Abstract
The performance of the extrapolated leading edge type of time pickoff used with a large HPGe coaxial detector is studied. The time resolution using such a type of time pickoff has been found to be comparable with that obtained by employing the commonly used amplitude and rise-time compensation technique. For a BaF 2−HPGe (27% efficiency) coincidence setup, the values of FWHM and FWTM are 3.2 and 7.0 ns, respectively, when 60Co photopeaks are selected.
