“…When assuming the use of plasma-based laser mirrors [28,29] to minimize k p L c to values of $10 4 , we find a per-stage emittance increase by a factor ! 11 for electron beams with energies 500 GeV, for a 0 ¼ 2 and r s ¼ p =2, i.e., ' 6:4 Â 10 3 , rendering such beams unusable for applications after multiple stages.…”

We present a study on the emittance evolution of electron bunches, externally injected into laser-driven plasma waves using the three-dimensional particle-in-cell (PIC) code OSIRIS. Results show order-ofmagnitude transverse emittance growth during the injection process, if the electron bunch is not matched to its intrinsic betatron motion inside the wakefield. This behavior is supported by analytic theory reproducing the simulation data to a percent level. The length over which the full emittance growth develops is found to be less than or comparable to the typical dimension of a single plasma module in current multistage designs. In addition, the analytic theory enables the quantitative prediction of emittance degradation in two consecutive accelerators coupled by free-drift sections, excluding this as a scheme for effective emittance-growth suppression, and thus suggests the necessity of beam-matching sections between acceleration stages with fundamental implications on the overall design of staged laser-wakefield accelerators.

“…A feedback controlled, tape-based plasmamirror system (PM) was used to combine the injection beam with the laser driver for the second stage. This PM [12] has a laser energy throughput of 80%, no laser mode or pointing degradations, and has been fully characterized and improved to provide uninterrupted operation at a repetition rate of 1 Hz for hours of run time. Its long term stability was demonstrated in a multi-week experimental campaign on High-Harmonic Generation from a tape [13,14].…”

Abstract. We present initial experiments on staging of two separately driven laser plasma accelerators (LPAs) towards high energy physics and beam deceleration experiments. A study establishing long term stability of electron beams accelerated by an LPA in density downramp configuration [1] is presented, demonstrating the appropriateness of these beams as an injector for staged acceleration. Subsequently, these injector beams are used to longitudinally probe the fully characterized wakefield [2] excited in a discharge-capillary-based second stage accelerator.
