Investigation of the Status of Unit 2 Nuclear Reactor of the Fukushima Daiichi by the Cosmic Muon Radiography
Hirofumi Fujii, Kazuhiko Hara, Shugo Hashimoto +19
We have investigated the status of the nuclear debris in the Unit-2 Nuclear Reactor of the Fukushima Daiichi Nuclear Power plant by the method called Cosmic Muon Radiography. In th…
Investigation of Unit-1 Nuclear Reactor of the Fukushima Daiichi by Cosmic Muon Radiography
Hirofumi Fujii, Kazuhiko Hara, Kohei Hayashi +11
We have investigated the status of the nuclear fuel assemblies in Unit-1 reactor of the Fukushima Daiichi Nuclear Power plant by the method called Cosmic Muon Radiography. In this…
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…
Development FD-SOI MOSFET amplifiers for integrated read-out circuit of superconducting-tunnel-junction single-photon-detectors
Kenji Kiuchi, Shinhong Kim, Yuji Takeuchi +28
We proposed a new high resolution single photon infrared spectrometer for search for radiative decay of cosmic neutrino background(CB). The superconducting-tunnel-junctions(STJs…
