Cosmic-ray neutron transport at a forest field site: the sensitivity to various environmental conditions with focus on biomass and canopy interception [PDF]

Hydrology and Earth System Sciences, 2017
Cosmic-ray neutron intensity is inversely correlated to all hydrogen present in the upper decimeters of the subsurface and the first few hectometers of the atmosphere above the ground surface.

Thermal neutron intensity measurement with fission chamber in current, pulse and Campbell modes [PDF]

EPJ Web of Conferences, 2020
In thermal nuclear reactors, most of the power is generated by thermal neutron induced fission. Therefore, fission chambers with targets that respond directly to slow neutrons are of great interest for thermal neutron flux measurements due to relatively ...

Implications of Hyperon Pairing for Cooling of Neutron Stars [PDF]

, 1998
The implications of hyperon pairing for the thermal evolution of neutron stars containing hyperons are investigated. The outcome of cooling simulations are compared for neutron star models composed only of nucleons and leptons, models including hyperons,

Thermal conductivity of neutrons in neutron star cores [PDF]

Astronomy & Astrophysics, 2001
The diffusive thermal conductivity of neutrons in dense matter [$ \sim (1 - 8) \times 10^{14}$ g cm$^{-3}$] of neutron star cores is calculated. The contribution from neutron--neutron and neutron--proton collisions is taken into account. We use the transition probabilities calculated for symmetric dense nucleon matter on the basis of the Dirac ...

Fabrication and Characterization of K₂CeCl₅/⁶LiCl and CeCl₃/SrCl₂/⁶LiCl Eutectics for Thermal Neutron Detection

Crystals, 2022
In recent years, thermal neutron detection using scintillators has been used in a wide range of fields. Thus, the development of scintillators with a higher light yield, faster decay, and higher sensitivity for thermal neutrons is required. In this study,

Investigation on Neutron Flux Effect onto Irradiated Fuel Burn-up Stored in the Reactor TRIGA PUSPATI

Atom Indonesia, 2019
An investigation on the out-core neutron flux in the Reactor TRIGA PUSPATI is carried out in this work to determine whether the thermal and/or fast neutron from the core would cause burn-up of the irradiated fuel stored in the same vicinity of the ...
