| Abstract: | Very high-energy cosmic-ray muons penetrating through a mountain enable us to probe the internal structure of volcanoes. An improved cosmic-ray muon detection system comprising two segmented detectors with multiplicity cut of the soft components of cosmic rays was developed. The test measurement for the volcano Mt. Asama is described. This revised version was published online in August 2006 with corrections to the Cover Date. |
| Keywords: | cosmic-ray muon multiplicity-cut analysis |
