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 ...

No role for neutrons, muons and solar neutrinos in the DAMA annual modulation results [PDF]

, 2014
This paper summarizes in a simple and intuitive way why the neutrons, the muons and the solar neutrinos cannot give any significant contribution to the DAMA annual modulation results.

Thermal moderator-reflector assembly for HBS [PDF]

EPJ Web of Conferences
The thermal moderator is the key component in a research neutron source to convert the primary neutrons which typically have energies in the MeV regime into useful neutrons for investigations with energies well below 1 eV. In the case of a HiCANS as HBS,

Multiple Scattering Theory for Slow Neutrons (from thermal to ultracold)

, 1999
The general theory of neutron scattering is presented, valid for the whole domain of slow neutrons from thermal to ultracold. Particular attention is given to multiple scattering which is the dominant process for ultracold neutrons (UCN). For thermal and

Preparation of facilities for fundamental research with ultracold neutrons at PNPI [PDF]

, 2009
The WWR-M reactor of PNPI offers a unique opportunity to prepare a source for ultracold neutrons (UCN) in an environment of high neutron flux (about 3*10^12 n/cm^2/s) at still acceptable radiation heat release (about 4*10^-3 W/g).

New applications and developments in the neutron shielding

EPJ Web of Conferences, 2017
Shielding neutrons involve three steps that are slowing neutrons, absorption of neutrons, and impregnation of gamma rays. Neutrons slow down with thermal energy by hydrogen, water, paraffin, plastic. Hydrogenated materials are also very effective for the

Neutron spectroscopy with the Spherical Proportional Counter

, 2017
A novel large volume spherical proportional counter, recently developed, is used for neutron measurements. Gas mixtures of $N_{2}$ with $C_{2}H_{6}$ and pure $N_{2}$ are studied for thermal and fast neutron detection, providing a new way for the neutron ...

Fabrication of a superheated emulsion based on Freon-12 and LiCl suitable for thermal neutrons detection

Nuclear Engineering and Technology
This study develops superheated emulsion detectors that are both sensitive to fast neutrons, and thermal neutrons owing to the exergonic Li36(n,α)H13 capture reaction caused by the 6Li-containing compound dispersed throughout the gel-like medium.

Slab geometry type cold neutron moderator development based on neutronic study for Riken Accelerator-driven compact Neutron Source (RANS) [PDF]

EPJ Web of Conferences, 2020
Cold neutrons with energy less than several meV are good probes for material research, and they have been available on large neutron facilities, whereas it is not commonly available on compact accelerator-driven neutron source.
