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.

在生物细胞辐照实验中，实时检测空间精度为几微米的单离子轰击位置是必不可少的，本研究将制备的Al_2O_3：Eu样品与发光检测装置相结合，构建了单离子轰击实时检测系统。通过调节Eu作为激活剂的注入剂量，Al_2O_3：Eu具有较强的离子发光。该发光检测装置由共焦显微镜和电子倍增器电荷耦合器件组成，空间分辨率为1微米，用260 MeV-Ne激光以每秒200多个离子的注量率从制备的Al_2O_3：Eu中检测离子。
