- 概要：
The IceCube Neutrino Observatory at the South Pole has been completed
in December 2010.
The primary aim of this observatory is to observe high energy
neutrinos from astorphysical
origins such as GRBs and AGNs. The telescope is deployed in the
glacial ice at 2 km depth
from the surface. It consists of approximately 5,500 optical modules
and detects Cherenkov light
from secondary particles that are derived from a neutrino.
I will introduce our telescope and the latest results mainly from the
construction phase.
I will focus especially on the extremely high energy neutrino (E >
10^17 eV) search.
Those neutrinos are inevitably generated from extremely high energy cosmic rays
(E > 5x10^19 GeV), therefore, can shed light on the origins that are
still not yet revealed
completely.
