QSA is breaking new ground in particle physics and promoting interdisciplinary teamwork to address critical scientific challenges.
Researchers at the Facility for Rare Isotope Beams reached a new milestone in isotope studies, accelerating a high-power beam of uranium ions to a record 10.4 kilowatts of continuous beam power to a target. The beam enabled scientists to produce and identify three new isotopes, gallium-88, arsenic-93, and selenium-96.
New experimental results suggest that sprinkling boron into a tokamak could shield the wall of the fusion vessel and prevent atoms from the wall from getting into the plasma. A new computer modeling framework shows the boron powder may only need to be sprinkled from one location. The experimental results and computer modeling framework will be presented this week at the 66th Annual Meeting of the American Physical Society Division of Plasma Physics in Atlanta.
New method for cathode preparation prevents the particle cracking that caused performance decline with cycling of sodium-ion batteries, which offer a cheaper, more abundant alternative to lithium-ion batteries.
A team from the University of Houston found that, when they reduced estimates of atmospheric friction of storms, their predictions on PSC’s Bridges-2 improved markedly over standard storm predictions. This advancement promises better planning to lessen the effects of storms on people and possibly aid emergency storm responses.
Over the summer, crews began the Alpine storage system, shredding over 40,000 hard drives with the help of ShredPro Secure, a local East Tennessee business. This partnership not only reduced costs and sped up the process but also established a more efficient and secure method for decommissioning large-scale computing systems in the future.
A new toolkit helps researchers build optimal superconducting radiofrequency (SRF) cavities that form the backbone of advanced particle accelerators. The cavities’ cleanliness, shape, and roughness of their inner surfaces contribute to their efficiency. In tests of the toolkit, scientists found that smoother cavities function more efficiently.
Deep inside what we perceive as solid matter, the landscape is anything but stationary. The interior of the building blocks of the atom’s nucleus — particles called hadrons that most of us would recognize as protons and neutrons — are made up of a seething mixture of interacting quarks and gluons, known collectively as partons. The HadStruc collaboration has now come together to map out these partons and disentangle how they interact to form hadrons. Their latest findings were recently published in the Journal of High Energy Physics.
As high-tech companies ramp up construction of massive data centers to meet the business boom in artificial intelligence, one component is becoming an increasingly rare commodity: electricity. With decades of experience in making HPC more energy efficient, the OLCF may serve as a resource for best “bang for the buck” practices in a suddenly burgeoning industry.
The 12th annual Argonne Training Program on Extreme-Scale Computing (ATPESC) offers intensive two-week training for next-generation scientists, computer experts, data analysts and others aiming to infuse their computing research with new vibrancy.
Researchers have developed FerroX, a new open-source, 3D simulation framework that could advance record-breaking energy efficiency in microelectronics by unveiling the microscopic origins of a physical phenomenon called negative capacitance in ferroelectric thin films.
The Department of Energy’s (DOE) Office of Science today announced a new research and development opportunity led by Oak Ridge National Laboratory (ORNL) to advance technologies and drive new capabilities for future supercomputers.
A team led by scientists at ORNL identified and demonstrated a method to process a plant-based material called nanocellulose that reduced energy needs by a whopping 21%, using simulations on the lab’s supercomputers and follow-on analysis.

Novel research developments as a result of multi-institution collaboration at the Quantum Systems Accelerator
Measuring computer chips to identify defects during manufacturing is crucial to improve production yield. Scientists from Delft and Utrecht investigated a novel imaging technique using EUV light—a high-energy short-wavelength radiation—to examine the 3D nanoscale structures on the chips. This technique eliminates the need to use any imaging system containing expensive EUV reflective mirrors in the measurement tool. Instead, images are reconstructed computationally from acquired diffraction data, resulting in a significant cost reduction.
$4.9 million from the NSF has funded an upgrade to PSC’s flagship Bridges-2 supercomputer. The grant has allowed the center to add late-model powerful NVIDIA H100 GPUs to the system, further enhancing its ability to support research in and requiring artificial intelligence, particularly in the context of massive data and high-performance computing.
Four of the nation’s top scientists have each been awarded $1 million in direct funding via the Department of Energy (DOE) Office of Science Distinguished Scientist Fellows program.
Extreme-scale science recognizes that disruptive technology changes are occurring across science applications, algorithms, computer architectures, and ecosystems. Emerging trends in this technology span key areas including high-end computing, massive datasets, visualization, and artificial intelligence on increasingly heterogeneous computer architectures.
A third-generation Anton supercomputer, developed by D. E. Shaw Research, will soon arrive at the Pittsburgh Supercomputing Center. A $3.15-million, five-year award from the National Institutes of Health will fund the system's operations, making it available without cost for non-commercial use by biomedical researchers at U.S. universities and other nonprofit institutions.
