摘 要：Single-ion hit for studies of microscopic irradiation experiment is utilized with spatial accuracy of a few micrometers by means of heavy ion microbeam of several hundred MeV at the TIARA cyclotron. High spatial accuracy for the real-time position detection of single-ion hit is essential in irradiation experiments of biological cells. A CR-39 plastic track detector is generally used as a position detector of single-ion hit. The tracks formed on it after chemical etching are observed by microscope. This procedure takes more than an hour and limits efficiency of therefore strongly required, and various scintillators are examined so far. It is taken notice of photostimulated luminescence (PSL) of Al_2O_3:C in this study, which has accurate dose sensitivity ranging from 0.1 μGy to 10 Gy. Photostimulable sample are possible to be prepared by adjusting parameters such as the amount of implantation density of activators by means of the TIARA ion implanter and annealing condition.
