摘要
从晶体管直流增益与受照中子注量呈线性关系出发,使用晶体管作为辐照效应参数在线测量探测器,研制了以计算机、矩阵开关、多通道同步采集卡、任意波形发生器以及测试转接板等硬件为基础,基于LabVIEW平台的辐照效应测试系统。在CFBR-Ⅱ堆和钴源上,分别利用"瞬态和稳态不同辐照模式的损伤异同性试验"和"中子、γ不同辐照顺序的损伤等效性试验"进行了测试系统验证,实现了瞬态和稳态辐照下样品效应参数的实时测量。结果表明,研制的辐照效应在线测试系统可同时满足瞬态和稳态效应测量的指标要求,具有较高的可靠性和稳定性。
An radiating effect test system was established which based on the linear relationship between the reciprocal of current gain and the neutron flux,and the transistors with good similar parameters have been employed as radiating effect monitors.The hardware of this system consisted of computer,matrix switch,multicenter synchronous collector,function waveform generator and test board;while the software was built up by Labview program.The validity tests were performed at CFBR-Ⅱ reactor and cobalt radiant point.The test of radiating effect parameters was actualized by this system,and the changes of radiating effect parameters in the transient and steady radiating field with neutron fluence were obtained.
