2010年下半年开展的微堆数字化物理启动装置的研制工作,该工作的主要目的是要建立1套数字化物理启动装置,以替换现有的以模拟信号为主的物理启动装置。此装置相对于现有的物理启动装置的主要优点为:以图形的形式实时显示次临界外推和超临界内插结果。课题的主要任务是:设计放大电路对来自于探测器前置放大的信号进一步放大,设计数据采集 In the second half of 2010, the development of a micro-stack digital physical start-up device was developed. The main purpose of this work is to establish a set of digital physical start-up devices to replace the existing physical start devices based on analog signals. The major advantage of this device over existing physical starters is the ability to display sub-critical extrapolation and supercritical interpolation results graphically in real time. The main task of the subject is to design the amplification circuit to amplify the signal from the preamplifier of the detector and to design the data acquisition
