Abstract
A nuclear beam of extremely low intensity was realized by accelerating decay particles from heavy radioactive nuclei through an AVF cyclotro n. Alpha particles from a Am-241 source (3.3 X 10(6) Bq) were accelera ted up to 30 MeV with a cyclotron starting from a proper radius. The w eak beam of alpha particles was detected and its energy and microscopi c time structure was analyzed. The count rate was attenuated down to 5 counts per minute which is only 1/20 of the value estimated from sour ce geometry and accelerator acceptance.
