摘要
介绍了脉冲时间序列采集器(TSA)的研制及实验验证。该仪器采用FPGA和DSP技术实现了三通道并行、最高定时精度5ns、最高计数容量109的脉冲序列采集存储。根据Rossi-α原理编制软件算法实现了在线和离线测量。该仪器应用于核装置瞬发中子衰减常数测量的实验验证,测量结果与Rossi-α测量结果一致。
This paper introduced the development and verification of the pulse time sequence acquisition (TSA) equipment, which achieved the 3 channel parallel input, 5ns timing precision, totalling 109 counts pulse time sequence acquisition and storage based on the FPGA and DSP techniques, and realized the on-line, off-line Rossi-α analysis measurement. The equipment was applied for verification of the prompt neutron de- cay constant measurement and the results are consistent with the traditional Rossi-α measurement system.
