Development of Time Interval Analysis Nuclide Monitoring System Based on High-speed Data Acquisition Card
This thesis constructs a set of time interval analysis radionuclide monitoring device based on time stamp,which contains hardware parts such as composite crystal detector,nuclear signal analog processing circuit,high-speed data acquisition card with time stamp function,etc.The upper computer interface is developed based on the C#language,which obtains the statistical information of time interval distribution and realizes the monitoring of the concentration of the target radionuclide in the cascade decay.The experimental results show that the device is simple in structure,capable of extracting the nuclides to be measured under the condition of multi-nuclide mixed field,and has strong practical value.
