Description
Beam-driven plasma wakefield acceleration is a leading candidate for a future electron–positron collider, but it requires transferring a large amount of energy and precise control of the plasma profile. Laser-ionized plasma sources offer significant advantages in meeting these demands. In this work, we present a detailed characterization and simulation of a laser-ionized, all-optical plasma source. We demonstrate—for the first time—high energy transfer with high total efficiency in a beam-loaded PWFA, along with up to 100% witness charge capture in an all-optical plasma soruce, in good agreement with simulations. We also show how this approach can be extended toward positron acceleration. These results establish laser-ionized plasmas as a controllable and high-performance platform for PWFA, and mark an important step toward collider-relevant operation.
