| Research Abstract |
We carried out R&D for large Cherenkov telescope array. Here we developed such components as segmented mirrors, PMT and readout electronics which satisfied the purpose. A budget had been approved for this experiment and also the big earth quake happened and it caused a radioactive pollution in the large area. We started R&D for gamma-ray camera using those components. The detector can detect the direction of gamma rays from 134,137Cs with the angular resolution of approximately 3 degree. The prototype can measure gamma-ray distributions of the area greater than 0.23μSv/h. The cost of the detector is as low as 1/10 of the other detectors.
