Collision Researches Using MeV Energy Heavy Ion Accelerators of Kyoto University

Abstract

Current status of MeV energy heavy ion accelerators of Kyoto university (Faculty of Engineering) is reported. Two types of ion accelerators with terminal voltages 2.5 MV (VdG) and 1.7 MV (Tandem) are utilized for both fundamental and application researches covering atomic collision physics, materials science and element analysis. A brief introduction is given of experimental techniques, developed in our laboratory, concerning multi-coincidence for 3D-imaging of molecular fragmentation, liquid-in-vacuum for ion interactions with liquid targets and positron annihilation for in-situ observation of ion-irradiated materials.
