Neutron diffraction at simultaneous high temperatures and pressures, with measurement of temperature by neutron radiography

Mineralogical Magazine, 2001
AbstractThe commissioning and operation of apparatus for neutron diffraction at simultaneous high temperatures and pressures is reported. The basic design is based on the Paris-Edinburgh cell using opposed anvils, with internal heating. Temperature is measured using neutron radiography. The apparatus has been shown in both on-line and off-line tests to

Neutron Diffusion in a Temperature Gradient

Nuclear Science and Engineering, 1962
>The space energy distribution of neutrons diffusing in a source-free, nonabsorbing medium possessing a temperature gradient is obtained by solving the appropriate Boltzmann equation to a second order approximation using the expansion technique of Chipman and Enskog.

Temperature of neutron stars

International Journal of Modern Physics D, 2016
We start with a brief introduction to the historical background in the early pioneering days when the first neutron star thermal evolution calculations predicted the presence of neutron stars hot enough to be observable. We then report on the first detection of neutron star temperatures by ROSAT X-ray satellite, which vindicated the earlier prediction

Temperature Shift of Neutron Resonances

1986
Temperature-induced shift of neutron resonances have been experimentally observed studying low-energy resonances of 103Rh, 109Ag, l61Dy and l63Dy with a time-of-flight spectrometer at the Dubna pulsed reactor The shifts are regarded as an analogue to the second-order Doppler effect in Mossbauer gamma-ray spectroscopy.

High-temperature neutron dosimeters

Nuclear Instruments and Methods, 1972
Abstract Preparation methods have been established for certified and pure refractory neutron flux detectors. The classical powder mixing, pressing, sintering, and mechanical finishing operations have been refined for Al 2 O 3 containing 1% CoO and MgO containing 1% CoO.

Temperature Equilibrium of C-Neutrons

Nature, 1937
THE slow neutrons leaving a block of paraffin wax, containing a source of fast neutrons, mostly possess thermal energies. The existence of such thermal neutrons has been established by the discovery1 that the temperature T of the paraffin has an influence on the activities induced in various elements.
