The laser-driven wakefield and the density of ionized electrons are analyzed during the pulse propagation through the gas jet. The laser and plasma quantities were chosen in order to have the system operating in the self-modulated regime. Results show how the self-modulation fragments the laser pulse, originating higher-amplitude pulses that can induce bubble formation with wave-breaking and particle injection.1721-1724openAccesselectron densityplasma simulationwakefield acceleratorslaserspulsesTexto completo de evento10.18429/JACoW-IPAC2021-TUPAB1430000-0003-0092-93570000-0001-7762-8961https://orcid.org/0000-0003-0092-9357https://orcid.org/0000-0001-7762-8961
