Study of electron density in capillary discharge plasma for laser plasma accelerator
Original language description
Gas-filled capillary discharge has emerged as a promising source in plasma-based accelerators. Pre-formed plasma channels enhance stability in Laser-Wakefield Accelerators by overcoming diffraction effects and maintaining laser focus over longer distances, thereby increasing energy transfer efficiency. Also, due to their limited gas consumption, they are well-suited for high repetition rate applications. Using Stark broadening, we measured profiles under varying conditions, achieving densities of (2–3) x 1018 cm-3. Moreover, we present three-dimensional (3D) Particle-In-Cell (PIC) simulations incorporating experimentally measured plasma density profiles. The simulation results reveal electron injection and acceleration, with electrons attaining a mean energy of 0.5 GeV using a laser pulse of 2.0 J energy. This type of plasma source is a crucial technology for the 100 Hz plasma accelerator-based Free Electron Laser (FEL) being developed at ELI-ERIC and for the EuPRAXIA project.
