Machine Learning Enhances Light-Beam Performance at the Advanced Light Source

Image - This image shows the profile of an electron beam at Berkeley Lab’s Advanced Light Source synchrotron, represented as pixels measured by a charged coupled device (CCD) sensor. When stabilized by a machine-learning algorithm, the beam has a horizontal size dimension of 49 microns root mean squared and vertical size dimension of 48 microns root mean squared. Some types of experiments require that the corresponding light beam be stable on time scales ranging from seconds to hours to ensure reliable data. (Credit: Lawrence Berkeley National Laboratory)

Sea Quark Surprise Reveals Deeper Complexity in Proton Spin Puzzle

Image - The proton spin puzzle: Scientists want to know how different constituents of the proton contribute to its spin, a fundamental property that plays a role in how these building blocks give rise to nearly all visible matter in the universe. Pieces of the puzzle include the orbital angular momentum of quarks and gluons (top left), gluon spin (top right) and quark and antiquark spin (bottom). The latest data from RHIC reveal that the antiquarks' contribution is more complex than previously thought. (Credit: Brookhaven National Laboratory)

Laser ‘Drill’ Sets a New World Record in Laser-Driven Electron Acceleration

Image - A snapshot of a plasma channel’s electron density profile (blue) formed inside a sapphire tube (gray) with the combination of an electrical discharge and an 8-nanosecond laser pulse (red, orange, yellow). This plasma channel was used to guide femtoseconds-long “driver” laser pulses from the BELLA petawatt laser system, which generated plasma waves and accelerated electrons to 8 billion electron volts in just 20 centimeters.

Preparing for a New Tool to Study the ‘Glue That Binds Us All’

Image - At left is a 1980s conception of the structure of the proton, which is a positively charged particle found in atomic nuclei. At right is our current understanding of the various subatomic particles – including quarks, antiquarks, and gluons – that make up the proton and contribute to a fundamental property known as spin.
