A Detection Method of Atmospheric Neutron Profile for Single Event Effects Analysis of Civil Aircraft Design

Atmosphere, 2022
High-energy particles such as neutron act as serious threats to electronic equipment on board aircraft via Single Event Effects (SEE), but atmospheric neutron flux profile which could cover civil aviation altitude is rarely observed.

The effect of craters on the lunar neutron flux [PDF]

Journal of Geophysical Research: Planets, 2015
AbstractThe variation of remotely sensed neutron count rates is measured as a function of cratercentric distance using data from the Lunar Prospector Neutron Spectrometer. The count rate, stacked over many craters, peaks over the crater center, has a minimum near the crater rim, and at larger distances, it increases to a mean value that is up to 1 ...

Neutron flux intercomparison at NBS

Journal of Research of the National Bureau of Standards, 1978
National Bureau of Standards (NBS) participation in an International Bureau of Weights and Measures (BIPM) sponsored neutron flux intercomparison is described. The efficiencies of two transfer instruments, a gas-filled 3He proportional counter and a BF3 counter imbedded in a polyethylene sphere, were determined at neutron energies of 250 keV and 560 ...

Optimization and analysis of neutron distribution on 30 MeV cyclotron-based double layer beam shaping assembly (DLBSA)

Ядерна фізика та енергетика, 2019
Design and optimization of double layer Beam Shaping Assembly (DLBSA) has been conducted using the MCNPX code. The BSA is configured to comply with such a construction having typically a double moderator, a reflector, a collimator, and a filter.

Upsampling Monte Carlo neutron transport simulation tallies using a convolutional neural network

Energy and AI, 2023
The physical quantities calculated by nuclear reactor Monte Carlo simulations are typically recorded on a grid of two or three spatial dimensions and one dimension of neutron energy. Because of this, increasing the resolution of the calculated quantities

Data Acquisition System Prototype of the ITER Diagnostic Divertor Neutron Flux Monitor Testing at Research Nuclear Facilities [PDF]

EPJ Web of Conferences, 2021
The Divertor nuclear flux monitor (DNFM) is one of the ITER neutron diagnostics. This diagnostic consists of the three same subsystems. Each subsystem concludes the detector module with fission chambers (FCs) and the data acquisition system (DAQ).

High-accuracy determination of the neutron flux in the new experimental area n_TOF-EAR2 at CERN

, 2017
.A new high flux experimental area has recently become operational at the n_TOF facility at CERN. This new measuring station, n_TOF-EAR2, is placed at the end of a vertical beam line at a distance of approximately 20m from the spallation target.

On Controllability of Neutron Flux Distribution [PDF]

Journal of Nuclear Science and Technology, 1968
As a prerequisite to the optimal control of the neutron flux distribution of large reactors, the controllability of the flux distribution is invenstigated. The distributed parameter system is reduced to a lumped parameter system by means of truncated modal expansion. In a one dimensional reactor, any number of modes are controllable by a single control
