A transfer instrument for neutron dosimetry

The International Journal of Applied Radiation and Isotopes, 1976
Abstract For neutron dosimetry, it is necessary to be able to separate the neutron and X-ray components that usually co-exist in the radiation field. Two instruments are in general required for this purpose and should ideally be transportable through the post.

Need for Neutron Diffraction Instruments

Science, 1999
The News Focus article by Robert F. Service “Wiggling and undulating out of an x-ray shortage” (27 Aug., p. [1342][1]) highlights the shortage of hard x-ray sources that has occurred after an explosion in demand from structural biologists. A greater shortage for U.S. structural biologists,

Instrumentation with polarized neutrons

Physica B: Condensed Matter, 2009
Abstract Neutron scattering with polarization analysis is an indispensable tool for the investigation of novel materials exhibiting electronic, magnetic, and orbital degrees of freedom. In addition, polarized neutrons are necessary for neutron spin precession techniques that path the way to obtain extremely high resolution in space and time. Last but

Instrumental neutron activation analysis of gallstones

International Journal of Radiation Applications and Instrumentation. Part A. Applied Radiation and Isotopes, 1990
Four kinds of gallstones from 40 patients have been analyzed for the presence of a total of 18 elements by instrumental neutron activation analysis. Of these elements, Ca, Mg, Fe, Co, Zn, Na, and Cl are found in the core of all types of stones. The differences in elemental composition of the various types of stones as well as the differences in the ...

Instrumentation for neutron spectroscopy

Spectrochimica Acta Part A: Molecular Spectroscopy, 1992
Abstract The basic principles of operation of most types of neutron spectrometers used by chemists are reviewed. The merits and constraints of each type is explained in terms of energy range, resolution, data rate and momentum transfer range so that the reader can understand why particular experiments are, or are not, done.

Balloon-Borne Instrumentation for Neutron Detection

Review of Scientific Instruments, 1950
A description is given of balloon-borne proportional counters and circuitry for telemetering and recording cosmic-ray neutron intensities. The preamplifier, amplifier, scaler, and trigger circuit described all use low drain directly heated battery-type tubes. Methods and reasons for pressurization of high voltage circuits are discussed.

A Digital Twin for Neutron Instruments

2023
Data from virtual experiments are becoming an extremely valuable asset for research infrastructures in a multitude of aspects and different actors: for instrument scientists to develop and optimise current and future instruments; for training external users in the usage of the instrument control system; for scientists in studying, quantifying and ...

Neutron interferometry instrumentation at MURR

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1998
Abstract During the last two decades more than 35 fundamental quantum interference experiments have been performed using the perfect-silicon-crystal neutron interferometer. About one-half of these experiments have been carried out at the University of Missouri Research Reactor Center (MURR).

Instrumental Neutron Activation Analysis of Kidney Stones

Biological Trace Element Research, 1990
Kidney stone samples of the types calcium oxalate, uric acid, and xanthine were analyzed for their elemental contents by neutron activation analysis to study both the elemental correlation and influence of element on stone precipitation processes. Elements, such as Al, Au, Br, Ca, Cl, Co, Cr, Fe, Hg, I, K, Mg, Na, Sb, Se, Sr, and Zn, were determined ...
