摘　　要：本实验尝试将Pixie-Net数字化仪用于β-γ符合测量实验,替代复杂的传统电子学仪器装置,简化实验操作.测量结果表明:使用Pixie-Net数字化仪测量得到的放射源活度与理论值误差小于5%,好于基于传统电子学的结果.在β-γ符合测量实验中使用Pixie-Net数字化仪替代传统电子学仪器装置的方案切实可行.We attempt to use the Pixie-Net digitizer for the β-γ coincidence experiment in order to replaces complex traditional electronics and then to simplify experimental equipment.The measurement results show that the relative error between the measured activitivity using the Pixie-Net digitizer and the theoretical value is less than 5%,which is much better than the results with traditional electronics.It is feasible to replace traditional electronic instrument devices by the Pixie-Net digitizer.
