Program Management The Program Manager, Jill Dahlburg, is responsible for overall direction of the GA/Schafer inertial confinement fusion target component fabrication and technology development support activity, including schedules, budgets, customer relations, and the oversight of the various Centers within the Division of Inertial Fusion Technology. Jill, who received her Ph.D. in theoretical plasma physics from the College of William and Mary in May, 1985, is recognized as an authority on: high performance computing algorithms and techniques, among them pseudo-spectral, finite difference, and Boolean logic methods; simulation and advanced visualization capabilities; fluid dynamics, which includes low speed Navier-Stokes flows and also high temperature gas dynamics with equation of state and radiation transport effects, and magnetohydrodynam- ics; and, experimental data analysis, interpretation, and integration with theory from a range of detectors, sensors and diagnostic tools. Upon completion of her doctoral dissertation under the direction of Dr. David C. Montgomery, now at Dartmouth College, Dr. Dahlburg joined the civil service research staff at the Naval Research Laboratory [NRL] in June, 1985 as a computational physicist in the Laboratory for Computational Physics and Fluid Dynamics. As a member of the NRL Nike KrF Laser Program from its inception, and Head of the Laser Plasma Hydrodynamics Section for that Program, Dr. Dahlburg supervised and contributed technically to the NRL Nike effort in laser direct drive ignition and high gain pellet designs, and to the design and modeling of laboratory laser matter interaction experiments, with emphasis on the understanding of the Raleigh Taylor instability, implosion and coronal hydrodynamics, and laser beam imprinting. In particular, she spearheaded the development of RAD3D, the first three-dimensional multi- group radiation transport hydro-code appropriate for laser-plasma modeling. RAD3D has remained a premier simulation code in that field for more than a decade. In 2000, Dr. Dahlburg joined the Tactical Electronic Warfare Division [TEWD] of NRL, as Head of the Distributed Sensor Technology Office. From that Office, reporting to Dr. John A. Montgomery of TEWD, she was Co-PI on the ONR/MCWL-sponsored SECNAV Small UAV initiative, Dragon Eye (which presently numbers among the Popular Science Top 100 Best of What’s New 2001 [Popular Science (December 2001)]), and PI for the NRL Micro Air Vehicle and Non-Conventional Aerodynamics Programs. Dr. Dahlburg’s technical collaborations have included scientists in both the national and international physics and engineering communities. General Atomics Report GA–A23852 4–3 FY01 ICF Annual Report Project Staff Dr. Dahlburg has served on numerous review and other committees for the Department of Energy, the National Academy of Sciences/National Research Council, the National Science Foundation, and the American Physical Society [APS], among them being named to the USDOE Fusion Energy Advisory Committee in 1998, to the USDOE Advanced Scientific Computing Advisory Committee in 2000, and to the LLNL National Security Advisory Committee in 2001. Her professional honors include five NRL Alan Berman Research Publication Awards, and being named APS Centennial Speaker (1998-99) and APS/DPP Distinguished Lecturer (1999-00). Her clearances include DoD TS and USDOE Q. Jill Dahlburg is a Fellow of the American Physical Society. 4–4 General Atomics Report GA–A23852 Project Staff FY01 ICF Annual Report 4.3.2. Center for Advanced Technology and Cryogenics Excellence The Center for Advanced Technology and Cryogenics Excellence focuses on the design, assembly, and testing of cryogenic target systems for ICF. Working as a team with UR/LLE, LANL, NRL, and LLNL we designed and built several cryogenic systems. A significant achievement for the center so far has been the design and testing of the Omega Cryogenic Target System with the significant participation of UR/LLE. This system fills, transports, and inserts cryogenic direct drive targets into the Omega target chamber in Rochester. Operational since late 2000, it is now routinely used to fill cryogenic direct drive targets. This year, we completed fabrication of the Deuterium Test System, the first apparatus available for conducting layering experiments on full-scale NIF indirect drive ignition targets, a crucial step in the ignition goal of Stockpile Stewardship. It will have the capability to fill targets by permeation to a pressure high enough that a full thickness fuel layer is generated upon cooling the target.We are an integral part of the design team for the NIF Cryogenic Target System, assigned to the lead the development of the Target Cryostats subsystem and the Layering subsystem, and provide general design support as requested on other systems and subsystems. Also in support of NIF, we are working with LANL to develop and build the NIF Beryllium Capsule Deuterium-Tritium Fill System, a system designed to fill hollow beryllium capsules with high-pressure DT gas by bonding two machined hemispherical shells together in a high temperature, high pressure, DT environment. The Center for Advanced Technology and Cryogenics Excellence is also the center for developing innovations in target fabrication with the emphasis on mass production. This includes (under another DOE contract) developing techniques to substantially decrease the cost of an ICF target from approximately $2.5K per target today to 25¢ per target for future IFE plants. The Center for Advanced Technology and Cryogenics Excellence supports the current ICF program in cryogenic engineering and is preparing for future programs by developing mass production techniques for target fabrication. Gottfried Besenbruch (Ph.D. Inorganic Chemistry, Justus Liebig University) is Associate Director of the Division of Inertial Fusion Technology and head of the Center for Advanced Technology and Cryogenics Excellence. Dr. Besenbruch has 35 years of experience in research, the development of technologies, and the design and construction of process plants. In his first 20 years at GA, he worked in the nuclear field, first as a scientist and later as a program manager.

  • The Effect of Surface Processing Methods on the Laser Induced Damage Threshold of Fused Silica
    The Effect of Surface Processing Methods on the Laser Induced Damage Threshold of Fused Silica by Weiran Duan A thesis submitted in partial fulfilment for the requirements for the degree of PhD at the University of Central Lancashire October 2014 2 To my family i Declaration I declare that while registered as a candidate for the research degree, I have not been a registered candidate or enrolled student for another award of the University or other academic or professional institution. I declare that no material contained in the thesis has been used in any other submission for an academic award and is solely my own work. Weiran Duan ii Abstract High peak power laser systems, such as National Ignition Facility (NIF), Laser Mega Joule (LMJ), and High Power laser Energy Research facility (HiPER), include a large amount of optics. Fused silica glass is one of the most common optical materials which is used in these high peak power laser systems owing to its excellent optical properties, especially for the 355nm ultraviolet laser. However, it is generally found that fused silica optics damage under irradiation with a high peak power laser beam, and the laser induced damage (LID) becomes the limit to increasing the laser power. Theoretically, the laser induced damage threshold (LIDT) of fused silica substrates is high, while it drops significantly due to the poor surface quality created in the manufacturing process. This project aims to find a series of fused silica optical surface processing techniques which are able to improve the surface quality and increase its LIDT when irradiated using high peak power lasers.

Frenje1 1Massachusetts Institute of Technology, Cambridge, MA 02139, USA Email: [email protected] The field of nuclear diagnostics for Inertial Confinement Fusion (ICF) is broadly reviewed from its beginning in the seventies to present day. During this time, the sophistication of the ICF facilities and the suite of nuclear diagnostics have substantially evolved, generally a consequence of the efforts and experience gained on previous facilities. As the fusion yields have increased several orders of magnitude during these years, the quality of the nuclear-fusion-product measurements has improved significantly, facilitating an increased level of understanding about the physics governing the nuclear phase of an ICF implosion. The field of ICF has now entered an era where the fusion yields are high enough for nuclear measurements to provide spatial, temporal and spectral information, which have proven indispensable to understanding the performance of an ICF implosion. At the same time, the requirements on the nuclear diagnostics have also become more stringent.

    MTF Proof-of-Principle Proposal App. A. Why MTF offers a low-cost development path. APPENDIX A Why Magnetized Target Fusion Offers A Low-Cost Development Path for Fusion Energy Richard E. Siemon Irvin R. Lindemuth Kurt F. Schoenberg Los Alamos National Laboratory Los Alamos, New Mexico Accepted by Comments on Plasma Physics and Controlled Fusion, December, 1997 1 MTF Proof-of-Principle Proposal App. A. Why MTF offers a low-cost development path. I. Introduction Reasonably priced energy supplies have become an expectation of the developed world and a necessary ingredient for development of Third World countries. The problem of providing large supplies of low-cost energy is a long-term, complex one that requires sustained R&D efforts, in spite of the shadow cast on long-term R&D by the federal deficit problem. The role of fusion energy as a power source was thoroughly reviewed and strongly endorsed in 1995 by the President’s Committee of Advisors on Science and Technology Fusion Review Panel chaired by John Holdren. He argued [Holdren 95]: The options available for meeting the world’s demand for energy in 2050 and beyond are those already in use – fossil fuels, biomass energy, nuclear fission, hydropower, geothermal energy, wind energy, and solar energy – plus, potentially, nuclear fusion. In these circumstances, it should be obvious that there is great merit in the pursuit of diversity in energy options for the next century. There are not so many possibilities altogether. The greater the number of these that can be brought to the point of commercialization, the greater will be the chance that overall energy needs can be met without encountering excessive costs from or unmanageable burdens upon any one source.
