续稳定运行。我综述了TA实验的现状,以及宇宙线各向异性、质量组成和能谱方面的最新结果。

英文摘要:

The Telescope Array (TA) is the largest hybrid cosmic ray detector in the Northern Hemisphere, which observes primary particles in the energy range from 2 PeV to 100 EeV. The main TA detector consists of 507 plastic scintillation counters on a 1.2-km spacing square grid and fluorescence detectors at three stations overlooking the sky above the surface detector array. The TA Low energy Extension (TALE) hybrid detectors, which consists of ten fluorescence telescopes, and 80 infill surface detectors with 400-m and 600-m spacing, has continued to provide stable observations since its construction completion in 2018. The TAx4, a plan to quadruple the detection area of TA is also ongoing. About half of the planned detectors have been deployed, and the current TAx4 continues to operate stably as a hybrid detector. I review the present status of the TA experiment and the recent results on the cosmic-ray anisotropy, mass composition and energy spectrum.
