Z-Pinch Plasma Neutron Sources 24 MAR 2006 54 pages
Authors:  A. L. Velikovich; R. W. Clark; J. Davis; Y. K. Chono; C. Deeney; C. A. Coverdale; C. Ruiz; G. Cooper; J. Franklin; L. I. Rudakov; SANDIA NATIONAL LABS ALBUQUERQUE NM
The full text of this report is available for sale.A deuterium gas-puff load imploded by a multi-MA current driver, from a large initial diameter could be a powerful source of fusion neutrons, a plasma neutron source. Unlike the beam-target neutrons produced in Z-pinch plasmas in the 1950s and deuterium-fiber experiments in the 1980s, the neutrons generated in deuterium gas-puffs, with current levels achieved in recent experiments on the SNL Z facility, could contain a substantial fraction of thermonuclear origin. ...


Plasma Radiation Source Development Program MAR 2006 188 pages
Authors:  Henry Sze; Phil Coleman; Bruce Failor; Jerry Levine; John Riordan; Yuanxu Song; Eduardo Waisman; MAXWELL PHYSICS INTERNATIONAL SAN LEANDRO CA
The full text of this report is available for sale.This report summarizes the results of a 3 year effort to develop long implosion time (>150 ns) z-pinch loads for use on the planned Decade Quad (DQ) pulsed power generator. Well diagnosed experiments demonstrated high quality, 200 ns implosions using argon gas puff loads. We show that solid fill and double shell mass distributions perform better than thin shells. The dual plenum, double shell load has unique diagnostic features that ...

The full text of this report is available for sale.This report describes the work of the Radiation Hydrodynamics Branch during FY 2004 in support of the DTRA's PRS and Sandia National Laboratories high energy density programs. It is a compilation of articles that were co- authored by Branch members. The titles are: (1) Controlling uniformity of gas- puff and wire array implosions with wire current-carrying structures, (2) Two- and three-wire loads for large current machines, (3) Enhanced energy coupling ...


Optical Tomography of the ZaP Flow Z-Pinch Plasma 2005 154 pages
Authors:  Adam M. Madson; WASHINGTON UNIV SEATTLE DEPT OF AERONAUTICS AND ASTRONAUTICS
The full text of this report is available for sale.The ZaP Flow Z-Pinch Experiment forms a Z-pinch with an embedded axial flow that exhibits stability for 500 - 2000 times the instabililty growth time for a static Z-pinch. Two linear photodiode arrays placed orthogonal to each other measure chord-integrated emissivity of the plasma. Deconvolving these data produce time resolved 1-D and 2-D emission profiles of the Z-pinch cross-section during the stable quiescent period. These unfiltered emission profiles show that ...


Advanced Radiation Theory Support Annual Report 2003, Final Report 19 APR 2004 103 pages
Authors:  J. Davis; J. W. Thornhill; J. L. Giuliani; J. P. Apruzese; Y. Chong; NAVAL RESEARCH LAB WASHINGTON DC RADIATION HYDRODYNAMICS BRANCH
The full text of this report is available for sale.This report describes the work of the Radiation Hydrodynamics Branch during FY 2003 in support of the DTRA PRS Program. Critical issues covered are (1) issues and directions for future research, (2) zero and one-dimensional modeling of DQ experiments, (3) enhanced energy coupling and x-ray emission in z-pinch implosions, (4) confinement and compression of magnetic flux by plasma shells, and (6) flashover and energy coupling in the DQ machine.


A Broad Band Radiation Source for Optical Absorption Spectroscopy Measurements in Single Shot Transient Media 20 JUL 2003 2 pages
Authors:  D. Hong; S. Guillot; G. Sandolache; J. M. Bauchire; E. Le Menn; ORLEANS UNIV (FRANCE)
The full text of this report is available for sale.In order to investigate the post-arc period and the hot gas regions surrounding the electrical arc in circuit breakers, a broad band radiation source has been developed to perform absorption spectroscopy measurements. The radiation spectrum has been characterized both temporally and spectrally in order to determine the best operating conditions to produce an intense and continuous radiation spectrum. Absorption tests have been performed on the hot gas region of a ...


High Power Gas-Discharge and Laser-Plasma Based EUV Sources 17 JUL 2002 7 pages
Authors:  Frank Flohrer; Kai Gaebel; Diethard Kloepfel; Peter Koehler; Imtiaz Ahmad; XTREME TECHNOLOGIES GMBH JENA (GERMANY)
The full text of this report is available for sale.In this paper we discuss new results from investigations on high power EUV sources for micro-lithography based on gas discharge produced plasmas and laser produced plasmas. The EUV development is performed at XTREME technologies OmbH, a joint venture of Lambda Physik AG, Gottingen, and Jenoptik LOS GmbH, Jena. For gas discharge EUV sources we report data based on Xenon filled Z-pinches. Prototypes of the EUV source achieve an EUV output ...


Magnetic Mode Analysis in the Zap Flow-Stabilized Z-Pinch Experiment 2002 134 pages
Authors:  Justin E. Bright; UNIV OF WASHINGTON SEATTLE AERONAUTICS AND ASTRONAUTICS
The full text of this report is available for sale.The Zap Flow-Stabilized Z-pinch experiment at the University of Washington studies the stabilizing effects of sheared flow on a Z-pinch. An internal eight-probe azimuthal array is used to measure the magnetic field. Fourier analysis of the magnetic field yields information on the structure of the plasma. The m=1 mode is related to the radial offset of the plasma, while the m=2 mode is related to the elongation of the plasma. ...
