4πβ(PS)-4πγ(GE) list-mode coincidence counter and its applications
چکیده انگلیسی
We developed a 4πβ-4πγ counter composed of a 4π plastic scintillation detector and a well-type Ge detector, employing digital coincidence counting and data storage in list-mode. In both of the β- and γ-channels, the amplified pulses from a linear amplifier feed the input channel of the digitizer directly via delay circuits. A signal from the peak-hold of each channel is fed to a sliding scale ADC (14 bits, 200 MHz clock) after peak detection and converted into 13 bit digital data, registered along with a time stamp and event channel allowing various data analysis to be implemented offline. When employing multiple gamma window settings, a weighted average of each apparent efficiency might be introduced to improve the efficiency functions. This idea was investigated along with reasonable estimates of the weighing factors, and activity measurements of 59Fe using this system are presented.
