This report presents the conceptual design of a new European research infrastructure
EuPRAXIA. The concept has been established over the last four years in a unique …

Plasma wakefield accelerators can be driven either by intense laser pulses (LWFA) or by
intense particle beams (PWFA). A third approach that combines the complementary …

Net acceleration of attosecond-scale electron pulses is critical to the development of on-chip
accelerators. We demonstrate a silicon-based laser-driven two-stage accelerator as an …

Plasma photocathode wakefield acceleration combines energy gains of tens of GeV m− 1
with generation of ultralow emittance electron bunches, and opens a path towards 5D …

We present the experimental demonstration of density downramp injection at a gas-dynamic
shock in a beam-driven plasma accelerator. The ultrashort driver electron beam with a peak …

Plasma wakefield acceleration (PWFA) is a novel acceleration technique with promising
prospects for both particle colliders and light sources. However, PWFA research has so far …

We demonstrate a laser-driven, tunable electron lens fabricated in monolithic silicon. The
lens consists of an array of silicon pillars pumped symmetrically by two 300 fs, 1.95 μ m …

Experiments were performed on laser wakefield acceleration in the highly nonlinear regime.
With laser powers P< 250 TW and using an initial spot size larger than the matched spot size …

We present a conceptual design for a hybrid laser-driven plasma wakefield accelerator
(LWFA) to beam-driven plasma wakefield accelerator (PWFA). In this set-up, the output …

The properties of electron beams obtainable from plasma wakefield accelerators are largely
determined by their injection into the plasma wave. Density downramps can facilitate …
