A Laser-Plasma Positron Accelerator using Particle-Shower Plasma-Wave interactions.
An all-optical laser-plasma positron accelerator is introduced and modeled using the interaction of laser-driven particle-showers with laser-driven electron plasma-waves. The principle uncovered here shows the trapping and acceleration of positrons that are part of a laser-driven electromagnetic positron-electron shower in a laser-driven plasma wave. The proof of this principle using Particle-In-Cell simulations shows the production of hundreds of MeV beams with pico-Coulomb scale charge using existing lasers. By eliminating the dependence on kilometer-scale radio-frequency accelerators, this centimeter-scale accelerator makes high-energy positron beams widely accessible.

Keeping up-to-date with research can feel impossible, with papers being published faster than you'll ever be able to read them. That's where Researcher comes in: we're simplifying discovery and making important discussions happen. With over 19,000 sources, including peer-reviewed journals, preprints, blogs, universities, podcasts and Live events across 10 research areas, you'll never miss what's important to you. It's like social media, but better. Oh, and we should mention - it's free.
Researcher displays publicly available abstracts and doesn’t host any full article content. If the content is open access, we will direct clicks from the abstracts to the publisher website and display the PDF copy on our platform. Clicks to view the full text will be directed to the publisher website, where only users with subscriptions or access through their institution are able to view the full article.
