Abstract
In astrophysics, neutrinos provide important information from cosmos due to its interaction among matters along its passage in the universe can hardly occur. We can know more about the origins of UHECR and the early cosmos evolution via neutrino detectors.
NuTel is a telescope designed to observe the Cherenkov light from air showers aroused by τ neutrinos. We are interested in the energy range between 1015~1018ev since this energy range is not covered by the conventional neutrino detectors or UHECR detectors. The size of NuTel is about 2 meter in diameter. Earth-skimming Method is used and if the Chrenkov light can be detected from behind a mountain, the oscillation of νμ → ντ can be proved. Mei-Fong farm of National Taiwan University is our first domestic site. The first field test took place in the summer of 2009.
We measured the night sky background in this field test. We used four MAPMTs and choose moonless nights to determine the incident photon flux behind the mountain.
