摘要:

我们提出了一个概念,大面积,低成本的超高能宇宙射线(UHECR)的单像素望远镜(FAST)的荧光探测器阵列的检测,解决下一代的UHECR实验的要求。在FAST设计中,大视场由反射镜或菲涅耳透镜的焦平面处的几个像素覆盖。我们报告的第一个结果的FAST原型安装在望远镜阵列网站,包括一个单一的200毫米光电倍增管在焦平面的1米$^2$菲涅尔透镜系统采取的原型的JEM-EUSO实验。FAST原型在19个夜晚进行了数据采集,显示出卓越的运行稳定性。我们在几公里的距离上探测到了激光发射,以及16个非常重要的UHECR阵雨候选者。

英文摘要:

We present a concept for large-area, low-cost detection of ultra-high energy cosmic rays (UHECRs) with a Fluorescence detector Array of Single-pixel Telescopes (FAST), addressing the requirements for the next generation of UHECR experiments. In the FAST design, a large field of view is covered by a few pixels at the focal plane of a mirror or Fresnel lens. We report first results of a FAST prototype installed at the Telescope Array site, consisting of a single 200 mm photomultiplier tube at the focal plane of a 1 m$^2$ Fresnel lens system taken from the prototype of the JEM-EUSO experiment. The FAST prototype took data for 19 nights, demonstrating remarkable operational stability. We detected laser shots at distances of several kilometres as well as 16 highly significant UHECR shower candidates.
