A heavy ion synchrotron complex, HIMAC, has been constructed for medical use at National Institute of Radiological Sciences (NIRS), Japan. The heavy ion therapy is adopted because it has the merits of the excellent dose localization and the high biological effectiveness on both aerobic and anaerobic cancer cells. The maximum energy of the HIMAC synchrotron is designed to be 800 MeV/u for light ions with q/A=1/2 so that the residual range of silicon ions reaches about 30 cm in human body. There are three treatment rooms two of which have a vertical and a horizontal beam line, respectively. The third treatment room is equipped with both beams lines. The beam tests of the accelerator system started in last November and is successfully completed in February. After about four months tests of the irradiation system including the biological experiments, the clinical trials started on June 21 using a 290 MeV/u carbon beam.
