在堆物理实验室中采用在线计算技术,是实现实验手段现代化的一个重要方面。本文叙述了零功率反应堆物理实验室中子通量在线测量系统的研制。该系统包括 DBL-1 型联动定标器;经过改装的 DJS-7 型小型计算机;自行设计制造的直接输入通道和在线系统的管理程序;中子通量测量程序等部份。一年多来的运行表明:该中子通量在线测量系统实现了从测量到实验数据处理的自动化。不仅能快速给出多种实验结果,而且能对实验过程中出现的奇异现象及时加以纠正,从而大大提高了实验精度。
The use of online computing technology in reactor physics labs is an important aspect of the modernization of experimental methods. This article describes the development of zero-power reactor physics laboratory neutron flux on-line measurement system. The system includes DBL-1 linkage calibrator; modified DJS-7 small computer; self-designed direct input channels and online systems management procedures; neutron flux measurement procedures and other parts. More than a year of operation has shown that this neutron flux online measurement system automates the process of measurement to experimental data processing. Not only can quickly give a variety of experimental results, but also to the singular phenomena in the experimental process in a timely manner to be corrected, thus greatly improving the experimental accuracy.
