Nuclear physics theorists have demonstrated that complex calculations run on supercomputers can accurately predict the distribution of electric charges in mesons, particles made of a quark and an antiquark. The calculations also help validate a method that will be used to make predictions for and analyze data from high-energy experiments at the future Electron-Ion Collider (EIC) at Brookhaven National Laboratory.

Researchers have developed a way to consistently produce 17-4 PH stainless steel using additive manufacturing, or 3D printing. The rapid change in temperatures that occur in these materials after they are heated by the lasers in 3D printers make it difficult to achieve the toughness needed for 17-4 PH steel. This research used bright X-ray beams to observe those fast changes in real time, then altered the chemical composition to compensate for them.

The Scientific Data and Computing Center (SDCC) at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory now stores more than 300 petabytes of data. That's far more data than would be needed to store everything written by humankind since the dawn of history — or, if you prefer your media in video format, all the movies ever created.

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.

Collisions of high energy particles produce “jets” of quarks, anti-quarks, or gluons. The quarks can’t be directly detected, but simulations indicate that the jets modify the quantum vacuum and that the produced quarks retain entanglement.
