Abstract
Laser plasma-based particle accelerators are attracting significant interest due to the limitations of conventional accelerators in size, cost, and beam parameters. This research demonstrates that interacting petawatt-class laser pulses with a pre-formed micrometer-sized cryogenic hydrogen jet plasma overcomes limitations in producing high-radiation doses at high particle energies. The near-critical plasma density profile generated produces proton energies up to 80 MeV, showcasing a transition between different acceleration schemes, suggesting enhanced acceleration at the relativistic transparency front.
