Abstract: 
A novel system has been developed to detect simultaneous double -alpha emission from purified and weightless sources. The system includes the collection of 224 Ra low -energy recoils in purified helium buffer gas from the decay of 228 Th. The recoil products are thermalized and collected in a cryogenic buffer gas cell and extracted into an RF-ion guide for mass selection. The mass -separated ions are implanted at low kinetic energy into a thin carbon foil placed between two large -area double -sided silicon strip detectors to observe correlated alpha -particle emission. The apparatus is described in detail, including insights into its experimental performance.
