Description
A train of charged particle bunches can resonantly drive large amplitude wakefields in plasma, when spaced by integers of one plasma wavelength, and high-transformer-ratio wakefields, when spaced by integers of half plasma wavelength and with properly ramped bunch density. We show with numerical simulations that the SPARC_LAB linear accelerator can provide a train of compressed electron bunches via the velocity bunching technique, and that the coupling between the bunch train and plasma can allow for large-amplitude wakefield excitation (resonant configuration) and for high-transformer-ratio acceleration (anti-resonant configuration). We discuss the experimental plan at SPARC_LAB.
