摘要：
A novel method to measure beta-gamma coincidences using a phoswich detector with state-of-the-art pulse shape discrimination techniques has been investigated. A thin CaF2(Eu) and thick NaI(Tl) crystal phoswich detector has been built and tested using gamma and beta test sources as well as xenon gas. The two types of radiation are distinctly seen in the signal processing electronics based on pulse shape analysis. Preliminary results indicate that it will be difficult to achieve sufficient discrimination of the pulse types in application to beta-gamma coincident counting.
