Researchers positioned lasers to compress billions of electrons together, creating a beam five times more powerful than before.

This is the first measurement of its kind and will enable researchers to evaluate electron dynamics in a new range of super-small particles,  valued  for their ability to trap and manipulate light. 

Scientists studying laser-plasma proton acceleration made an unexpected breakthrough, simultaneously resolving multiple long-standing problems although they had only aimed to address one. 

In 1974, the independent discovery of the J/psi particle at SLAC and Brookhaven National Laboratory rocked the physics world, and entire textbooks had to be rewritten. Earlier this month, SLAC hosted a symposium to celebrate the milestone.

Researchers across the lab are developing AI tools to harness data and particle beams in real time and make molecular movies, speeding up the discovery process in the era of big data.

The high-energy upgrade will keep the U.S. at the forefront of X-ray science and technology, allowing researchers to advance fields such as sustainability, human health and quantum information.

David Cesar, Julia Gonski and W.L. Kimmy Wu will each receive $2.75 million issued over five years for their research in X-ray and ultrafast science, new physics and primordial gravitational waves.

His wide-ranging curiosity, original way of looking at problems and sheer joy in solving them drove many important contributions to particle physics. 

The method could lead to the development of new materials with tailored properties, with potential applications in fields such as climate change, quantum computing and drug design.

Researchers developed new methods that produce intense attosecond pulses and pulse pairs to gain insights into the fastest motions inside atoms and molecules. It could lead to advancements in fields ranging from chemistry to materials science.

An advisory committee recommends the US work to advance three key areas of emerging accelerator technology.

SLAC experimentalists and theorists collaborate to develop critical detector components, data analysis tools, and theoretical models for the HL-LHC upgrade, which will investigate the Higgs boson and pursue physics beyond the Standard Model.
