摘要: The self-modulation instability is a key effect that makes possible the usage of nowadays proton beams as drivers for plasma wakefield acceleration. Development in uniform plasmas and with small density up-step numerically studied focus at nonlinear stages beam evolution. step parameters providing strongest established are found, mechanism stable bunch train formation identified.
