Available in PDF, EPUB and Kindle. Book excerpt: Parameters of the plasma focus experimental assembly at Culham, England, a coaxial gun type first described by Mather, have been evaluated using advanced laser diagnostic techniques. The measurements have resulted in a more nearly complete appreciation of the formation, duration, and breakup of the dense pinch phase of the focus. (Modified author abstract).

This book was released on 1971 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: Characteristics of neutron production from a 16-27 kJ plasma focus device were systematically studied for device parameters of bank energy, gas pressure, gas impurities and anode geometry. Neutron yields of 10 to the 9th power - to -10 to the 10th power per discharge were obtained with deuterium. Comparison of neutron and hard x-ray production was made using photomultiplier-plastic scintillator detectors. The axial neutron distribution was determined using a paraffin-polyethelene collimator. A good time correlation between the hard x-rays and the neutrons was observed. The dependence of the axial neutron source distribution on pressure was obtained and related to the shape of the collapsing plasma boundary. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The Dense Plasma Focus (DPF) is a simple Z-pinch device with the ability of producing X-rays and neutrons. Neutron production from a DPF is susceptible to electrical parameters such as voltage and current, as well as mechanical parameters including electrode geometry and insulator sleeve length. Experiments that investigate three different anode geometries on a 4.6 kJ DPF device with a voltage of ~20 kV and a current of ~230kA were carried out. Two anodes with a hemispherical tip, one with and one without a hollow, were explored as well as an anode with a flat tip, hollo, and concentric slits. In order to analyze the pinches produced in these experiments, a neutron activation detector, X-ray PIN diodes, and a series of time-resolved Schlieren probing, were used. Hollow anodes create a higher neutron yield based on recent magnetohydrodynamics simulations that show the extension and dynamics of pinches in the hollow structure. Experimental evidence of extension of the pinch column is shown for the first time using the flat top hollow anode with slits. The maximum neutron yield obtained in these experiments was 1.97E ± 0.1x108 neutrons per pulse which was acquired using the hemispherical hollow anode while hard X-ray emission was observed with the hemispherical solid anode. Based on this analysis, one can conclude that anode with a hollow is optimal for neutron production while one without a hollow is prone to ablation and serves as an X-ray source.

This book was released on 1980 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report investigates the correlation between the neutron (and x-ray) emission intensity and the intensity of the particle beams generated in a plasma focus discharge in deuterium as an extension of our previous work on scaling laws of x-ray and neutron production. The structure of dense plasmoids which emit MeV ions has been recorded by ion imaging with pinhole camera and contact print techniques. The plasmoids are generated in the same region in which particle beams, neutron and x-ray emission reach a maximum of intensity. Sharply defined boundaries of the ion-beam source and of plasmoids have been obtained by ion track etching on plastic material CR-39.

Download or read book Neutron Generators for Analytical Purposes written by International Atomic Energy Agency and published by IAEA Radiation Technology Repo. This book was released on 2012 with total page 145 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication addresses recent developments in neutron generator (NG) technology. It presents information on compact instruments with high neutron yield to be used for neutron activation analysis (NAA) and prompt gamma neutron activation analysis in combination with high count rate spectrometers. Traditional NGs have been shown to be effective for applications including borehole logging, homeland security, nuclear medicine and the on-line analysis of aluminium, coal and cement. Pulsed fast thermal neutron analysis, as well as tagged and timed neutron analysis, are additional techniques which can be applied using NG. Furthermore, NG can effectively be used for elemental analysis and is also effective for analysis of hidden materials by neutron radiography. Useful guidelines for developing NG based research laboratories are also provided in this publication.
