| 内容記述 | Since 1994, the HIMAC (Heavy Ion Medical Accelerator in Chiba) accelerator complex has delivered carbon ions for cancer therapy and other heavy-ions for basic and applied research. One of the objectives of HIMAC is to develop new technologies in heavy-ion therapy and related research. Even in the carbon cancer therapy, it is very important to investigate the behavior of free radicals. For the purpose, the ion-beam pulse radiolysis with the time resolution of microsecond has been carried out at HIMAC. In order to improve the time resolution to nanosecond order, thus, we have studied the production methods of short-pulsed ion-beam. One of the methods is bunch rotation just after momentum cooling through the electron cooling method. In this method, the initial momentum of ion beam in a storage ring is cooled down owing to the strong phase-space compression by the electron cooling, and the beam with the low momentum spread is bunched and rotated by 90 degree in the longitudinal phase-space by applying RF-voltage. We have investigated this method experimentally in the HIMAC synchrotron by using the fully stripped Ar ions with the energy of 6 MeV/u. As a result, it was verified that the pulse length was compressed to less that 100 ns from around 400 ns without the momentum cooling. We will report the experimental result of the method. | |||||
