Abstract

In this research, we have studied a speed system for neutron flux estimation used in experimental works with radiation protection design and for applications where materials identification based on neutron backscattering is crucial. The most effective approach is neutron-gamma discrimination using the stilbene scintillator. We performed a discrimination with the charge integration technique. The data acquisition was implemented using a high sampling rate oscilloscope. Crystalline stilbene is an organic scintillator that is well-suited for fast neutron identification in environments with high gamma-ray-associated irradiation.
