Description
We present recent results on high-power guiding and laser wakefield acceleration (LWFA) in the ELBA beamline at ELI Beamlines, driven by the L3-HAPLS laser system (13 J, 30 fs, 0.2 Hz). By employing self-waveguiding in a 20 cm helium plasma channel, we achieved stable acceleration of electron beams to energies of ~5 GeV. A novel all-reflective optical setup, incorporating an off-axis reflective axicon, enables efficient acceleration at 0.2 Hz and optical guiding at repetition rates up to 3.3 Hz. This compact, single-laser, single-compressor implementation of plasma channels improves electron beam pointing stability and enhances energy gain without requiring modifications to the laser system, paving the way for broader adoption of this approach at user facilities.
