Scientists have developed a new theoretical model for preparing particle accelerator structures made of niobium metal. The model predicts how oxygen in the thin oxide layer on the surface of the niobium metal moves deeper into the metal during heat treatment. Tests indicate that the treatment should improve accelerator structure performance and make accelerators easier to build.
Scientists have reported new clues to solving a cosmic conundrum: How the quark-gluon plasma – nature’s perfect fluid – evolved into the building blocks of matter during the birth of the early universe.
In a new study from the U.S. Department of Energy’s Argonne National Laboratory, researchers have demonstrated a new material that has an excellent balance of parameters needed to generate a good accelerator beam.
Using the nation’s fastest supercomputer, Summit at Oak Ridge National Laboratory, a team of nuclear physicists developed a promising method for measuring quark interactions in hadrons and applied the method to simulations using quarks with close-to-physical masses.
After more than 15 years of work, scientists at three DOE national laboratories have succeeded in creating and testing an advanced, more powerful superconducting magnet made of niobium and tin for use in the next generation of light sources.
A new, compact system has been successfully demonstrated at the Berkeley Lab Laser Accelerator (BELLA) Center to provide simultaneous high-resolution measurements of multiple electron-beam properties.
At the Department of Energy’s SLAC National Accelerator Laboratory, machine learning is opening new avenues to advance the lab’s unique scientific facilities and research.
Their work uses machine learning to transform the way scientists tune particle accelerators for experiments and solve longstanding mysteries in astrophysics and cosmology.
A new paradigm in particle accelerator design paves the way to dramatically smaller accelerators. The novel “dephasingless laser wakefield accelerator” concept uses a new technology called “flying focus.” That combines special optics to shape an ultra-short, high-intensity laser pulse.
The NSF has awarded the San Diego Supercomputer Center (SDSC) at UC San Diego a $5 million grant to develop a high-performance resource for conducting artificial intelligence (AI) research across a wide swath of science and engineering domains.
Nobuo Sato is working to put the know in femto. He’s just been awarded a five-year, multimillion dollar research grant by the Department of Energy to develop a “FemtoAnalyzer” that will help nuclear physicists image the three-dimensional internal structure of protons and neutrons. Now, Sato is among 76 scientists nationwide who have been awarded a grant through the DOE Office of Science’s Early Career Research Program to pursue their research.
An upgrade of the Advanced Light Source, a synchrotron at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab), has passed an important milestone that will help to maintain the ALS’ world-leading capabilities. On Dec. 23 the DOE granted approval for a key funding step that will allow the project to start construction on a new inner electron storage ring known as an accumulator ring.
While particle accelerators may be on the cutting edge of science, the building and preparation of some particle accelerator components has long been more of an art form, dependent on recipes born of trial and error. Now, Ari Deibert Palczewski hopes to change that. A staff scientist at the Department of Energy’s Thomas Jefferson National Accelerator Facility, Palczewski has been awarded a DOE Early Career Research Program grant to put the science back into particle accelerator preparation.
