“…In order to evaluate their effects, we performed beam dynamics simulations in the plasma by employing the code Architect. [23][24][25] Since the scope is to highlight the safe focusing regions, with little impact on emittance, we employed a simplified setting consisting of a 5 mm long plasma with longitudinally constant density. Final beam emittance values are reported in Fig.…”

We report on the experimental characterization of the effect that a passive plasma lens in the\ud overdense regime has on high-brightness bunch quality by means of 6D phase-space analysis. The\ud passive lens is generated by confining hydrogen gas with a capillary tube pre-ionized with a highvoltage\ud discharge. We observed that the optimum condition is retrieved at the end of the overdense\ud regime with almost no effect on bunch brightness. The presence of gas jets, leaking from the hollow\ud capillary end-points, extends the lens effects also outside of the capillary, resulting in longer\ud focusing channels. Experimental results are supported with numerical simulations of the complete\ud accelerator line together with the plasma channel sectio

“…In these conditions, the accelerated field experienced is 1.1 GV=m. Simulations have been performed with the Architect code [49,50], where the electron bunch is treated in 3D PIC and the plasma background in cylindrical fluid. With the beam parameters at the entrance as indicated in Table IV, 40 pC charge can be accelerated to 1 GeV after 40-cm-long plasma at 1.0 × 10 16 cm −3 density contained in a capillary.…”

From plasma-wakefield acceleration as a physics experiment toward a plasma-based accelerator as a user facility, the beam physics issues remaining to be solved are still numerous. Providing beams with high energy, charge, and quality simultaneously, not only within the plasma but also at the user doorstep itself, is the main concern. Despite its tremendous efficiency in particle acceleration, the wakefield displays a complex 3D profile which, associated to the beam-loading field induced by the accelerated beam itself, makes the acceleration of high charge to high energy often incompatible with high beam quality. Beam extraction from the plasma without quality degradation for a transfer either to the next plasma stage or to the user application is another difficulty to consider. This article presents the substantial studies carried out and the different innovative methods employed for tackling all these different issues. Efforts focused on achieving the challenging beam parameters targeted by the EuPRAXIA accelerator facility project. The lessons learned at the end of these in-depth simulations and optimizations are highlighted. The sensitivity to different error sources is also estimated to point out the critical components of such an accelerator. Finally, the needs in terms of laser and plasma parameters are provided.

“…For clarity, the driver and witness parameters are also listed in table 1, while in Fig.1 is shown the accelerating scheme. Simulations have been performed with the time explicit hybrid kinetic-fluid code Architect [17,18] Beams are treated kinetically in a 6D space with conventional particle in cell schemes, while the background plasma electrons are modeled as a cold relativistic fluid. The electromagnetic fields that cause the motion are generated by the sum of the currents of the beams and the background plasma.…”

In the context of plasma wakefield acceleration beam driven, we exploit a high density charge trailing bunch whose selffields act by mitigating the energy spread increase via beam loading compensation, together with bunch self-contain operated by the self-consistent transverse field. The work, that will be experimentally tested in the SPARC LAB test facility, consists of a parametric scan that allows to find optimized parameters in order to preserve the high quality of the trailing bunch over the entire centimeters acceleration length, with a final energy spread increase of 0.1% and an emittance increase of 5 nm. The stability of trailing bunch parameters after acceleration is tested employing a systematic scan of the parameters of the bunches at the injection. The results show that the energy spread increase keeps lower than 1% and the emittance increase is lower than 0.02 mm mrad in all the simulations performed. The energy jitter is of the order of 5%.
