Status of the HIMAC Injector

چکیده
At NIRS-HIMAC, by the end of July 2000, 837 patients have already been treated using carbon beams. One of the recent developments is a smaller number of fractionation. Actual fractionation is 4 times per week for Liver, and is 9 times per 3 weeks for Lung. The required beam intensity has thus increased up to 300 eμA of C at the source and 2×10 pps of C at the isocenter. Furthermore, since the installation of the secondary beam (C and Ne) course for therapy is almost completed [1], the high intensity for primary beams is now a prior subject in the HIMAC system. Various ion species and stable operation are also being requested for basic studies. This report describes the recent improvements and developments in the HIMAC injector.

Commissioning and Performance of the HIMAC Medical Accelerator
Heavy ions show the excellent dose concentration especially at a position located deep in a human body. This character of heavy ions are well suited for the medical treatment of the cancer. A heavy ion synchrotron complex, HIMAC, has been constructed at NIRS for this purpose. The HIMAC accelerator consists of an injector linac, a couple of synchrotron rings, long and complicated beam transport ...

Since 1994 clinical trials have been performed successfully with carbon beam. To improve the clinical result further, new irradiation systems are under development such as a 3D-irradiation system and a verification system of range with positron emitter. There are also improvements on the accelerator performances. One is the wide range of ion species; the others are concerned with the machine de...
متن کاملSynchrotron Control System of Himac
HIMAC, Heavy Ion Medical Accelerator in Chiba, has been in operation for about 8 years. The control system of HIMAC synchrotron is now undergoing renewal and upgrade. As a medical accelerator in use, reliability and availability of the beam must not be compromised in HIMAC. We decided to change most computers of the system in a node-by-node way, over a couple of years. Among the replaced are: P...
