摘要：

A fast digitizing system was used as a new pulse height analysis system in nuclear spectroscopy applications. Input signals were processed by a computerized data processing system composed of a fast ADC (200MHz/10bit) and a UNIX workstation. Measurements have been made with a large volume HPGe detector and Co-60 gamma-ray source. Better energy resolution of 1.7 keV was obtained in this system, compared to 2.0 keV in the conventional system with shaping circuit of 6 musec time constant. Digital analysis of the pulse waveform has been examined. The selection of convex waveforms gives an improved peak-to-Compton ratio. This technique has a potential possibility to analyze individual signals more precisely and to be used as an advanced signal processing method.
