| Outline of Final Research Achievements |
Thanks to the very high power accelerator such as the MEGA-WATT-class proton machine, prismatic results are expected for the recent high-energy/nuclear experiments. On the other hand, the radiation hardness of particle/radiation detectors is becoming a very important and urgent issue. The diamond-base semiconductor detector has gotten many attentions due to its strong radiation tolerance.
In this research, we aim to operate a diamond detector specialized in only radiation counting, while sacrificing the accuracy of energy measurement, by using an inexpensive polycrystalline diamond instead of mono-crystal diamond which is difficult to manufacture and very expensive. By this idea, we succeeded in developing a new type of beam monitor in a high intensity proton accelerator.
