The ion accelerators, that were originally developed for the study of nuclear science have been used for medical purposes, and recently rather large-scale accelerator systems have been adapted for radiation therapy. Domestically, small-scale cyclotrons of 10 ~ 30 MeV for the production of radioisotopes are prominent examples of medical applications of accelerators. Another example is the proton a 230-MeV cyclotron that was recently installed at the National Cancer Center (NCC) for cancer therapy. Unlike isotope-production cyclotrons, cancer-therapy accelerators usually require more than one year of system verification to insure the proper formation of a beam for therapy, therapy beam formation, the safety of the system, and so on. In addition, unlike the beams for scientific users, therapeutic beams demand the precise control of the dose distributions tailored to various users, for which detector technologies developed for nuclear experiments can be applied.
