A radioactive 9C-ion beam, therefore, is considered to be very useful in cancer radiation therapy. To explore the potential importance of radioactive 9C-ion beams in cancer therapy, radiobiological experiments using a 9C beam supplied by the secondary beam line (SBL) at the Heavy Ion Medical Accelerator in Chiba (HIMAC), Japan were carried out.展开更多

It consists of 2 quadruple triplets and a perpendicular electric and magnetic field acting as a Wien filter. The total length of of the separator is 5. 1 m, and the designed maximum electric and magnetic fields are 15 kV/cm and 5 kG, respectively.展开更多
