EUSO-TA检测器的结果和状态

Results and status of the EUSO-TA detector

Lech Wiktor Piotrowski

摘要:

EUSO-TA是一个地基望远镜,位于美国犹他州望远镜阵列(TA)的Black Rock Mesa站点。该仪器的主要目的是通过探测宇宙射线簇射产生的紫外线来观测超高能宇宙射线。EUSO-TA由两个1 m2的菲涅尔透镜组成,视场约为11 x11度。光聚焦在由36个滨松多阳极光电倍增管组成的光电探测器模块上,总共有2304个通道。在操作过程中,望远镜被放置在TA荧光检测器前面的一个棚子里。我们介绍了2015年和2016年EUSO-TA观测活动的结果,包括探测到的宇宙射线、流星和激光发射。还显示了当前仪器设置和探测器升级到第二阶段的详细情况。

英文摘要:

EUSO-TA is a ground-based telescope, located at the Black Rock Mesa site of Telescope Array (TA), Utah, USA. The main aim of the instrument is observation of Ultra High Energy Cosmic Rays through detection of ultraviolet light generated by cosmic-ray showers. EUSO-TA consists of two, 1 m2 Fresnel lenses with a field of view of about 11x11 deg. Light is focused on the Photo Detector Module composed of 36 Hamamatsu multi-anode photomultipliers, for a total of 2304 channels. During operations, the telescope is housed in a shed located in front of the TA Fluorescence Detector. We present the results from EUSO-TA observational campaigns performed in years 2015 and 2016, including detected cosmic rays, meteors and laser shots. Also shown are the details of current instrument setup and upgrade of the detector to phase II.
