Introduction to Neutron Response

What is/are Neutron Response?

Neutron Response - We report results of fast neutron response in plastic scintillator (PS) bars from deuterium-deuterium (D-D) and deuterium-tritium (D-T) reactions using Purnima Neutron Generator Facility, BARC, Mumbai. ^[1] The neutron response is determined using the pulse shape discrimination charge comparison technique which can clearly identify both the (n, α ) and (n,p) reactions in the material. ^[2] The dynamical energy over temperature scaling in the neutron response throughout the Brillouin zone and the temperature dependence of the static uniform susceptibility, indicate that temperature is the only energy scale in the criticality. ^[3] Different parameters were optimized based on Monte Carlo code to flatten the neutron response energy distribution, over a wide energy range, from a few eV’s to 1 GeV without significant changes in the response observed, and a deviation less than 15. ^[4] However, the neutron dose rate and the neutron response are strongly dependent on the distance between the detector and the source and on the surrounding environment. ^[5] For the cases presented here the MTS-N TLD detector seems to be the most optimal tool for dose measurements within the target volume, while the MCP-N TLD detector, due to an interplay of its enhanced thermal neutron response and decreased detection efficiency to highly ionising radiation, is a better choice for the out-of-field measurements. ^[6] This work characterizes the fast and slow neutron response of EJ-254, an organic plastic scintillator with 5% natural boron loading by weight. ^[7] A linear spin wave theory with a single Heisenberg interaction on the honeycomb lattice, including both transverse and longitudinal channels of the neutron response, reproduces all of the key features in the spectrum. ^[8] The objective of this study is to simulate the FNTD fast neutron response to: (i) assess and understand the performance of the existing neutron dosimeter design (Landauer Inc. ^[9] Both thermal neutron scattering as well as low energy resonance broadening involve processes where incoming neutron responses are lattice dependent. ^[10] Determination of the neutron response function is essential for measuring the energy of neutrons emitted from natural and artificial neutron sources and nuclear reactions. ^[11] This part of the book has a nice section on sum rules, and it discusses other properties of the neutron response like detailed balance, linking it with the general properties of response theory. ^[12] The geometric structure of these neutron filters was optimized by a Monte Carlo calculation to make the neutron response similar to the ICRP-74 rem-response. ^[13] The effects of disorder and finite lifetime, which are practically indistinguishable in the linear optical or neutron response, manifest in dramatically different fashion in the 2D spectra. ^[14] Both experimental data and simulation results suggest that the large-area neutron response to drip irrigation is insignificant in our specific case using a standard CRNS probe. ^[15] The neutron response function of the Bonner spectrometer is of essential importance for its neutron spectrum unfolding procedure and is directly related to the quality of the unfolded spectrum. ^[16] However, the model fails to describe the momentum dependence of the excitations at high energy transfers, where the neutron response decays faster with momentum than the Co$^{2+}$ form factor. ^[17]

neutron response function

Determination of the neutron response function is essential for measuring the energy of neutrons emitted from natural and artificial neutron sources and nuclear reactions. ^[1] The neutron response function of the Bonner spectrometer is of essential importance for its neutron spectrum unfolding procedure and is directly related to the quality of the unfolded spectrum. ^[2]
