Scouts Visit Lab as Part of Nuclear Science Day

About 230 girl scouts, boy scouts and their leaders came to the Lab on April 29 and enjoyed a full day of science activities. The event attracted youth from local communities, and as far away as Stanislaus and Orange counties. Volunteers conducted Advanced Light Source tours, ran hands-on activities, discussed their research, and served as role models. More>

Two ATAP Researchers Receive Recognition

Kelly Swanson (left, with Wim Leemans), a doctoral student in the BELLA Center, took top honors in a speed-storytelling “Grad Slam” event where she spoke about tabletop accelerators. Serena Persichelli, who is working on conceptual studies for ALS-U, won CERN’s Future Circular Collider Diversity Prize. Both are with the Accelerator Technology and Applied Physics Division.

It’s Time for Particle Physics to go Back to the Future

As the Large Hadron Collider nears its energy limits, and the next great collider won’t be ready for decades, can the ensuing generation of young minds sit on the sidelines waiting? In a Scientific American guest blog, Savas Dimopoulos suggests focusing on table-top experiments and mentions the work of the Lab’s Surjeet Rajendran, among others. More>

Laser R&D Focuses on Next-Gen Particle Collider

A set of new laser systems and proposed upgrades at BELLA will propel long-term plans for a more compact and affordable ultrahigh-energy particle collider. This advance could also provide many spinoffs, such as a new tool to hunt for radioactive materials, and a miniaturized and highly tunable free-electron laser system enabling a range of science experiments.

Avoiding the Wave That Wasn’t There

A phenomenon called the numerical Cherenkov instability has long been an obstacle to using particle-in-cell codes for plasma modeling, sometimes causing wildly unphysical false results. Now a multi-institutional team that includes researchers from ATAP’s Accelerator Modeling Program appears to have found a way to avoid it for most practical cases. More>
