Temperature measurement by neutron resonance radiography

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1989
Abstract We present a new method of data analysis for determination of temperature from the Doppler broadening of neutron resonance absorption cross sections. The method is model independent and simple to use. It has been applied to measurements on samples of rhenium and tantalum and has given temperatures to an accuracy better than ±1°C.

Neutron temperature measurements with 176Lu

Journal of Nuclear Energy. Part A. Reactor Science, 1959
A relative calibration of the Lu/sup 176/(n, gamma y) reaction is reported. It was found that the Lu/sup 176/(n, gamma ) reaction is potentially capable of measuring neutron temperature in the 0 to 110 deg C range to about 5 deg C. (C.J.G.)

High Temperature Neutron Diffraction Furnace

Review of Scientific Instruments, 1966
An induction transformer furnace for a neutron diffractometer is described. This furnace has been used for the examination of refractory carbides by neutron diffraction at temperatures up to 2500°C.

On the growth of temperature within neutron stars

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 Capture Data at Stellar Temperatures

Reviews of Modern Physics, 1965
Neutron capture cross sections are averaged over Maxwell-Boltzmann neutron distributions for temperatures pertinent to slow nucleosynthesis ($s$ process) in red giant stars. Such cross sections, together with isotopic abundances, provide the major quantitative experimental tests of the theory.

Influence of Temperature on the Groups of Slow Neutrons

Nature, 1936
WE have investigated the influence of temperature on the activation of silver by slow neutrons, separating the effects due to the groups A, B and C as defined by Amaldi and Fermi1. The arrangement used is shown in plan in Fig. 1. Absorbers of cadmium (0.258 gm./cm.2) and silver (0.077 gm./cm.2) were employed to separate the groups, and the use of a ...
