Possibility of Accelerating the Light Nucleus by KEK Proton Synchrotron

An accelerating method of the light nuclei with charge-mass ratio of 1/2 by use of the proton synchrotron system of KEK, is described. The description is mainly on the ring accelerator system and the ion source is excepted. The poor manpower and fund were large constraint conditions to find the acceleration method. As the velocities of the extracted nuclear beam from the linac and from the booster synchrotron are half the present proton´s in this method, wider range of accelerating frequency than the present one is necessary for the ordinary acceleration method in the main ring synchrotorn. To avoid much modification in r.f. system coming from the extension of frequency range, a method called multi-stage acceleration is applied.
