Abstract
A customized leading-edge discriminator has been developed for picking up information on the position and the time for a planar-type segmented germanium detector. The discriminator consisted of three stages: a differentiating amplifier, a voltage comparator, and a mono-stable multivibrator. With the present discriminator modules, we examined spectral characteristics for the segmented germanium detector by using uncollimated 662-keV gamma rays. Anode energy spectra in coincidence with cathodes showed that better peak-to-total ratios could be obtained with increasing coincidence fold. Further, a salient feature of the exponential decay in the time difference spectrum between the anode and cathodes was observed to a fair extent.
