Description
The E31x program at SLAC FACET-II encompasses five distinct but complementary experiments: E-311 (Plasma Torch Injection), E-313 (Multibunch Dechirper), E-315 (Plasma Afterglow Attosecond Metrology), and E-316 (Icarus).These experiments represent a synergistic set of plasma wakefield acceleration (PWFA) experiments utilizing the unique combination of multi-kA electron bunches at 10 GeV and laser-ionized plasmas. Control over selective ionization of different gas species in PWFA crucially enables advanced ionization injection, acceleration, energy spread compensation, and diagnostics of ultra-high brightness electron beams. A recent upgrade to the probe laser system at FACET-II allowed the first experimental runs across this program. We present initial results from these runs, which will collectively establish a solid foundation for the forthcoming E-310 Trojan Horse-II experiments — the PWFA injection scheme with significant potential for producing high-quality, high-brightness electron beams.
