提出了一种基于贝克-纳恩光学的超高能宇宙线观测望远镜的设计方案。光学系统在50°角直径的宽视场内具有优于0.02°的图像分辨率。当与高质量的成像设备相结合时，所提出的设计能够以优于1弧分的精度确定UHECR和高能中微子的方向。这台望远镜杰出的分辨率使电荷分离的宇宙射线得以分辨，并精确地确定其来源。角分辨率的这一显著提高将使人们能够通过与现有天文观测的合作，对天文物体进行多波长和“多粒子”观测。
A new telescope design based on Baker–Nunn optics is proposed for observation of ultra-high-energy cosmic rays (UHECRs). The optical system has an image resolution better than 0.02° within a wide field of view of 50° angular diameter. When combined with a high-quality imaging device, the proposed design enables the directions of UHECRs and high-energy neutrinos to be determined with an accuracy better than 1 arcmin . The outstanding resolution of this telescope allows charge-separated cosmic-rays to be resolved and the source to be determined accurately. This marked improvement in angular resolution will allow the multi-wavelength and “multi-particle” observations of astronomical objects through collaboration with established astronomical observations.
