| Outline of Final Research Achievements |
We studied a beam background monitor for the Belle II experiment. For the background monitor, we developed the diamond detector with a high charge-correction-efficiency. Radioactive source measurement and I-V curve measurement were conducted to determine the suitable specification of the diamond detector. And, using the FLUKA simulation output, we succeeded to calibrate between the measured current and the irradiated dose. With commissioning beams of SuperKEKB, we estimated the performance of the developed diamond detectors. As a result, we confirmed excellent performance of the detector, and feasibility to use them as the Belle II background monitoring system.
