| Outline of Final Research Achievements |
By using new-type fast photomultiplier tubes, a new Cherenkov Time-of-Flight detector has been developed for measurements of heavy ions. Is has been tested at the heavy-ion synchrotron facility HIMAC in National Institute of Radiological Sciences, Japan, under various conditions of number of Cherenkov photons by changing beam species and energies. As a result, we achieved the initial target value of the resolution σ ≦ 10 ps. Furthermore, applying various improvements, we have accomplished the best value of the time resolution σ = ～5 ps (including system resolution) for 400A MeV 132 Xe beam. After this, we will improve this detector on the points of lager sizes and versatility.
