Imaging the Inner Structure of a Nuclear Reactor by Cosmic Muon Radiography

Hirofumi Fujii, Kazuhiko Hara, Shogo Hashimoto +15

We studied the inner structure of the nuclear reactor of the Japan Atomic Power Company (JAPC) at Tokai, Japan, by the muon radiography. In this study, muon detectors were placed o…

Search for Radiative Decays of Cosmic Background Neutrino using Cosmic Infrared Background Energy Spectrum

Shin-Hong Kim, Ken-ichi Takemasa, Yuji Takeuchi +1

We propose to search for the neutrino radiative decay by fitting a photon energy spectrum of the cosmic infrared background to a sum of the photon energy spectrum from the neutrino…
