Smilei is a collaborative, open-source, object-oriented (C++) particle-in-cell code. To benefit
from the latest advances in high-performance computing (HPC), Smilei is co-developed by …

Plasma acceleration has emerged as a promising technology for future particle accelerators,
particularly linear colliders. Significant progress has been made in recent decades toward …

We propose a new approach based on an all-optical set-up for generating relativistic
polarized electron beams via vortex Laguerre-Gaussian (LG) laser-driven wakefield …

The acceleration of polarized electrons and protons in strong laser and plasma fields is a
very attractive option to obtain polarized beams in the GeV range. We investigate the …

The stability of plasma-based accelerators against transverse misalignments and
asymmetries of the drive beam is crucial for their applicability. Without stabilizing …

We investigate the precession of electron spins during beam-driven plasma-wakefield
acceleration based on density down-ramp injection by means of full three-dimensional (3D) …

Hosing is a major challenge for the applicability of plasma wakefield accelerators and its
modeling is therefore of fundamental importance to facilitate future stable and compact …

We propose a new method for analytical self-consistent description of the excitation of a
strongly nonlinear wakefield (a bubble) excited by an electron bunch. This method makes it …

We propose a filter method to generate electron beams of high polarization from bubble and
blow-out wakefield accelerators. The mechanism is based on the idea of identifying all …

A classical model of radiation reaction for the betatron oscillation of an electron in a plasma
wakefield accelerator is presented. The maximum energy of the electron due to the …
