| Research Abstract |
In order to reveal the origin of the extremely high energy cosmic rays (EHECRs) with the energies above 1020 eV, it is effective to detect extremely high energy neutrinos derived from those EHECRs. I developed a method to increase the sensitivity of a large Cherenkov photon detector for those neutrinos. Events between background atmospheric muon bundles and single muons derived from those neutrinos apparently look similar, however, I found that there is a difference of the Cherenkov photon distribution in the moving direction. More neutrino signals can be obtained by using the difference.
