Segmented YSO scintillation detectors as a new $\beta$-implant detection tool for decay spectroscopy in fragmentation facilities

Abstract

A newly developed segmented YSO scintillator detector was implemented for the first time at the RI-beam Factory at RIKEN Nishina Center as an implantation-decay counter. The results from the experiment demonstrate that the detector is a viable alternative to conventional silicon-strip detectors with its good timing resolution and high detection efficiency for $\beta$ particles. A Position-Sensitive Photo-Multiplier Tube (PSPMT) is coupled with a $48\times 48$ segmented YSO crystal. To demonstrate its capabilities, a known short-lived isomer in ${}^{76}$Ni and the $\beta$ decay of ${}^{74}$Co were measured by implanting those ions into the YSO detector. The half-lives and $\gamma$-rays observed in this work are consistent with the known values. The $\beta$-ray detection efficiency is more than 80~\% for the decay of ${}^{74}$Co.
