Neutron Production and Temperature in ZETA
Nature, 1958IT is assumed that thermalization and high temperature have been achieved in ZETA1, although theoretical considerations demand a much longer period than that available for the process to take place2. This discrepancy between apparently observed and the theoretically expected thermalization time may be due to unknown processes occurring which speed up ...

Internal Neutronics-Temperature Coupling in Serpent 2
Nuclear Science and Engineering, 2014This paper describes the built-in calculation routines in the reactor physics code Serpent 2 that provide a novel method for solving the coupled problem of the power distribution, temperature distribution, and material property distributions in nuclear fuel elements.

Low-Temperature Neutron Moderation
Physical Review Letters, 1960Measurements on an energy level in the microwave spectrum of water are discussed. The inelastic cross section for scattering of 0.005 ev neutrons from HO/sub 1/2/ at room temperature was estimated to be 8 barns. (C.J.G.)

On the growth of temperature within neutron stars [PDF]
Astrophysics, 1979 Analytic expressions are obtained that describe the variation of the temperature in the degenerate layers of the shell of a neutron star with electron heat conduction. The relativistic expression is used for the coefficient of thermal conductivity, and a possible crystallization of the ions is taken into account. For a neutron star with solar mass of 1

Neutron Diffraction Study of Water At High Temperature
Europhysics Letters (EPL), 1992Neutron diffraction measurements on water at T = 523 K are presented. The comparison with room temperature data shows an evident weakening of the tetrahedral coordination. This effect has been accurately simulated by an ensemble of polarizable water molecules, interacting via the NEMO (Non Empirical Molecular Orbital) potential model.

Neutron scattering at nK temperatures
Neutron News, 1991Abstract The study of nuclear magnetic order in Copper is the most ambitious and difficult neutron scattering experiment ever performed at Ris⊘. Beside expensive hardware, approximately 50man-months of scientific work, 24 months of beam time and 10000 litres of liquid He had to be invested before we could even expect to discover whether the experiment ...

Effects of temperature on the structure of neutron stars at high temperature
General Relativity and Gravitation, 2017In Newtonian physics, higher temperature leads to higher thermal pressure, which provides stronger support against the gravitational contraction of stars. However, in the temperature range of tens of MeV involved in the evolution of a proto-neutron star or a higher massive neutron star, the effects of temperature are richer.

Low temperature neutron irradiation of niobium
Scripta Metallurgica, 1976A study was made to determine the effect of low temperature neutron irradiation and post-irradiation annealing on the yield stress of low and intermediate oxygen content niobium. The results are compared with previous results to determine the type of neutron-produced defect that causes the changes in the yield stress. 12 references. (JFP)

A low-temperature Weissenberg camera for neutrons
Journal of Applied Crystallography, 1981The construction and performance of a neutron Weissenberg camera for temperatures down to 4 K is described. Exposure times are similar to the X-ray case. The background from the cryostat walls can be eliminated. Examples of applications in the fields of magnetic structures which are incommensurate with their chemical unit cells, crystallographic phase ...
