Compton continuum suppression by pulse shape analysis

Abstract

The authors present experimental results on suppressing and flattening the Compton continuum by digital and analog pulse shape analysis. A doubling of the Cs-peak-to-Co-Compton ratio and a nice flattening of the Compton edges were achieved by pulse shape analysis in rejecting pulses from the peripheral regions of the Ge-detector, where the Compton scattering followed by the gamma escaping from the detector is most common. The pulse shape analysis technique may also offer a way to construct a position-sensitive Ge-detector. >
