| Outline of Final Research Achievements |
Towards realizing the next-generation neutrino oscillation experiment using
a high-intensity neutrino beam, a study of a radiatin-hard diamond detector was performed for practical use as a muon profile monitor. Several 0.5mm thick CVD single-crystalline diamond samples were obtained from the company, and the stability of the output signal against exposure of deep ultraviolet (DUV) rays and high intensity muons were studied. The stable output was seen after the 3-days continous DUV exposure. As for the high intensity muons, the signal reduction was seen for the exposure rate above 3E+7 particles/cm2/s, which is likely caused by the electron capture into the impurity level in the diamond. Further qualitative improvement of diamond is necessary for practical use under the extremely high-intensity radiation.
