| Title | Challenges of moderate energy external injection into Laser-driven Wakefield Accelerators |

| Abstract | Laser Wakefield Acceleration (LWFA) enables GV/m acceleration gradients, promising compact accelerator designs with advantages in cost, environmental impact and portability. Standard LWFA schemes can suffer from poor shot-to-shot stability and beam quality, resulting in broad energy spectrums, beam current variations, high emittance and limited intensity. External injection schemes attempt to overcome such challenges by treating the LWFA stage as purely an accelerating structure and not as a source. Motivated by the pursuit of compactness, external injection of moderate-energy (< 60 MeV) electron beams into plasma will be explored using the Fourier-Bessel Particle-In-Cell (FBPIC) code. The sensitivity of the final beam quality to sub-optimal injection parameters will be explored. Bayesian optimisation is employed to assess whether sub-optimal injection parameters can be compensated for with laser and plasma parameters. This investigation presents working points from which future compact external injection designs can be optimised. |
