Record setting electron beam: 5 times stronger than its predecessor
Claudio Emma and Brendan O’Shea will look into the experimental equipment in 2022 on the Facet-II. Credit: Jacqueline Ramseyer Orrell/SLAC National Accelerator Laboratory Scientists have created ultra-train electron beams with five times the peak currents than any other similar beam on Earth. This achievement, as described in a paper published in a physical review letter, addresses one of the epic…

Physicists achieve record-breaking electron beam output and current
Schematic diagram of an ultra-high current, extreme beam generation experiment. Credit: arxiv doi: 10.48550/arxiv.2411.10413 A team of physicists from the SLAC National Accelerator Laboratory in Menlo Park, California produced the highest peak power electron beam ever produced. The team publishes the papers in physical review letters. Over the years, scientists have found new uses for powerful laser light, from splitting…

Relativistic electron beam could propel spacecraft to Alpha Centauri, study suggests
Diagram of the electron beam statite used in the study. Credit: arXiv (2024). DOI: 10.48550/arxiv.2407.09414 Getting a spaceship to another star is a tremendous challenge. But that doesn’t stop people from working on it. The most prominent groups currently doing so are Breakthrough Starshot and Tau Zero Foundation, both of which focus on very specific types of propulsion beam power.…

Engineers create chip-based tractor beam for biological particles
Integrated OPA tweezers concept. Credit: Nature Communications (2024). DOI: 10.1038/s41467-024-52273-x Researchers at MIT have developed a small chip-based “tractor beam” similar to the one seen on the Millennium Falcon in the “Star Wars” movies. This could one day help biologists and clinicians study DNA, classify cells, and investigate disease mechanisms. . The study is published in the journal Nature Communications.…
