A probing He{sup 0} beam for confined alpha particle measurement using a double charge exchange process is now under development. A proof of principle experiment for ground-state He{sup 0} beam production will be performed on a test stand. Several methods are developed to measure the metastable fraction of a He{sup 0} beam. A full-size strong-focusing He{sup +} source has been constructed and sufficient beam current was achieved with a beam size tolerable to be used on ITER.
