The U.S. Department of Energy (DOE) announced $35 million for research in computation and simulation techniques and tools to understand the nucleon structure, nuclear matter, and strong force via collaborations that enable effective use of DOE high performance computers.
Particle smashups have begun for Run 22 at the Relativistic Heavy Ion Collider (RHIC). RHIC, a 2.4-mile-circumference particle collider at the U.S. Department of Energy's Brookhaven National Laboratory, operates as a DOE Office of Science user facility, serving up data from particle collisions to nuclear physicists all around the world. On the menu this run: collisions between beams of polarized protons interspersed with tests of innovative accelerator techniques as the recently upgraded STAR detector tracks particles emerging from collisions at a wider range of angles than ever before.
Latifa Elouadrhiri has been presented with the 2021 Jesse W. Beams Research Award, which recognizes especially significant or meritorious research in physics that has earned the critical acclaim of peers from around the world. The award was established by the Southeastern Section of the American Physical Society (SESAPS) in 1973. Elouadrhiri is only the second woman to receive it.
This feature provides an overview of the science behind the discovery of superheavy elements and outlines ORNL's crucial role in supplying actinide target materials, highlighting some of the women scientists involved.
Globular clusters are collections of hundreds of thousands of stars that scientists believe evolved completely isolated from the rest of the universe. As such, they are perfect “stellar laboratories.” This research turned to the nuclear physics of an important type of reaction involving the sodium in these stars to help unlock what happened in the interiors of these stars to create the universe as we know it today.
Physicists have proposed a method to measure the speed of sound characterizing matter created in nuclear collisions. Heavy nuclei consist of hundreds of protons and neutrons, which themselves are composed of quarks and gluons. In heavy-ion collisions, the energy density of matter reaches very high levels, and the nucleons become a quark-gluon plasma. Experimental analyses can reveal properties of the quark-gluon plasma, helping scientists learn about the thermodynamics of dense nuclear matter.
The U.S. Department of Energy (DOE) announced $5.7 million for six projects that will implement artificial intelligence methods to accelerate scientific discovery in nuclear physics research.
A newly invented detector is allowing physicists at the U.S. Department of Energy’s Thomas Jefferson National Accelerator Facility to “see” neutrons like never before. Fresh insight from these devices has improved operation of the lab’s powerful electron accelerator, which is used in nuclear physics studies of the atom’s nucleus.
Neutrinos may be the key to finally solving a mystery of the origins of our matter-dominated universe, and preparations for two major, billion-dollar experiments are underway to reveal the particles’ secrets. Now, a team of nuclear physicists have turned to the humble electron to provide insight for how these experiments can better prepare to capture critical information. GENIE is simulation framework made of many models that each help physicists reproduce certain aspects of interactions between neutrinos and nuclei to help understand their experimental results. Since so little is known about neutrinos, it’s difficult to directly test GENIE to ensure it will produce both accurate and high-precision results from the new data that will be provided by future neutrino experiments. In this study, the team used an electron-scattering version of GENIE, dubbed e-GENIE, to test the same incoming energy reconstruction algorithms that neutrino researchers will use. Instead of using neutrinos, the
Jefferson Lab has appointed David J. Dean as its Deputy Director for Science. This key leadership position oversees the science and technology aspects of the laboratory’s mission. Dean will take on the responsibilities of this role in January 2022.
Jefferson Lab has appointed Cynthia Keppel as Jefferson Lab’s Associate Director for Experimental Nuclear Physics. In this role, Keppel will oversee more than 170 Jefferson Lab staff members.
A team of researchers used 3D particle simulations to model the acceleration of ions and electrons in a physical process called magnetic reconnection. The results could contribute to the understanding and forecasting of energetic particles released during magnetic reconnection, which could help protect space assets and advance space exploration.
On Oct. 25, the U.S. Department of Energy’s Thomas Jefferson National Accelerator Facility welcomed U.S. Secretary of Energy Jennifer Granholm and honored guests for a short tour of the lab and briefing on its research mission and plans for the future.
Sandia National Laboratories new 25,000-square-foot $42.5 million Emergency Operations Center complex is expected to be operational by spring 2023.
Iowa State physicists are contributing their expertise and sending thousands of pounds of Ames-manufactured hardware to the sPHENIX experiment at Brookhaven National Laboratory in New York. The experiment's particle detector is designed to explore the flowing, liquid-like, quark-gluon plasma.
Sandia National Laboratories launched three sounding rockets in succession on Wednesday to hasten development of 23 technologies for the nation’s hypersonic modernization priority, including the Navy’s Conventional Prompt Strike and the Army’s Long-Range Hypersonic Weapon programs.
Three Los Alamos National Laboratory scientists have been elected fellows by the American Physical Society (APS). The new APS fellows are Eric Brown, Takeyasu Ito and Nathan Moody.
Lawrence Livermore National Laboratory (LLNL) and Penn State scientists have demonstrated how a protein can be recovered and purified for radioactive metals like actinium that could be beneficial for both next-generation drugs used in cancer therapies and the detection of nuclear activities.
The American Physical Society has announced new fellows for 2021, and three Argonne scientists have been elected.
The American Physical Society (APS) has elected two scientists from the U.S. Department of Energy's (DOE) Brookhaven National Laboratory as 2021 APS fellows. The awardees are Kétévi Adiklè Assamagan and Swagato Mukherjee.
