4. To be completed SPARC Eupraxia
BD studies to reproduce the experimental results on the generation of witness-driver beams in the comb-like configuration obtained at SPARC.
Eupraxia
Driver and witness transport up to the plasma entrance in the comb-like configuration (same simulation).
BD studies to reproduce the 30 pC Eupraxia WP in the SPARC photoinjector with C-band cavity.
Technical Note on the injector useful for the 30 pC Eupraxia WP
