Mike Dunne, Lawrence Livermore National Lab. (United States)
Abstract:: The National Ignition Facility (NIF) in California is the world’s largest and most energetic laser system. The NIF’s 192 beams recently exceeded their design specification to deliver 1.8-megajoule, 500-terawatt ultraviolet laser light in highly reproducible and precisely controlled conditions. This represents over 60 times more energy than any previous laser system, and has been designed to generate (in miniature) conditions that match or exceed those found at the center of the Sun. The ability to create temperatures of more than 100 million degrees and pressures more than 100 billion times Earth’s atmospheric pressure is used to drive the “fusion” of hydrogen into helium, releasing copious amounts of energy. The NIF is designed to compress fusion targets to the conditions required for “ignition”, liberating more energy than is required to initiate the fusion reaction (i.e., net production of energy). When achieved, this will mark the culmination of over 50 years of effort across the world. This talk will discuss the current status of the campaign to achieve ignition, presenting the most recent experimental results, and a look ahead to how this approach could be adopted to generate gigawatt levels of electrical power from a laser-driven source of fusion neutrons based on these demonstration experiments. Such a source is attractive because it will be inherently safe, generate no greenhouse gases or other environmental pollutants, provide security of fuel supply with fuel that will last for millennia, generate large-scale baseload power, be able to make use of the existing grid, have no need for geological waste disposal (unlike nuclear power or carbon sequestration), and will not require enrichment or reprocessing of nuclear material that could present a proliferation risk.
This work performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344.
Biography: Mike Dunne joined Lawrence Livermore National Laboratory in 2010 as Director for Laser Fusion Energy, charged with developing a revolutionary source of safe, secure, carbon-free baseload electricity. Mike’s role is to ensure full advantage is taken of the US National Ignition Facility (NIF), a $3.5 billion investment designed to demonstrate the proof of principle of laser fusion. NIF works by directing the world’s largest laser system to “ignite” a small mass of fuel to release copious amounts of energy. The process marks the culmination of over 50 years of research. Laser fusion energy has been pursued throughout this time because it is inherently safe, releases no greenhouse gases, has no long-lived waste and is based on widely available sources of fuel that will last for millennia. Previously, Mike was the International Project Leader for the European laser fusion project ‘HiPER’ (www.hiper-laser.org). He created a consortium of 26 institutions across 10 countries to develop one of the few Giga-Euro scale facility opportunities accepted onto the “European roadmap” of future research infrastructures (ESFRI), as well as onto the UK Large Facilities Roadmap. Mike held the post of Director of the United Kingdom’s Central Laser Facility (CLF) for five years, based at the Rutherford Appleton Laboratory. This is home to the world's most intense laser facilities, with science programmes ranging from biomedical research, to the study of astrophysics in the laboratory, and the development of a new generation of miniaturized particle accelerators.
He obtained his doctorate in laser fusion and laboratory astrophysics research from Imperial College, London, where he is now a visiting Professor. He is a Fellow of the Royal Society for the encouragement of Arts, Manufacturers and Commerce (FRSA), and a member of the American Association for the Advancement of Science, American Physical Society, European Physical Society, Institute of Physics, and the International Society for Optical Engineering.

6:25 to 7:00 pm: The Europa Clipper Mission Concept: Exploring a Potentially Habitable World
Robert T. Pappalardo, Jet Propulsion Lab., California Institute of Technology (United States)
Abstract: Galileo spacecraft data suggest that an ocean likely exists beneath the icy surface of Jupiter’s moon Europa and that the “ingredients” necessary for life (liquid water, chemistry, and energy) could exist there today. A NASA-appointed Science Definition Team (SDT), working closely with a technical team from the Jet Propulsion Laboratory (JPL) and the Applied Physics Laboratory (APL), recently considered options for a future strategic mission to Europa, with the stated science goal: Explore Europa to investigate its habitability. The favored architecture consists of a spacecraft in Jupiter orbit making many close flybys of Europa, concentrating on remote sensing of the moon. The mission would also include the capability to perform reconnaissance for a future lander, with the Reconnaissance goal: Characterize scientifically compelling sites to prepare for a future landed mission to Europa. Innovative mission design would use gravitational perturbations of the spacecraft trajectory to permit flybys at a wide variety of latitudes and longitudes, enabling globally distributed regional coverage of Europa’s surface, with nominally 45 close flybys at altitudes of 25 – 100 km. I will present the science and reconnaissance goals and objectives, a mission design overview, and the notional spacecraft for this concept known as the Europa Clipper.

9:15 to 10:00 am: Non-Covalent Interactions of Carbon Nanotubes in Polymer Composites
Eva M. Campo, Bangor Univ. (United Kingdom) and Univ. of Texas at San Antonio (United States)
Abstract: Despite much effort to control dispersion, alignment, and overall processing of Carbon Nanotubes, both their surface chemistry and distribution in polymer matrices remain an active topic of research. Growth and processing can yield local defects along the graphitic structure to become effective latching sites conducive to polymeric interaction; a prelude to dispersion. With all, the possibility of controlled surface chemistry paves the way of CNTs towards supramolecular chemistry. In this scheme, π-π and CH-π interactions play an important role in time-evolved bonding dynamics; which in turn, is exhorted by both chemistry and processing. We will engage in an exploration that provides insights into bonding in nanocomposites, offering invaluable information towards the synthesis-structure-property paradigm.

Coffee Break 10:00 to 10:30 am
10:30 to 11:15 am: Nanoscale Silicon as an Optical Material
Philippe M. Fauchet, Vanderbilt Univ. (United States)
Abstract: As the material at the core of all microelectronic devices, silicon has fueled most technological revolutions in the 20th century. It is abundant and, among inorganic materials, inexpensive. Due to extremely large industrial investments over the past decades, it was tamed like no other material before. However, with the possible exception of the photovoltaic industry, silicon has until recently been used by a single industry. The situation started changing over 20 years ago when advances in the manufacture of nanometer-size objects (e.g., quantum dots, wires, sheets) and devices with deep submicron features (e.g., photonic crystals) allowed researchers to manipulate the properties of bulk silicon and to exploit the unusual optical properties of nanoscale silicon structures. In this presentation, the history, including the most recent developments, of nanoscale silicon as an optical material will be reviewed with a special emphasis on active and biosensing structures.

2:25 to 2:50 pm: The Renaissance of CdTe-based Photovoltaics
William H. Huber, GE Global Research (United States)
Abstract: Over the past several years, CdTe-based photovoltaics have undergone a revolution. CdTe is a mature PV technology, spanning more than 55 years. Steady advancements in CdTe module manufacturing, coupled with CdTe’s inherent manufacturing simplicity, have driven down the cost of commercial CdTe modules to under $0.55/W at present. Until recently however, CdTe module efficiencies have lagged behind competing technologies. For a decade, CdTe record efficiencies remained dormant, far behind poly Si as well as the competing thin film PV technology, CuInxGa1-xSe2 (CIGS). Over the past several years, CdTe record cell efficiencies have dramatically increased and are nearly at parity with poly Si and CIGS. Given the recent trajectory, CdTe is poised to become the most efficient polycrystalline PV technology in the very near future. This talk will highlight the advantages of CdTe for PV, key advancements in the field and opportunities for further improvements.

3:45 to 4:10 pm: Hot Carrier Solar Cell Absorbers: Materials, Mechanisms and Nanostructures
Gavin Conibeer, Australian Ctr. for Advanced Photovoltaics, Univ. of New South Wales (Australia)
Abstract: The Hot Carrier solar cell is a Third Generation device that aims to tackle the carrier thermalisation loss after absorption of above band-gap photons. It is theoretically capable of efficiencies very close to the maximum thermodynamic limit. It relies on slowing the rate of carrier cooling in the absorber from ps to ns. This challenge can be addressed through nanostructures and modulation of phonon dispersions. The mechanisms of carrier cooling are discussed and methods to interrupt this process investigated to give a list of properties required of an absorber material. Quantum well or nano-well structures and large mass difference compounds with phonon band gaps are discussed in the context of enhancing phonon bottleneck and hence slowing carrier cooling. Materials for these structures are discussed and potential combined structures to maximize phonon bottleneck and slow carrier cooling are suggested.

These approaches are deeply connected; and in this talk, I will present a framework for understanding many common underpinnings of these ideas. This has led us to new insights and algorithms, yielding both deeper theoretical analysis, and state of the art results in practice.

Harrison H. Barrett, College of Optical Sciences, The Univ. of Arizona (United States); co-author: Kyle J. Myers, Ctr. for Devices and Radiological Health, U.S. Food and Drug Administration (United States)
Abstract: A fundamental way of describing a quantum-limited imaging system is in terms of a Poisson random process in spatial, angular and wavelength variables. The mean of this random process is the spectral radiance. The principle of conservation of radiance then allows a full characterization of the noise in the image (conditional on viewing a specified object). Radiance can be defined in terms of geometrical optics, physical optics, or quantum optics as well as for x-rays or gamma-rays, so a unified treatment of noise in imaging can be developed. Combined with well-established theories for task-based assessment of image quality, these concepts allow a rigorous definition of the information content of a photon.

5:25 to 6:05 pm: Optical Design for Consumer Products
Anurag Gupta, Google (United States)
Abstract: Engineers often focus the design parameters to meet certain well defined targets. Such approach assumes that the specifications they have are largely non-negotiable which is not always true and can result in sub optimal solutions or expensive multiple design iterations. A broader, product engineering focused, approach is needed to foster the most leveraged design. Optical engineering is somewhat unique considering a fragmented manufacturing base and limited understanding of optics in an engineering context in most teams and as a result, optics in a product is more vulnerable to changes. Understanding the product complexities that may impact the optical design can be quite useful.
Biography: Anurag Gupta is currently Nest sensor optics lead at Google at Mountain View. Earlier, he headed the optical engineering group for Google Glass. He received his PhD. from the Univ. of Arizona in Tucson and has since worked on more than fifty optics related projects in diverse fields.

Materials and Devices for Bioresorbable Electronics
John A. Rogers, Univ. of Illinois at Urbana-Champaign (United States)
Abstract: A remarkable feature of the modern integrated circuit is its ability to operate in a stable fashion, with almost perfect reliability. Recently developed classes of electronic materials create an opportunity to engineer the opposite outcome, in the form of devices that dissolve completely in water, with harmless end products. The enabled applications range from ‘green’ consumer electronics to bio-resorbable medical implants—none of which would be possible with technologies that exist today. This talk summarizes recent work on this physically ‘transient’ type of electronics, from basic advances in materials chemistry, to fundamental studies of dissolution reactions, to engineering development of complete sets of device components, sensors, and integrated systems. An ‘electroceutical’ bacteriocide designed for treatment of surgical site infections provides an application example.

Charge and Spin Transport Physics of Organic Semiconductors
Henning Sirringhaus, Cavendish Lab., Univ. of Cambridge (United Kingdom)
Abstract: Over recent years there has been tremendous progress in discovering new organic semiconductors that provide high charge carrier mobilities for both n-type and p-type device operation, good operational stability and other functionalities such as efficient electroluminescene, sensing or memory functions. These materials allow addressing an increasingly broad range of flexible and printed electronic applications based on controlled manufacturing of flexible plastic substrates by a combination of solution processing and direct printing. One of the sources of improvement in performance has been the versatility of organic chemistry to provide a broad range of new molecular structures and the ability to assemble these molecules into ordered structure with minimum degree of disorder. We will review recent insights into the device and charge transport physics of solution-processible small molecule as well as conjugated polymer organic semiconductors, with a particular focus on the microscopic processes that limit the field-effect mobility in these systems. We are also interested in understanding the spin transport physics of these materials and the relationship between molecular structure, microstructure and spin diffusion. Organic semiconductors may enable realisation of long spin relaxation times and long spin diffusion lengths due to the weak spin-orbit coupling in these carbon-based materials. We will present recent measurements of spin-transport in different molecular and polymeric semiconductors.
