Research on Fission Chamber Signal Simulation of Wide-range Nuclear Instrument System

To establish an input signal to debug a digital wide-range nuclear instrument system (NIS) prototype, the research of fission chamber signal simulation was covered in this paper, which was composed of the simulation study of a pulse signal and a fluctuating current with pulse pile-up, and the signal output of the simulation results. The research is the first step to design and develop the algorithm of wide-range NIS prototype.
