One of the most frequently observed random processes in nuclear experiments is the Poisson process. Due to the dead time effect of detection systems, the experimental process is different from the Poisson process. In this work, based on stochastic methods, a nuclear detection system is identified. The BF3 detector is a typical pulse mode detector. In this research, a typical BF3 detector is selected to implement the above method. Observed pulses at the detector output in the time domain were measured and analyzed using stochastic fluctuations analysis. In experiments such as measurements related to zero-power reactor noise theory, the transfer function of the detection system itself also affects the obtained results. Therefore, knowledge of the transfer function of the detection system used in these experiments is of particular importance. Also, in measurements where it is necessary to correct the detection system dead time, the specificity of the transfer function can provide valuable information about the effects of dead time. This study investigates the transfer function of a typical neutron detection system based on BF3.
