Multi-GeV Electron Combs from a Plasma Wakefield Accelerator
Chaojie Zhang, Douglas Storey, Alexander Knetsch +16
Plasma accelerators now produce GeV-class electron beams with brightness and stability sufficient to drive free-electron lasers. Beyond this, they possess a unique yet largely unex…
First results from the E302 efficiency$\unicode{x2013}$instability experiment at the FACET-II facility
O. G. Finnerud, E. Adli, R. Ariniello +18
The beam-breakup (BBU) instability in plasma accelerators is seeded by a transverse offset between the driver and a trailing bunch. The BBU instability induces oscillations in the…
Drive beam depletion with multi-Joule energy transfer in a plasma wakefield accelerator
R. Ariniello, V. Lee, D. Storey +7
A collider based on beam-driven plasma wakefield acceleration will require the drive beam to transfer 10-100s of Joules to the plasma in each stage, with a drive-to-wake energy tra…
Demonstration of a tandem lens for producing shaped laser-ionized plasmas for plasma wakefield acceleration
R. Ariniello, V. Lee, M. D. Litos
We demonstrate a tandem lens optical setup, comprising two diffractive optics, that focuses a high-power ultrafast laser with a shaped on-axis intensity profile, producing a meter-…
Precision alignment and tolerance of a plasma wakefield accelerator in a laser-ionized plasma source
Valentina Lee, Robert Ariniello, Douglas Storey +9
We present a novel method for aligning a laser ionized plasma source to a pair of ultra-relativistic electron beams that comprise a plasma wakefield accelerator (PWFA). We achieve…
A High-Flux Electron Detector System to Measure Non-linear Compton Scattering at LUXE
Antonios Athanassiadis, Robert Ariniello, Louis Helary +14
Recently, advancements in high-intensity laser technology have enabled the exploration of non-perturbative Quantum Electrodynamics (QED) in strong-field regimes. Notable aspects in…
