| Abstract;A new acceleration method for a tandem accelerator was designed and tested to obtain a high-intensity low-energy beam for an astro-nuclear experiment. The method uses accel-decel strong focusing. In a normal tandem accelerator the electric potential uniformly increases to the maximum voltage V, however, in the new method the potential goes up to V abruptly in a short length(=1/5 of the total length), then goes down to V/4 in the same short length, again goes up to V and down to V/4, and finally goes up to V. The beam is strongly focused due to alternating focusing and defocusing actions. The transmission of low-energy 12C beam was found to be an order of magnitude increased by this method.
