“…Various methodologies have been explored for measuring neutrons, utilizing scintillation detectors due to their specific qualities such as very fast response, high Brazilian Journal of Development, Curitiba, v.10, n.4, p. 01-10, 2024 neutron efficiency and response, neutron-gamma discrimination. Notable contributions in this domain have been studied by [4][5][6][7][8] who have employed scintillators, together with the pulse shape discrimination method for neutron/gamma discrimination effectively. This work focuses on measuring the production of secondary neutrons from a water phantom irradiated by a medical proton accelerator.…”

This study investigates the production of radiation-induced secondary neutrons resulting from the irradiation of a water phantom by a medical proton accelerator. Measurements were conducted using a 2-inch by 2-inch stilbene scintillation detector. To distinguish between neutrons and the gamma background, we applied a pulse shape discrimination technique utilizing the charge integration ratio (Qratio) method. Our analysis carries out for three proton beam energies: 76 MeV, 80 MeV, and 132 MeV. The findings demonstrate the feasibility of using a stilbene scintillator detector in conjunction with the Qratio method for the measurement and analysis of secondary neutrons, which are detectable in significant quantities.

“…Hence, a lot of research has been carried out to implement the traditional methods in digital domain [7,8] and to develop novel methods in a digital framework. Some novel time domain methods are pulse gradient analysis (PGA) [9], simplified digital charge collection (SDCC) [10], reference pulse method [11], triangular pulse shaping method [12], etc.…”

It has been observed that the discrimination performance of the wavelet transform method strongly depends on definition of discrimination parameters. These parameters are usually obtained from a combination of scaling functions at different scales, which represents the energy density of the wavelet coefficients. In this paper, the discrete wavelet transform (DWT) at minimum possible values of scale was investigated. Novel pulse shape discrimination parameters have been proposed for neutron and gamma discrimination in a mixed radiation field and tested with modeled pulses. The performance of these parameters was also validated in terms of quality of discrimination using experimental data of mixed events from an AmBe source collected with BC501 liquid scintillation detector. The quality of discrimination was evaluated by calculating a figure of merit (FOM) with all parameters under same experimental and simulation conditions. The FOM obtained with the proposed novel parameters was also compared with the charge comparison method. The proposed parameters exhibit better FOM as compared to the charge comparison method when high levels of noise are present in the data.
