  • Pulsed neutron detector converts neutron fluence rate into random weak current pulse signal. Due to the particularity of this signal, nuclear measurement equipment generally requires reactor tests to verify the actual detection performance. Because of the research method by reactor test costs a lot and has time limit, this paper, based on a typical pulsed neutron detector such as boron-coated proportional counting tube, studies a pulsed detector signal model and its nuclear signal generator implementation scheme. The characteristics of each key part are verified through simulation. The verification results show that: the proposed nuclear signal generator scheme can generate a sequence of time intervals satisfying the exponential distribution, the single current pulse shape is similar to the detector and the amplitude can vary randomly in a uniform distribution.
