Abstract
- We have tested the timing properties of several thin plastic scintillators (10-500 mu m) designed for the Rare-RI Ring project at the R I beam factory. The experiments were performed at the heavy-ion synchrotron facility, HIMAC (Heavy Ion Medical Accelerator in Chiba), using a Xe beam with an energy of 200 MeV/nucleon. The scintillation light was read Out by fast-timing photomultipliers through standard fishtail-shaped light guides. The resultant timing resolutions reached a few tens of picoseconds, which satisfied our requirement for the project. We also measured charge-state distributions for Xe42+ and Fe20+ ions penetrating carbon foils of 10-500 mu g/cm(2) thickness. The results were compared with a theoretical model calculation for charge-state evolution. (c) 2008 Elsevier B.V. All rights reserved.
