Description
(based on recently published Nat. Commun. 16, 10719 (2025)).
Demonstrating that a plasma-wakefield accelerator operating in the nonlinear regime acts as a transformer to simultaneously boost the energy and brightness of an electron bunch injected from the plasma. Using a 10-GeV drive bunch and a three-stage meter-scale plasma source, electron bunches exceeding 20 GeV with sub-percent energy spread, 2 mm·mrad normalized emittance, and multi-kA peak current were observed. Other important features including high energy-conversion efficiency, an energy transformer ratio exceeding two, and a brightness enhancement over an order of magnitude were also observed
