| Research Abstract |
A real-time position detection of single-ion hit with spatial accuracy of a few micrometers is essential in irradiation experiments of biological cells.
In this study, the real-time detection system for single-ion hit was constructed by combining a prepared Al2O3:Eu sample and a luminescence detection device. The Al2O3:Eu have strong ion luminescence(IL) by adjusting implantation fluence of Eu as activator. The luminescence detection device, which is composed of confocal microscope and an electron-multiplier charge-coupled device camera, has a spatial resolution of 1 µm. The device detects IL from the prepared Al2O3:Eu by spot irradiation of 260 MeV-Ne at a fluence rate of more than two hundreds ions per second.
