  • Plasma accelerators driven by particle beams are a promising technology, but the acceleration distance and energy gain are strongly limited by head erosion in a high-ionization-potential gas. Here the authors observe up to 130% energy boost in a self-focused electron beam, with limited head erosion.

  • Plasma wakefield accelerators produce gradients that are orders of magnitude larger than in conventional particle accelerator, but beams tend to be disrupted by transverse forces. Here the authors create an extended hollow plasma channel, which accelerates positrons without generating transverse forces.

  • A key challenge for compact accelerators is boosting an electron beam’s energy without

    sacrificing its brightness. Here, the authors demonstrate the concept of a plasma wakefield

    ‘dual transformer’, which simultaneously increases both beam energy and brightness of an

    electron bunch injected from the plasma at SLAC.

  • Scientists demonstrate a Compton-based electromagnetic source based on a laser-plasma accelerator and a plasma mirror. The source generates a broadband spectrum of X-rays and is 10,000 times brighter than Compton X-ray sources based on conventional accelerators.

  • The largely unexplored strong-field QED regime in high-field science could be probed using high-energy particle beams and high-intensity lasers. Here the authors propose a concept to probe strong-field QED by harnessing the interaction between an ultrarelativistic electron beam and a solid and whose setup is based on the collision between the high-density beam and the self-fields reflected at the plasma boundary.
