      abstract     = {This work investigates the performance of the electrospray
                      aerosol generator atthe European X-ray Free Electron Laser
                      (EuXFEL). This generator is, togetherwith an aerodynamic
                      lens stack that transports the particles into the
                      X-rayinteraction vacuum chamber, the method of choice to
                      deliver particles for single-particle coherent diffractive
                      imaging (SPI) experiments at the EuXFEL. Forthese
                      experiments to be successful, it is necessary to achieve
                      high transmission ofparticles from solution into the vacuum
                      interaction region. Particle transmissionis highly dependent
                      on efficient neutralization of the charged aerosol
                      generatedby the electrospray mechanism as well as the
                      geometry in the vicinity of theTaylor cone. We report
                      absolute particle transmission values for
                      differentneutralizers and geometries while keeping the
                      conditions suitable for SPIexperiments. Our findings reveal
                      that a vacuum ultraviolet ionizer demonstratesa transmission
                      efficiency approximately seven times greater than the soft
                      X-rayionizer used previously. Combined with an optimized
                      orifice size on the counterelectrode, we achieve > $40\%$
                      particle transmission from solution into the
                      X-rayinteraction region. These findings offer valuable
                      insights for optimizing elec-trospray aerosol generator
                      configurations and data rates for SPI experiments},
