Employing colliding-pulse injection has been shown to enable the generation of high-quality electron beams from laser–plasma accelerators. Here, by using test particle simulations, Hamiltonian analysis, and multidimensional particle-in-cell we lay theoretical framework for spin-polarized beam in scheme. Furthermore, show that this scheme enables production quasi-monoenergetic excess 80% polarization tens pC charge with commercial 10-TW-class laser systems.
