Research overview:
Conventional radiation therapy modalities, X-rays, .gamma.-rays and electrons, have a dose distributions of monotonically decreasing in tissue. Protons and other heavy charged particles have Bragg peaks near the end of their ranges, wheretheir energy transfers are concentrated, so that they are effective for cancer therapy. Among them, proton beams have the best dose distribution and have been effective clinically. In addition their accelerators are much smaller than that of other heavy particles. Since it is becoming clear that the next modality will be protons, R&D of a dedicated proton accelerator and beam transport system are being continued.
