M. Taro Kusagaya (Earthquake Research Institute, University of Tokyo)18/04/2012 09:00Technical developments for muon and neutrino imagingPosterWe will present a real-time monitoring system for cosmic-ray muon radiography as an application of a readout module developed by T. Uchida et al [1,2]. The readout module was developed originally for probing the internal structure of volcanoes in 2008 [3]. Its features are small in size, low power consumption, and the capability to access remotely via Ethernet. The current statistics data of...Go to contribution page

M. Ryuichi Nishiyama (Earthquake Research Institute, University of Tokyo)18/04/2012 09:00Applications of muon imaging in volcanology; multi-probe structure study of volcanoesPosterWe have developed a method of analyzing gravity and muon-radiographic data for resolving a three-dimensional density structure of a volcano. In the method, we search for a density structure that explains the muon and gravity data by using a linear inversion scheme. As a demonstration, we applied this method to Mt. Showa-Shinzan lava dome, Hokkaido, Japan. At this site, muon observation...Go to contribution page

Hiroshi Suenaga (Central Research Institute of Electric Power Industry)18/04/2012 09:00Applications of muon imaging in civil and industrial engineeringPosterA research for high level radioactive waste disposal should investigate geological structure and saturation change of rock mass around a disposal cavern. In the CO2 geological storage and the underground storage of crude oil, natural gas or liquefied petroleum gas (LPG), it is necessary to monitor an upward migration of a gaseous fluid which is stored in underground. For an investigation of...Go to contribution page

Prof. Hiroyuki Tanaka (University of Tokyo), Dr Kuniyoshi Takamatsu (JAEA)18/04/2012 09:00Applications of muon imaging in civil and industrial engineeringPosterThe Fukushima Daiichi nuclear disaster is a series of equipment failures and nuclear meltdowns, following the T¯ohoku earthquake and tsunami on 11 March 2011. We present a new method for visualizing nuclear reactors. Muon radiography based on the multiple Coulomb scattering of cosmic-ray muons has been performed. In this work, we discuss experimental results obtained with a cost-effective...Go to contribution page

Dr Akira Sannomiya (Electric Power Development)18/04/2012 09:00Applications of muon imaging in civil and industrial engineeringPosterIntroduction The technology that enables us to observe the internal structure of a volcano and the city foundation is being developed by utilizing the muon’s significant penetration power. From the possibility to use this technology for the surveillance inside a large-scale civil engineering structure, we are planning an experimental measurement. General Instruction A final target is...Go to contribution page

Prof. Hiroyuki Tanaka (University of Tokyo)18/04/2012 09:00Applications of muon imaging in civil and industrial engineeringPosterThe time resolution of dynamic muon radiography is defined by achieving the appropriate angular resolution, detection area, and cosmic ray muon flux (=70 muons/m2 sr sec). For example, at an angular resolution of 30 mrad, we need a detection area of 3.9 m2 to collect 100 muons in 8 hours for each bin. However, a space of this size in the correct position may be unavailable in an industrial...Go to contribution page
