Instrumental Neutron Activation Analysis of Biological Samples
Biological Trace Element Research, 1990The elemental compositions of 18 biological reference materials have been processed, for 14 stepped combinations of irradiation/decay/counting times, by the INAA Advance Prediction Computer Program. The 18 materials studied include 11 plant materials, 5 animal materials, and 2 other biological materials.

Neutron Scattering Instrumentation
2009This chapter gives a short introduction into neutron scattering instrumentation to allow the non-specialist reader to acquire the basics of the method necessary to understand the technical aspects in the topical articles. The idea is not to go into details but to elaborate on the principles as general as possible.

In-Core Neutron Flux Instrumentation
IEEE Transactions on Nuclear Science, 1965A survey of the new work in the neutron monitoring of a nuclear power reactor is presented. The sensors have been moved into the reactor and the three modes of measurement necessary to cover the ten decades of the in-core neutron range from startup to rated power are described. The system specifications and life performance data are reviewed.

Instrumental Neutron Activation Analysis
Analytical Chemistry, 1960A system of instrumental neutron activation analysis in which no chemical operations are employed is described. It consists of neutron activation followed by gamma -ray spectrometry. Even with the relatively low thermal neutron flux available from a Van de Graaff accelerator photoneutron source (10/ sup 8/ neutrons sec/sup -1/ cm/sup -2/), useful ...

New concepts for neutron instrumentation
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2008With the progress made in establishing new coating and grinding techniques and the availability of new simulation tools significant progress has been made in increasing the performance of optical components being used for neutron instrumentation. These include passive components like honeycomb lenses, focusing collimators, devices using supermirror ...

X-Ray and Neutron Instrumentation
1987The basic procedure for any analysis involving structure determination, as outlined in Chapter 3–7, is to accumulate reliable experimental small-angle scattering data. The experimental technique for X-ray and neutron structure analysis involves small-angle scattering instrumentation, which is reviewed elsewhere (Glatter and Kratky, 1982; Schelten and ...

Novel concepts in neutron instrumentation
Physica B: Condensed Matter, 2000Abstract The most economical way to increase the neutron intensity at an instument is an optimization of all the components that are responsible for the extraction, moderation, transport, shaping and detection of the neutron beam. Because the principal interaction of neutrons with matter is of nuclear and magnetic origin, most components rely on ...

Multipurpose neutron-diffraction instrumentations
Nuclear Instruments and Methods, 1965Abstract An automatic multipurpose neutron diffractometer has been constructed for magnetic and crystallographic studies at temperatures 1.6°K to 1700°C with or without an external magnetic field of up to 18 kOe. Instrumental and functional characteristics of the following are given: a double-crystal diffractometer of normal-beam equatorial mode; a ...
