    Superconducting Magnets Research for a Viable US Fusion Program Joseph V. Minervini1, Leslie Bromberg1, Peter J. Lee2, David C. Larbalestier2, Introduction Magnet systems are the ultimate enabling technology for magnetic confinement fusion devices. Powerful magnetic fields are required for confinement of the plasma, and, depending on the magnetic configuration, dc and/or pulsed magnetic fields are required for plasma initiation, ohmic heating, inductive current drive, plasma shaping, equilibrium and stability control. Almost all design concepts for power producing commercial fusion reactors rely on superconducting magnets for efficient and reliable production of these magnetic fields. Future superconducting magnets for fusion applications require improvements in materials, components, and configurations to significantly enhance the feasibility and practicality of fusion reactors as an energy source. A demonstration of large-scale demountable High Temperature Superconducting (HTS) magnets could revolutionize fusion energy development, dramatically reducing program cost and development time. Background OFES established and maintained a robust magnet technology development for several decades. Until the end of the ITER EDA (1998), the magnet technology R&D program was arguably the most successful of all enabling magnet technology programs. Most of the laboratories and universities performing superconducting magnet R&D had robust programs. A major milestone was the first (and only) successful operation of the massive superconducting magnet system for MFTF-B at LLNL in 1986. The high point was the successful completion (1999) and operation (2000) of the ITER CS Model Coil (CSMC). Since that time, funding for the development of superconducting magnets and almost all other enabling technologies has been on a steady decline, leading to the proposed magnet technology budget for FY 2013 of $765,000 or 0.19% of the total fusion budget.

    ERC Implementing Arrangements Call for Expression of Interest 2017 Project ID: Project Acronym: Evaluation Panel: 681178 G-EDIT LS1 Principal Investigator: Dr Mariusz Nowacki Host Institution: Universitat Bern - CH Mechanisms of RNA-guided genome editing in eukaryotes The goal of this project is to contribute to our understanding of RNA-mediated epigenetic mechanisms of genome regulation in eukaryotes. Ciliated protozoa offer a fantastic opportunity to investigate the complex process of trans-generational programming of chromosomal rearrangements, which is thought to serve as a form of immune defense against invasive DNA. Developmental processes in ciliates include extensive rearrangements of the germline DNA, including elimination of transposons and the precise excision of numerous single-copy elements derived from transposons. This process is considered to be maternally controlled because the maternal genome provides essential information in the form of RNA that determines the offspring's genome content and organization. This programmed DNA subtraction, the so-called ‘RNA scanning’ process, is mediated by trans-generational comparison between the germline and the maternal somatic genome. One of the most intriguing questions is how a complex population of small RNAs representing the entire germline genome can be compared to the entire rearranged maternal genome, resulting in the efficient selection of germline-specific RNAs, which are able to target DNA deletions in the developing genome. All this occurs in a very short time and involves a massively coordinated transport of all the components between three types of nuclei. This project focuses on characterizing the molecular machinery that can orchestrate the massive genome rearrangements in ciliates through nucleic acids and protein interactions.

Siemon Los Alamos National Laboratory J. Slough University of Washington M. Yamada Princeton Plasma Physics Laboratory I. Introduction The development of fusion energy represents one of the few long-term (multi-century time scale) options for providing the energy needs of modern (or postmodern) society. Progress to date, in parameters measuring the quality of confinement, for example, has been nothing short of stellar. While significant uncertainties in both physics and (particularly) technology remain, it is widely believed that a fusion reactor based on the tokamak could be developed within one or two decades. It is also widely held that such a reactor could not compete economically in the projected energy market. A more accurate statement of projected economic viability is that the uncertainty in achieving commercial success is sufficient that the large development costs required for such a program are not justified at this time. While technical progress has been spectacular, schedule estimates for achieving particular milestones along the path of fusion research and development have proven notoriously inaccurate. This inaccuracy reflects two facts.

    PLASMA CONFINEMENT IN A MAGNETIC DIPOLE* J. KESNER AND L. BROMBERG Plasma Science and Fusion Center MIT, Cambridge, MA 02139, USA D. GARNIER AND M. MAUEL Department of Applied Physics, Columbia University New York, NY 10027, USA Abstract A dipole fusion confinement device is stable to MHD interchange and ballooning modes when the pressure profile is sufficiently gentle. The plasma can be confined at high beta, is steady state and disruption free. Theory indicates that when the pressure gradient is sufficiently gentle to satisfy MHD requirements drift waves will also be stable. The dipole approach is particularly applicable for advanced fuels. A new experimental facility is presently being built to test the stability and transport properties of a dipole-confined plasma. 1. INTRODUCTION The dipole fusion concept was first proposed by Hasegawa [1, 2] who was motivated by observations of high β, energetic plasma within planetary magnetospheres. Active magneto- spheres, such as that surrounding Jupiter, can have plasma pressures exceeding the magnetic pressure, β > 1. A dipole fusion confinement device takes advantage of these properties by operating with plasma profiles that have sufficiently gentle gradients to be stable to interchange and ballooning modes at high beta. This stability derives from plasma compressibility. The dipole confinement concept is fundamentally different from other fusion concepts since the diamagnetic ω frequency, *, proportional to the radial gradient of plasma pressure, is small relative to the magnetic drift frequency, ωd, proportional to the radial gradient of the magnetic field. The ω ω ≤ condition */ d 2 characterizes a unique regime in magnetic plasma confinement. It corresponds to MHD stability and the possible elimination of drift wave instabilities [3].

  • Written Statement of Dr. Stephen O. Dean President, Fusion Power Associates to Meeting of DOE Fusion Energy Sciences Advisory Committee February 29, 2012
    Written Statement Of Dr. Stephen O. Dean President, Fusion Power Associates To Meeting of DOE Fusion Energy Sciences Advisory Committee February 29, 2012 Public Comment Session First, let me say that I endorse the recommendation just made by Dr. Earl Marmar of MIT that no irrevocable decisions be made relative to reductions in the fusion program, as proposed in the President’s FY 2013 budget submission to Congress, until a vetting of such reductions occurs within the U.S. fusion community. This should be done by FESAC, or otherwise, to seek community consensus relative to priorities identified previously by FESAC. Much of the discussion has been focused on the proposed termination of the Alcator C- Mod program at MIT. The proposed termination is of serious concern, since that program has made, and is making, important contributions to our understanding of tokamak physics and, furthermore, is important to the training of the next generation of fusion scientists. Termination of Alcator C-Mod would mean a “double whammy” for the MIT fusion program, since DOE terminated the other significant experimental facility there last year, the Levitated Dipole Experiment (LDX). Without these two facilities, MIT will lack the facilities to continue providing experience to students doing experimental fusion research. But the problem with the proposed reductions is much broader and more serious that just the role and future of the MIT program. Reductions in other areas, such as High Energy Density Laboratory Plasmas (HEDLP), theory, and systems studies will result not only in a loss of valuable talent and expertise throughout the U.S.

    Superconducting Magnets Research for a Viable US Fusion Program Joseph V. Minervini1, Leslie Bromberg1, Peter J. Lee2, David C.

Powerful magnetic fields are required for confinement of the plasma, and, depending on the magnetic configuration, dc and/or pulsed magnetic fields are required for plasma initiation, ohmic heating, inductive current drive, plasma shaping, equilibrium, and stability control.

Future superconducting magnets for fusion applications require improvements in materials and components to significantly enhance the feasibility and practicality of fusion reactors as an energy source. An integrated program of advanced magnet R&D should be focused on developing alternative and innovative approaches that would lead to radical advances to substantially improve and accelerate the path to fusion reactor. A new opportunity that could significantly change the economic and technical status of superconducting magnets is now viable, namely the use of so-called High Temperature Superconductors (HTS) that have now been used for demonstration of superconducting fields > 30T in small bore solenoid geometries. Recent studies performed at MIT indicate that HTS magnets that make use of demountable magnets is becoming a feasible option for future devices. This could have massive impact on fusion reactor performance and on the ability to maintain the machine, and increase reliability and availability. The state of the art in fusion superconducting magnet systems is ITER. The technology for ITER was developed in the 90’s, and although there are still some issues with the superconductor, the technology has been used successfully in model coils and in other smaller fusion experiments.
