Available in PDF, EPUB and Kindle. Book excerpt: We have examined the observed currents in the front foils of the JET Faraday cup lost alpha particle diagnostic KA-2. In particular, we have sought to understand the currents during Ohmic plasmas for which the ion flux at the detectors was initially assumed to be negligible. We have considered two sources of this current: plasma ions both deuterium and impurity in the vicinity of the detector including charge exchange neutrals and photoemission from scattered UV radiation. Based upon modeling and empirical observation, the latter source appears most likely and, moreover, seems to be applicable to the currents in the front foil during ELMy H-mode plasmas. A very thin gold or nickel foil attached to the present detector aperture is proposed as a solution to this problem, and realistic calculations of expected fluxes of lost energetic neutral beam ions during TF ripple experiments are presented as justification of this proposed solution.

Download or read book Initial Results from the Lost Alpha Diagnostics on Joint European Torus written by and published by . This book was released on 2007 with total page 624 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two devices have been installed in the Joint European Torus (JET) vacuum vessel near the plasma boundary to investigate the loss of energetic ions and fusion products in general and alpha particles in particular during the upcoming JET experiments. These devices are (i) a set of multichannel thin foil Faraday collectors, and (ii) a well collimated scintillator which is optically connected to a charge-coupled device. Initial results, including the radial energy and poloidal dependence of lost ions from hydrogen and deuterium plasmas during the 2005-06 JET restart campaign, will be presented.
Download or read book The Status of Alpha particle Diagnostics written by and published by . This book was released on 1992 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is a flurry of activity to complete alpha-particle diagnostics so that they can undergo some experimental testing in DT plasmas on JET or TFTR prior to implementation on ITER. Successful measurements of escaping charged fusion products have been made in DD plasmas, and the [alpha]-particle source can be well characterized by neutron profile measurement. These methods can be extrapolated to DT plasmas. Measurement of the confined [alpha]-particles requires a new technique. Collective Thomson scattering, methods involving charge-exchange interactions and nuclear reactions with impurities will be discussed. Some assessment is given of the capabilities of these techniques, bearing in mind the potential for their use in the physics phase of the ITER program.

This book was released on 2013-03-09 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: TO THE SECOND EDITION In the nine years since this book was first written, rapid progress has been made scientifically in nuclear fusion, space physics, and nonlinear plasma theory. At the same time, the energy shortage on the one hand and the exploration of Jupiter and Saturn on the other have increased the national awareness of the important applications of plasma physics to energy production and to the understanding of our space environment. In magnetic confinement fusion, this period has seen the attainment 13 of a Lawson number nTE of 2 x 10 cm -3 sec in the Alcator tokamaks at MIT; neutral-beam heating of the PL T tokamak at Princeton to KTi = 6. 5 keV; increase of average ß to 3%-5% in tokamaks at Oak Ridge and General Atomic; and the stabilization of mirror-confined plasmas at Livermore, together with injection of ion current to near field-reversal conditions in the 2XIIß device. Invention of the tandem mirror has given magnetic confinement a new and exciting dimension. New ideas have emerged, such as the compact torus, surface-field devices, and the EßT mirror-torus hybrid, and some old ideas, such as the stellarator and the reversed-field pinch, have been revived. Radiofrequency heat ing has become a new star with its promise of dc current drive. Perhaps most importantly, great progress has been made in the understanding of the MHD behavior of toroidal plasmas: tearing modes, magnetic Vll Vlll islands, and disruptions.

This book was released on 2012-12-06 with total page 564 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Fourth International Conference on Ion Implantation: Equipment and Tech niques was held at the Convention Center in Berchtesgaden, Bavaria, Germany, from September 13 to 17, 1982. It was attended by more than 200 participants from over 20 different countries. Severa1 series of conferences have dealt with the app1ication of ion implantation to semiconductors and other materials (Thousand Oaks, 1970; Garmisch-Partenkirchen, 1971; Osaka, 1974; Warwick, 1975; Bou1der, 1975; Budapest, 1978; and Albany, 1980). Another series of conferences has been devoted to implantation equipment and techniques (S- ford, 1977; Trento, 1978; and Kingston, 1980). This conference was the fourth in the 1atter series. Twe1ve invited papers and 55 contributed papers covered the areas of ion implantation equipment, measuring techniques, and app1ica tions of implantation to metals and semiconductors. A schoo1 on ion implantation was held in connection with the conference, and the 1ectures presented at this schoo1 were pub1ished as Vo1. 10 of the Springer Series in E1ectrophysics under the tit1e Ion Implantation Techniques (edited by H. Rysse1 and H. G1awischnig). During the conference, space was also provided for presentations and demonstrations by manufacturers of ion implantation equipment. Once again, this conference provided a forum for free discussion among implantation specia1ists in industry as we11 as research institutions. Espe cially effective in stimulating a free exchange of information was the daily get-together over free beer at the "Bier Adam". Many people contributed to the success of this conference.

Download or read book Direct Energy Conversion written by Andrea M. Mitofsky and published by Createspace Independent Publishing Platform. This book was released on 2018-08-25 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: Direct Energy Conversion discusses both the physics behind energy conversion processes and a wide variety of energy conversion devices. A direct energy conversion process converts one form of energy to another through a single process. The first half of this book surveys multiple devices that convert to or from electricity including piezoelectric devices, antennas, solar cells, light emitting diodes, lasers, thermoelectric devices, and batteries. In these chapters, physical effects are discussed, terminology used by engineers in the discipline is introduced, and insights into material selection is studied. The second part of this book puts concepts of energy conversion in a more abstract framework. These chapters introduce the idea of calculus of variations and illuminate relationships between energy conversion processes.This peer-reviewed book is used for a junior level electrical engineering class at Trine University. However, it is intended not just for electrical engineers. Direct energy conversion is a fascinating topic because it does not fit neatly into a single discipline. This book also should be of interest to physicists, chemists, mechanical engineers, and other researchers interested in an introduction to the energy conversion devices studied by scientists and engineers in other disciplines.
