摘要
核能谱测量技术是研究核物理、重离子物理、高能物理及核应用技术的重要方法。在数字化核能谱测量系统中,核脉冲高速采样方法是其关键技术之一,而高速采样又受限于模数转换芯片(A/D芯片)的转换速度和数字化处理芯片的工作频率。主要研究如何通过利用FPGA和多片低速A/D芯片实现单片高速A/D的功能,并通过具体的实验验证了该方法的正确性和可行性,效果良好。
The technology of nuclear spectrum measurement is an important method for the research of nuclear physics, heavy ion physics, high energy physics and nuclear technology application. In the digital nuclear spec- trum measurement system, the high speed sampling method of nuclear pulse is one of the key technologies. And this method is restricted to the conversion speed of analog-to-digital chip (A/D chip) and the working frequency of digital processing chip. Article mainly research on how to implement a single high-speed A/D function by using FPGA and multi slow-speed A/D chips. And through the experiments verify the correctness and feasibility of the method, and the effect is good.
