Outline of Final Research Achievements

Charged particle detectors were fabricated using the synthetic single crystal
diamond grown by CVD for the TOF measurement at the high-intensity heavy-ion beam line. The diamond detector showed the high-speed response more than a silicon charged particle detector and a plastic scintillator. Additionally, the superior radiation hardness was also shown. The detector was able to measure an energy spectrum of incident ions because the detector was made from the high quality single crystal. We also fabricated a mosaic-detector using four single crystal CVD diamond detectors for expansion of the active area.
