Antibaryon Photoproduction using CLAS at Jefferson Lab

Antibaryon production has been investigated since the advent of nuclear physics, largely motivated by the potential for baryon-antibaryon bound states. Due to the recent availability of high statistics experiments there has been a renewed interest in how antibaryons are created in photoproduction. The g12 (E04-005) experiment conducted at Thomas Jefferson National Accelerator Facility used the CEBAF Large Acceptance Spectrometer to provide the world’s largest dataset for baryon-antibaryon photoproduction on a liquid hydrogen target. The focus of this work is to investigate the photoproduction mechanism of gp --> pp¯p through detailed differential cross section measurements from 3.95 to 5.45 GeV. These first time results as well as the resulting total cross section measurement are reported. In particular the energy dependence (s(Eg)) and the angular dependence (ds/d cos(qCM ¯ p )) have interesting features that have never been seen before. On the other hand, the mass distributions (ds/dM(pp) and ds/dM(p ¯ p) do not show evidence for previously reported narrow resonances. In addition, the first time total cross section mesurement of an antineutron in photoproduction using the reaction gp --> pp ¯np- is reported. The significance and implications of these results will be discussed as well.

Power Sector Resilience Planning: To Ensure Reliable, Secure, Safe and Affordable Electricity Supplies (Lab Translation)

Decision makers around the globe are exploring strategies to ensure the reliable, secure, safe, and affordable supply of electricity to power economic growth and achieve development goals. Vulnerabilities of the power sector to natural hazards (e.g., acts of nature, severe weather, and climate variabilities), technological hazards (e.g., accidents and system or structure failures), and threats or human-caused incidents (e.g., intentional cyber-attacks or acts of terror) can impede the provision of the energy services necessary to achieve these goals. Although decision makers cannot prevent an act of nature such as an earthquake, they can anticipate, prepare for, and adapt to potential vulnerabilities through planning. The purpose of power sector resilience planning is to identify vulnerabilities and devise strategies to mitigate them. This document reviews some of the hazards that power sectors face and how decision makers can plan to increase resilience.

Research Performance Progress Report - DOE Solar Program, Soft Costs, National Lab Projects: Promotion of PV Soft Cost Reductions in the Southeastern US

Beginning in 2014, the installed solar capacity in South Carolina (SC) grew from less than 20 megawatts to more than 300 megawatts today. Concurrently, the number of customer-sited, load-centered solar generation is expected to grow from less than 500 statewide to as many as 10,000 by 2021. This growth is the direct result of a landmark state policy initiative, Act 236, passed by the South Carolina General Assembly and signed into law by the Governor in June of 2014. Today, local policy makers in South Carolina are ill-equipped to handle the onslaught of solar permitting and zoning requests expected to come with such quick growth of an emerging market. Similarly, the state’s building inspectors, first responders, and tax assessors know little about photovoltaic (PV) technology and best practices. Finally, South Carolina’s workforce and workforce trainers continue to be underprepared to benefit from the tremendous opportunity created by the passage of Act 236. Each of these deficits in knowledge of and preparedness for solar PV translates into higher “soft costs” of installed solar PV in South Carolina.

Highlights of the 2016 Summer Laboratory Student Intern Program at Sandia National Labs [Slides]

Combined picosecond (10 -12 s) and femtosecond (10 -15 s) laser pulses can give sensitive, low-noise measurements of important quantities in reacting flows, such as species concentrations and temperature. Emmanuel’s work focused on the development of an instrument for tailoring the time profile of picosecond laser pulses for use in nonlinear optical spectroscopic methods created from broad bandwidth femtosecond pulses. In addition to constructing the device, Emmanuel produced a LabView-based automation code, building off skills he developed in a previous CCI internship at Sandia.

Measurement of High Coercitivity PrFeB Magnets at the Louis Neel Lab

Magnetization curves of newly developed high coercivity PrFeB magnets have been measured at various temperatures down to 40K. The measurement was carried out at the Lous Néel Laboratory in Grenoble, France using its 11T superconducting magnetometer. It has been shown that no significant gain in performance can be achieved below 77K where one can expect 16% gain in the remanence compared to that at a room temperature.

Interrelationship between Lab, Space, Astrophysical, Magnetic Fusion, and Inertial Fusion Plasma Experiments (Graduate support for DIII-D Frontier Science Experiments)

The project, to explore the use of the DIII-D facility to investigate questions of value to discovery plasma science and provide a deepened scientific understanding behind basic plasma processes that are outside of the fusion-energy-science research line, began in September 2016 when five discovery-plasma physicists were contacted by General Atomics to form a Frontier Science Experiments (FSE) panel for brainstorming and for implementing the FSE campaign at the DIII-D National Fusion Facility. After advertising the FSE opportunity at the annual plasma physics conference, the panel grew to include six others. By January 2017, the panel for reviewing and ranking proposals was established. Evaluation of FY2017 proposals took place in February 2017. Evaluation of FY2018 proposals took place in January 2018. This proposal began 15 August 2017 and funded two research assistantships for three students who interacted, gained expertise in experimental and computational physics, and shared responsibilities on the following projects within the DIII-D (non-fusion) Frontier Science Experiments (FSE) campaign: (1) "Impact of Magnetic Perturbations on Turbulence - Zonal Flow Interactions and Saturation", (2) "Nonlinear Processes during Toroidal Alfvén Mode-Mode Interaction", (3) "Self-Consistent Chaos in Magnetic Field Dynamics", (4) “Nonmodal Decomposition of Turbulence”, and (5) “Multi-harmonic EMIC Emission -- Species mix and distribution function dependence of instabilities near the ion-cyclotron frequency”. The outcome was a fraction of one doctoral dissertation and the entirety of one master of science thesis. The work took advantage of the unique capabilities of the DIII-D National Fusion Facility to serve as the first phase of the Frontier Science Experiment (FSE) campaign, an innovative concept aiming to advance fundamental understanding in 3 key general plasma science areas - particle acceleration and energetic particles in plasmas, turbulence and transport in plasmas, and nonlinear waves and processes – all at discovery’s cutting edge.

Watch former Lab Director and Manhattan Project Veteran Harold Agnew’s 1985 speech

From the first nuclear reactor to the weapon development to the bomb delivery in war, Harold Agnew was there. The only two atomic bombs to ever be used in combat – Little Boy, a uranium gun-type weapon, and Fat Man, a plutonium implosion weapon – were released above Japan 75 years ago on Aug. 6 and Aug. 9, respectively. World War II ended not long after. And, according to The New York Times, Agnew was the only person to witness the whole undertaking, from reactor to Hiroshima: Years earlier, on a frigid December day in 1942 in Chicago, a 21-year-old Agnew was one of a few dozen gathered to see atoms split in two. Not long after, Agnew came to Los Alamos as a graduate student to work on the development the atomic bomb. Then, on Aug. 6, 1945, Agnew was a part of the delivery of Little Boy; he flew as a scientific member on the mission to Hiroshima to film the mushroom cloud and measure the shockwave. It is the only existing footage of the Hiroshima bombing from the air; other footage was taken, but was most likely not handled properly and was unusable, according to Agnew.

A look back 75 years at Little Boy, the crew, the plane and the Lab’s first mission

Hours before the sun would rise over Tinian island on the morning of August 6, 1945, a B- 29 airplane was positioned above a specially built bomb-loading pit, as crews readied it with cargo unlike anything the world had ever known. Preparations on the tiny Pacific island—nearly 6,600 miles from Los Alamos and about 1,500 miles from its intended target in Japan—had begun months before on April 3. And months before that, pilot Paul Tibbets Jr. and his crew had practiced dropping dummy concrete bombs on targets in Utah. Even years before that, development of this cargo destined for Japan began in secrecy under the direction of a physicist and an Army general in the mountains of Northern New Mexico. It was all leading to one day that would help end years of bloodshed and change the world forever.

Strategies for seeking a job at a national lab [Slides]

Understanding the job market from the hiring side can help you develop better strategies for seeking a job. National laboratories represent a substantial source of jobs in the U.S. in engineering and science. High school, college, and graduate student internship positions are all available, but you can be more successful in finding one of these positions if you use a targeted search. Likewise, reaching out to individual researchers and/or knowing how to respond to job ads can increase your chances of getting an interview for a permanent job or positions, such as postdoc and postbac appointments, that can lead to permanent jobs. In my career as a research scientist at Los Alamos National Laboratory, I have hired people into all of these job categories, as well as served on many hiring committees for all levels of appointments. I will offer Polonius*-type advice for jobseekers and discuss the hiring process and how you can optimize your own job search.

Ghost particles and Project Poltergeist: Long-ago Lab physicists studied science that haunted them

A neutrino is a tiny, almost massless particle that travels at near light speeds. They were first formed in the early universe and are continually being produced in the nuclear reactions of stars, like the sun, and nuclear reactions on earth. The existence of these “ghost particles” was incredibly difficult to detect, but doing so has helped scientists better understand fundamental principles in physics. Los Alamos Manhattan Project scientist Frederick Reines, along with his colleague Clyde Cowan, is credited with the experimental discovery of the nearly massless elementary particle after his team definitively proved the neutrino’s existence in 1956. Reines received the Nobel Prize in Physics in 1995.
