摘要：
A new decay station has been built for the ISAC facility at TRIUMF for the rapid and reliable characterization of radioactive ion beam (RIB) compositions and intensities with the capability of simultaneously collecting alpha, beta, and gamma decay data from RIB with intensities between a few and approximate to 10(11) ions per second. It features user-friendly control, data acquisition, and analysis software. The analysis of individual decay time structures allows the unambiguous assignment of alpha and gamma lines even with substantial isobaric contamination present. The capability for accurate half-life measurements is demonstrated with the example of K-46. The coupling of the yield station to the laser ion source, TRILIS, allows the correlation of radiometric data with automated laser frequency scans. First results of in-source laser spectroscopy measurements on astatine are discussed. (C) 2014 AIP Publishing LLC.
