| Zusammenfassung |
| In order to investigate the complex nature of landslides triggered by
rainfall, dynamic muon radiography of the motion of the underground water
table is planned in a drainage tunnel drilled underneath an estimated fault
plane. However, the humidity inside the tunnel is almost 100%. In order
to suppress moisture effects, a scintillation counter with Cockcroft–Walton
photomultipler tubes (CW-MPT) was developed and tested at the observation
site located in Shizuoka Prefecture, Japan. The counter was stably operated
for 38 days without gain degrading. Based on the result, we constructed a
muon detection system with CW-PMTs at the same site and started operation
runs. In this work, the data from borehole-based water gauge measurements of
the underground water levels were analyzed and discussed. It was confirmed
that the comparison between muon and borehole data would be useful. |
