Design of UHECR telescope with 1 arcmin resolution and 50 degree field   of view
  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 of smaller than 0.02$^\circ$ within a wide field of view of 50$^\circ$ 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 accuracy of 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.
