Technique for fluence attenuation by acceleration of decay particles
Abstract
A nuclear beam of extremely low intensity was realized by accelerating decay particles from heavy radioactive nuclei through an AVF cyclotron. Alpha particles from a 241Am source (3.3 × 10 6 Bq) were accelerated up to 30 MeV with a cyclotron starting from a proper radius. The weak beam of alpha particles was detected and its energy and microscopic 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 source geometry and accelerator acceptance.
