Available in PDF, EPUB and Kindle. Book excerpt: An intense (4 x 107 s−1), low energy (approx. =1.0 eV), monoenergetic (.delta. E approx. = 75 MeV) beam of positrons has been built at the Brookhaven National Laboratory. This flux is more than 10 times greater than any existing beam from radioactive sources. Plans are underway to increase further the flux by more than an order of magnitude. The intense low energy positron beam is made by utilizing the High Flux Beam Reactor at Brookhaven to produce the isotope 64Cu with an activity of 40 curies of positrons. Source moderation techniques are utilized to produce the low energy positron beam from the high energy positrons emitted from 64Cu. 31 refs., 7 figs.

This book was released on 2012-12-06 with total page 688 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the lectures presented at the NATO Advanced study Institute "Fundamental Processes of Atomic Dynamics" held in Maratea. Italy from September 20th to October 2nd 1987. The institute and this volume were conceived as a natural complement to previous institutes held in Maratea (1982) and in Santa Flavia (1984. ) whose proceedings are to be found in NATO ASI Series B vol. 103 and 134 respectively. The subject matter of these institutes was the study of the funda mental processes occurring in the interactions of atoms with photons. electrons and heavy-ions. The aim has been to unify these processes in a coherent experimen tal and theoretical approach. The present volume brings this approach up to date and contains in addition. for contrast and variety. a description of similar dynamical processes in the study of clusters and surfaces. The institute was opened with a lecture by Joe Macek in which he summarised the current status of atomic collision research. propounded the philosophy of a unified approach to structure, fragmentation and collision and posed the outstanding questions in the field. This lecture forms the introduction to this volume. The subject matter was divided into experiment and theory with the lectures inter-linked so that the one could re-inforce the other. The whole of the theoretical part of the institute was organised by Ugo Fano as an on-going symposium.

Book Synopsis Positron Beams And Their Applications by : Paul G Coleman
Download or read book Positron Beams And Their Applications written by Paul G Coleman and published by World Scientific. This book was released on 2000-01-22 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a coherent and comprehensive overview of the generation and application of mono-energetic positron beams. It has been written by acknowledged experts, at a level accessible to graduate students working, or planning to work, with positron beams, and to scientists in other areas who want to know something about the field.The book begins with a brief historical introduction and an overview of how positron beams are generated and transported. A description of the fate of slow positrons in gaseous and condensed matter, with reference to many of the fundamental measurements made possible by the advent of positron beams, is followed by a discussion on applications in the study of solid surfaces, defect profiling in subsurface regions, interfaces and thin films, and the probing of bulk properties in novel ways. The book ends with a look at the future, considering the prospects for intense positron beams and their potential for further research.

Download or read book Intense Positron Beams and Possible Experiments written by and published by . This book was released on 1983 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In this paper, we survey some of the ideas that have been proposed regarding the production of intense beams of low energy positrons. Various facilities to produce beams of this type are already under design or construction and other methods beyond those in use have been previously discussed. Moreover, a variety of potential experiments utilizing intense positron beams have been suggested. It is to be hoped that this paper can serve as a useful summary of some of the current ideas, as well as a stimulation for new ideas to be forthcoming at the workshop. 31 references.
Book Synopsis A 0. 5 to 3. 0 MeV Monoenergetic Positron Beam by :
Download or read book A 0. 5 to 3. 0 MeV Monoenergetic Positron Beam written by and published by . This book was released on 1988 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: An adjustable, 0.5--3 MeV monoenergetic positron beam has been constructed at Brookhaven. Currently a 22Na source with a W(100) foil transmission moderator produces a 1.1 mm FWHN beam with an intensity of 3 x 105 e/sec at a target located downstream from the accelerator. The divergence of the beam is less than 0.1/degree/ at 2.2 MeV energy. A SOA gun with 2 lens transport system brings the beam to a focus at the entrance of an electrostatic 3 MeV Dynamitron accelerator. The post acceleration beam transport system comprises 3 focusing solenolds, 4 sets of steering magnets and a 90/degree/ double focusing bending magnet. The beam energy spread at the target is
Download or read book Intense Positron Beams written by and published by . This book was released on 1983 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Beams of monoenergetic positrons with energies of a few eV to many keV have been used in experiments in atomic physics, solid state physics and materials science. The production of positron beams from a new source, an electron linac, is described. Intense, pulsed beams of low-energy positrons have been produced by a high-energy beam from an electron linac. The production efficiency, moderator geometry, beam spot size and other positron beam parameters have been determined for electrons with energies from 60 to 120 MeV. Low-energy positron beams produced with a high-energy electron linac can be of much higher intensity than those beams currently derived from radioactive sources. These higher intensity beams will make possible positron experiments previously infeasible.
