Talking the Higgs Boson with Dr. Joseph Incandela: Third Lecture in the DOE Science Speaker Series (includes opening remarks from Dr. Bill Brinkman and introduction by Energy Secretary, Dr. Steven Chu)

In July of 2012, scientists leading two different research teams, working independently of each other, announced that they had almost certain proof of the long-sought Higgs boson. Though Cern did not call the discovery "official", many physicists conceded the evidence was now so compelling they had surely found the missing particle. The formal confirmation will come over the next few months of further investigation. The experiments are taking place at the Large Hadron Collider (LHC), and this third lecture in the DOE Science Speaker Series is given by one of those announcing scientists in July. He is Dr. Joseph Incandela, the current spokesperson for the Compact Muon Solenoid (CMS) Experiment at CERN. He was heavily involved in the search for the top quark at Fermi and is from the University of California, Santa Barbara. The title he gives his presentation is "Searching for the genetic code of our universe: Discovery at the LHC."

Spiral Development for Safeguards Instrumentation

Safeguards instrumentation is highly specialized, so a common approach in the US has been to develop initial prototypes for performance, operability and security within the US National Laboratories for the IAEA and then seek one or more commercial partners. Transfer of technology from US National Laboratories is a legal requirement for products that have the potential for mass production. Other important objectives include minimizing time to deployment and lifecycle cost, and optimizing product maintainability, sustainability and manufacturability. Unfortunately, the deployment of systems developed via this model has sometimes been seriously delayed or never adopted because of the difficulty of optimizing the significant parameters of the process between the public and private sectors. The authors suggest that forming an R&D partnership between a research laboratory and a commercial company much earlier in the process would provide significant advantages. The present US practice leads to unnecessary expenditures during the early R&D phase since many decisions are made based on research needs that are counterproductive for commercialization and manufacturability. If the ultimate goal of the project is to produce a reliable and cost effective commercial product, the commercial input is needed early and often. The new “model” of developing systems in a closer collaboration with the private sector, in a spiral “Commercialization by Design” approach, should also limit the long term financial mortgages that Member States frequently experience with respect to safeguards instrumentation development using the present process. As a concrete example, the potential for incorporating Wire Integrity Verification Technology into the iCobra Reader System is discussed.

Power Electronics Thermal Management R&D (Presentation)

This project will investigate and develop thermal-management strategies for wide bandgap (WBG)-based power electronics systems. Research will be carried out to deal with thermal aspects at the module- and system-level. Module-level research will focus on die- and substrate-integrated cooling strategies and heat-transfer enhancement technologies. System-level research will focus on thermal-management strategies for the entire power electronics system to enable smart packaging solutions. One challenge with WBG device-based power electronics is that although losses in the form of heat may be lower, the footprint of the components is also likely to be reduced to reduce cost, weight, and volume. Combined with higher operational temperatures, this creates higher heat fluxes which much be removed from a smaller footprint, requiring advanced cooling strategies.

NREL Partnership Survey - FY 2016 Results

The National Renewable Energy Laboratory (NREL) conducts an annual partnership satisfaction survey in which we ask our clients to rate NREL in a number of areas. As a national laboratory, the principal areas we focus on include value, timeliness, quality, price, and capabilities. This fact sheet shows the results of a survey with 300 customers responding to 11 questions using ratings that vary from 'strongly agree' to 'strongly disagree.' In FY 16, 100% of the scores improved or were equal to FY 15 numbers.

Optics & Materials Science & Technology (OMST) Organization at LLNL

The Optics and Materials Science & Technology (OMST) organization at Lawrence Livermore National Laboratory (LLNL) supplies optics, recycles optics, and performs the materials science and technology to advance optics and optical materials for high-power and high-energy lasers for a variety of missions. The organization is a core capability at LLNL. We have a strong partnership with many optical fabricators, universities and national laboratories to accomplish our goals. The organization has a long history of performing fundamental optical materials science, developing them into useful technologies, and transferring them into production both on-site and off-site. We are successfully continuing this same strategy today.

How I Learned to Stop Worrying and Love 3D Printing

The nuclear nonproliferation regime has many robust measures in place to prevent the acquisition of a nuclear weapon, a key pillar of which is denying or preventing the transfer of technology to specific actors. Additive manufacturing (AM) is a rapidly advancing, not fully understood technology that could dramatically alter the landscape of the safeguarded fuel cycle. However, many of the benefits of AM could also be used to circumvent or defeat current safeguard practices and controls. Because the AM capability is not fully understood, research and integration is necessary early in the technology development stages in order for nonproliferation to remain on the leading edge of discovery and not the tail end of technology deployment.

In-Vehicle Assessment of Human Exposure to Electromagnetic Fields from 25-kW Wireless Power Transfer System Based on Near-Field Analysis

Wireless power transfer (WPT) technology has the potential to be a convenient and reliable charging method for the light and heavy duty electric vehicles. However, the loose coupling between the two sides results in strong near-electromagnetic fields (EMFs) around the system, which may have the possibility to impact human safety if the standard limits are exceeded. Therefore, comprehensive tests are necessary to ensure the electromagnetic fields are with in safe limits. This paper presents a test methodology for the near-field from a 25-kW WPT system from Momentum Dynamics, which is installed in a heavy-duty electric shuttle at the National Renewable Energy Laboratory (NREL). The paper describes in detail the measuring device, test setup, and conditions.

Eastern Europe Research Reactor Initiative nuclear education and training courses - Current activities and future challenges

The Eastern Europe Research Reactor Initiative was established in January 2008 to enhance cooperation between the Research Reactors in Eastern Europe. It covers three areas of research reactor utilisation: irradiation of materials and fuel, radioisotope production, neutron beam experiments, education and training. In the field of education and training an EERRI training course was developed. The training programme has been elaborated with the purpose to assist IAEA Member States, which consider building a research reactor (RR) as a first step to develop nuclear competence and infrastructure in the Country. The major strength of the reactor is utilisation of three different research reactors and a lot of practical exercises. Due to high level of adaptability, the course can be tailored to specific needs of institutions with limited or no access to research reactors. (authors)
