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…
