EUSO-TA是一台地面望远镜，安装在美国犹他州黑岩梅萨的望远镜阵列（TA）站点。这是第一个成功使用基于菲涅耳透镜的光学系统和多阳极光电倍增管（每管64个通道，2304个通道，涵盖10.6度x 10.6度的视场）来探测超高能量宇宙射线（UHECR）的探测器。该望远镜位于TA实验的荧光探测器之一的前面。自2013年安装以来，该探测器已观测到几次超高能宇宙射线事件，此外还有流星。已确定总和帧的极限幅度为5.5（类似于3 ms）。完成了不同条件、月相和位置下夜空紫外辐射的测量。所进行的观察作为这种探测器技术未来应用的概念证明。(C)2018爱思唯尔B. V.保留所有权利。
EUSO-TA is a ground-based telescope, installed at the Telescope Array (TA) site in Black Rock Mesa, Utah, USA. This is the first detector to successfully use a Fresnel lens based optical system and multi-anode photomultipliers (64 channels per tube, 2304 channels encompassing a 10.6 degrees x 10.6 degrees field of view) for detection of Ultra High Energy Cosmic Rays (UHECR). The telescope is located in front of one of the fluorescence detectors of the TA experiment. Since its installation in 2013, the detector has observed several ultra-high energy cosmic ray events and, in addition, meteors. The limiting magnitude of 5.5 on summed frames (similar to 3 ms) has been established. Measurements of the UV night sky emission in different conditions and moon phases and positions have been completed. The performed observations serve as a proof of concept for the future application of this detector technology. (C) 2018 Elsevier B.V. All rights reserved.
