Outline of Final Research Achievements

Initially bunched ions extracted from short-pulse-laser induced plasma that is synchronized with the RF acceleration phase can eliminate the buncher section of an RFQ and useful for an advanced accelerator design.
Among subjects to be solved, the selection of the irradiation target and R&D on the measurement method were the key issues. As to the irradiation target, solid targets, which are easy for handling, produced plasmas with too high densities and no useful results were obtained. Gas jet target was finally chosen and pulse gas valve using a piezoelectric element was fabricated for the experiments.
With a proper phase relation between laser shot timing and the RF electric field phase, we could observed bunched ions with a probe located close to the production point and succeeded to prove the principle.
