Electron beam properties in self-modulated laser wakefield acceleration using TW and sub-TW pulses

Creation and spatial-temporal characterization of gas targets and plasmas for laser-electron acceleration

“…In 2021, our research group and collaborators published a work [58] using PIC simulations to study the generation of MeV electron bunches in the SM-LWFA regime, driven by a few TW and sub-TW laser pulses. This kind of investigation had already been explored by our group since 2017, motivating the work described in this PhD thesis, and resulting in publications in international conference proceedings [111,112] . In this section, some outcomes from the publication of 2021 are discussed in order to elucidate the further experimental activities of our group as well as of this thesis.…”

“…Particle-in-cell (PIC) simulations have been showing us the possibility to generate tens of MeV electron bunches by SM-LWFA, using TW or sub-TW laser pulses and gaseous targets with submillimetric dimensions [58,111,112,113,114] . In addition to computational PIC simulation support, we are currently focusing efforts on several developments required for a LWFA installation, such as a source of high-peak-power laser pulses [115] , proper gaseous and plasma target creation [116,117] , and development and implementation of diagnostic tools to assist and monitor the experiments [118,119] .…”
